‘TYRANTS OF ABACO’: FLYCATCHER ID (1)

LOGGERHEAD vs GRAY KINGBIRD

Gray Kingbird: note dark eye ‘mask’, lighter head, mainly white underside & notched tail

Abaco has 275 (or so) recorded bird species. Omitting the transients, vagrants and (frankly) oddities – hello, feral peafowl of Casuarina – and concentrating on the residents and the summer / winter migrants brings the checklist down considerably. Maybe to around 200. But there is still an awful lot of scope for species confusion. This is frequently found with the warblers (37 species, mostly yellow), shorebirds and (my particular blind spot) gulls & terns with all their gender, age, season and breeding plumage variations. There is one common confusion that surrounds just 4 birds. I’ve decided to tackle the issue because these are the birds I am most frequently asked by people to identify. They send me their photos or a link, or post them on my FB page, and I am always delighted to help. Except… I get confused myself sometimes. So now I plan to demystify the Tyrant Flycatchers (Tyrannidae) of Abaco once and for all. Or for the time being, anyway.

ABACO’S TYRANT FLYCATCHER SPECIES

There are 14 tyrant species recorded for Abaco, as listed in the checklist clip above taken from “THE BIRDS OF ABACO” (a FORK-TAILED FLYCATCHER was seen recently for the first time on Abaco, and will in due course be added to the checklist). You’ll be relieved to learn that we can at once dispense of 10 of the above for present purposes. In practical terms – i.e. everyday life – the only flycatchers you need to be concerned with are the 4 underlined in red above: Cuban Pewee, Gray Kingbird, La Sagra’s Flycatcher and Loggerhead Kingbird. The underlined codes provide useful information for each bird .

PR 3 of the 4 are permanent residents – not the gray kingbird, which is SR a summer resident
B these 4 are the only flycatchers that breed on Abaco
1 all 4 are widespread, commonly and easily found. All other candidates are unusual to very rare

Which is this?

LOGGERHEAD Tyrannus caudifasciatus vs GRAY Tyrannus dominicensis

DIFFERENCES and SIMILARITIES

TOP TIP ANY KINGBIRD SEEN IN WINTER WILL BE A LOGGERHEAD

A kingbird seen between (say) October and March is a Loggerhead. Grays are strictly summer visitors
Both are medium size birds and roughly the same size as adults (around 23 cms)
Loggerheads have dark brownish heads (some say black), grays have lighter, slate-coloured heads
Loggerheads have a ‘squared’ tip to the tail; grays have a notched tip
Loggerheads may have a whitish fringe at the tip of the tail; grays not so
Loggerheads have yellowish tinges to their white undersides & forewings; grays less so or not at all
Grays have a dark or black ‘mask’ through the eyes, often clear but not always easy to see
Loggerheads allegedly have inconspicuous orange head crests; grays are red. I’ve never seen either!
[*RH opinion alert*] Grays have larger, heavier beaks than loggerheads
Grays are territorially aggressive; when they turn up, the loggerheads tend to retreat to the forest

Here is how David Sibley shows the differences

Illustrations: David Allen Sibley

Gray or Loggerhead? Note the light head, discernible mask & notched tail

Loggerhead or Gray? Note the darker head and no mask

GRAY KINGBIRDS: masked & notch-tailed

CLASSIC LOGGERHEAD: squarer tail, yellowish underside, dark head, hint of a crest

COMMON TO ALL FLYCATCHERS An Insect ‘Hook’ at the tip of this Loggerhead’s ‘top’ bill

MEMORABLE FACT TO DEPLOY IN CONVERSATION

The collective names for a group of kingbirds are: a Court, a Coronation, or a Tyranny

I hope this helps with ID, but it’s fair to say that even the birds shown here don’t conform strictly to the rules. A couple of gray kingbirds have distinctly yellowish undersides. And the real problem is this: you see a medium-size bird. It is hawking for insects. It is high summer. It’s a kingbird. It is 150 feet away, and against the sun. It’s just a darkish bird. You can’t see a notched tail or yellowish underside, still less a mask. But at least you can be confident that you can restrict the ID to just 2 birds… Just ask me which, and I’ll do my best…

BAHAMA MOCKINGBIRD: NEW SUBSPECIES FOR ABACO?

April 9, 2015 by Rolling Harbour

BAHAMA MOCKINGBIRD: NEW SUBSPECIES FOR ABACO?

[Camera. Lights. ACTION] Attenborough, D (for it is he), off-screen, in familiar breathy tones…

“Here, deep in the impenetrable pine forests of the Abaco National Park, lives an incredible bird discovery until recently known only to four people in the world. For here, where the unique Abaco Parrots nest in their underground holes and the rare Kirtland’s Warbler continues its brave stand against extinction… here is a completely new bird subspecies that is destined to take the avian world by storm… the Red-faced Bahama Mockingbird Mimus bahamensis volvensharborii…”

I can’t keep that nonsense up for any longer, you’ll be relieved to hear… But here is the story. Woody Bracey was taking us, with his friend Bill, in search of the rare and elusive Kirtland’s Warbler, about which more soon (*Spoiler Alert* Yes, we did. Four). We had stopped the truck in a remote area of the National Park to listen for and indeed watch parrots. I was in the front of the truck, window down, listening hard when suddenly, right by us, I suddenly heard the beautiful song of a Bahama Mockingbird. Here are two recordings I made the previous year – the first is over 1 min long, the second is only 17 secs.

I grabbed my camera and started to fire away at the bird, which was perched on a dead branch just a few feet away near the edge of the track. I had no time to think about depth of field, light balance, or refrangible focus indices, I just went for it. It was Woody who first noticed the remarkable feature of this bird – its red face. It first, I thought it was just on the chin, but later I saw that the red colouring is above the beak as well.

Woody is one of the most experienced birders in the Bahamas, and he had never come across this variant before. Sometimes a bird may have white patches or some other LEUCISTIC colour variation. But red is something very different. Once we had ruled out blood (no evidence of injury) and strawberry jam (no likelihood of a propensity for sticking face in same), an altogether more exciting possibility began to emerge…

The Bahamas Birding Triumvirate will be debating this find, no doubt. Is this sort of red-faced variant found in any other bird species? Is it a one-off? Or is it perhaps one example of a small subspecies confined to Abaco or the wider Bahamas? Or does it just come from eating red berries, as in photo #3? Has anyone come across a BM like this one? Any comment welcome via the comment box or email.

This is my personal favourite pic, taken while the bird was in mid-song. I’d have liked an ‘open mouth’ shot, but frankly when you find an apparently new bird in the middle of nowhere, you can’t have everything….

Finally, you may well ask “So that’s all very well, but what does a ‘normal’ Bahama Mockingbird look like close-to?” Here’s an example for comparison

STOP PRESS (MAY 2015) The jury is back, the verdict unexciting (as I suppose was inevitable). The Bahamas Birding Sages have concluded that the red markings are simply staining from berries, as seen in #3 above. This is the obvious solution, but I am grateful to those (culminicola in the comments below, and a birding forum where this post has been discussed) who suggested the possibility of red pollen. The pine forest in which we saw this bird doesn’t in fact have flowers – or anyway red-pollened flowers – so berries must be the answer. In short, no Mimus bahamensis volvensharborii…

All photos RH, cheers to Woody for leading the trip and for spotting the unusual features of this bird PDQ

“HANDSOME BIRD, BLUE EYES, LIKES FISH, SEEKS MATE…” REDDISH EGRET ON ABACO

April 8, 2015 by Rolling Harbour

“HANDSOME BIRD, BLUE EYES, LIKES FISH, SEEKS MATE…”

REDDISH EGRET ON ABACO

Reddish Egrets come in two colour schemes, reddish and pure white; and both are available on Abaco. ID hint – among the 10 heron and egret species found on Abaco, these are the only ones with a black tip to the beak. In March, these birds are thinking about fish. They do that every day of the year. But they are also thinking about finding a mate. The colouring of the males intensifies, and in particular the greyish-pinkish base of its beak turns a bright ‘hi babe, how are you doing’ pink. The male RE in this post is resplendent in his breeding plumage. We encountered this RE at Crossing Rocks in the brackish pond area on the opposite side of the highway to the bonefishing jetty. This in an excellent place to check out for herons, egrets and other wading birds such as yellowlegs. The island is at its thinnest point here, with the hard dry land over which the highway passes just a few yards across. On either side it’s basically water, mangroves, and other wetland plants. The RE noticed us at the edge of the pond and put on a little display. This is unlikely to have been a ‘come on’… Conceivably, he wanted to show off his distinctive ‘bad hair day’ styling. More plausibly, he was probably put out by having his fishing disturbed. He wasn’t diverted for long, though, and soon got back to business hunting fish. Sometimes he would stand stock still, poised for a rapid strike into the water with that lethal beak. This is the RE’s classic fishing method, the static hunt. However, there are times for being proactive and chasing down the prey. While bonefishing out on the Marls, I have seen this done from a distance, especially by the white RE morphs. They splash about near the edge of the mangroves, moving back and forth, lifting their long legs high in the vegetation as they hunt down their small silver snacks. Our Crossing Rocks RE was suddenly on a mission… We had to tear ourselves away from this performance, grateful to have seen it at such close quarters. However we went back a few days later while on a birding trip to the pond at Gilpin Point. But that’s a post for another time…

RED HIND GROUPER: BAHAMAS REEF FISH (25)

April 6, 2015 by Rolling Harbour

RED HIND GROUPER: BAHAMAS REEF FISH (25)

The Red Hind is one of several grouper species commonly found in Bahamas waters. Commonly for now, anyway. There is less information available about this species compared with other groupers, but sources seem agreed that it is (a) abundant and (b) IUCN listed ‘least concern’ but (c) heavily fished and (d) delicious.

Red Hind, attended by Cleaner Fish

One problem arises from the fact that Red Hinds form spawning aggregations in particular areas, making them vulnerable to fishing exploitation in those locations, and consequent population decline. Already, some of their spawning areas are protected.

Another threat comes from the degradation of coastal habitats coupled with increasing commercial and recreational fishing. Red Hinds are targeted with speargun, hook and line, fish traps and nets. They may also be by-catch of other fishing operations. Fortunately Marine Protected Areas such as the ones in Abaco waters provide localised protection but these are not found throughout the Red Hind’s range. Closed seasons have been imposed in a few areas, another conservation method that has recently been introduced in the Bahamas for the Nassau grouper.

Getting the right balance between traditional fishing for food, and stock conservation is inevitably a tricky calculation. For the Red Hind, the factors that may result in the population decline of a plentiful species are in plain sight and will continue to be monitored by the various scientific research organisations involved…

WEST INDIAN WOODPECKERS ON ABACO: GUEST POST

April 3, 2015 by Rolling Harbour

WEST INDIAN WOODPECKERS ON ABACO: GUEST POST

The WEST INDIAN WOODPECKER Melanerpes superciliaris is a specialist bird of Abaco, where it is common. The only other island in the Bahamas where it is found is San Salvador, where it is uncommon. Formerly found on Grand Bahama, it is now believed to be extirpated from that island, with no recent recorded sightings. In the early days at Delphi, we had to put up 2 nest boxes under the eaves to discourage the woodpeckers from destroying the woodwork – very effective, since they are now used every year by a pair that raises a family in one of the boxes and, even before the chicks have fledged, are busy kitting out the second box for a second family…

Charmaine Albury is a resident of Man-o-War Cay, Abaco. A photographic contributor to THE BIRDS OF ABACO, she is an enthusiastic birder and very handy with a camera. MOW has had a great winter season for birds, especially warbler species, and Charmaine has been recording her sightings and posting about them regularly. She has now started a photographic Facebook page SEES THE DAY which I commend to anyone wanting an overview of the rich birdlife of Abaco. This post shows some of her excellent recent photographs of West Indian Woodpeckers on Abaco. The male has the striking red crown; the female has a smaller, paler cap.

BOTTLENOSE DOLPHINS IN ABACO WATERS (2): MOTHER & CALF

April 1, 2015 by Rolling Harbour

Sometimes things happen that completely take my breath away. Here is one of those moments, from our recent trip with Charlotte and Diane in the BMMRO research boat. As we returned from whale-watching to base in Sandy Point and moved from the deep dark ocean to the bright blue shallows, we encountered a group of bottlenose dolphins. You can see my recent post featuring some of the adults HERE. That was exciting enough, as they played around the boat. Then another participant appeared…

Notice the dark area behind the adult dolphin…

…which soon separated into a small dark splashing creature with its own fin cutting the waves…

…and next seen keeping pace with its parent

The sharp line between the light and the dark sea is where the sandy shallows abruptly give way to the deep waters of the Grand Bahama Canyon, a massive trench up to 2.5 miles deep with almost vertical cliff walls to the depths in some places

There were less active and splashy moments as the pair swam around together

Then it was back to doing what they like best…

Then some more restful moments… Dolphin Mother & Calf, Sandy Point, Abaco, Bahamas

And finally the pair moved away. On the far horizon, the Massive Mickey Mouse Cruise ship moored at ‘Disney’s Castaway Cay’ (formerly the sober-sounding Gorda Cay), where you can be a Pirate of the Caribbean. Or anyway a very happy Tourist. The choice is yours. Would you like fries with that?

And looking out to sea from the cheerful place that is Castaway Cay, I wonder if a small child was wondering “Ok, love Mickey and his Friends – but I’d also really love to see a wild dolphin swimming free…

PEARLY-EYED THRASHER – ANOTHER NEW BIRD FOUND ON ABACO

March 30, 2015 by Rolling Harbour

PEARLY-EYED THRASHER – ANOTHER NEW BIRD FOUND ON ABACO

Exactly a year ago, the ultimate, complete and utter Checklist of the birds of Abaco, compiled by Tony White with Woody Bracey, was published. It covers 4 pages of close print in THE BIRDS OF ABACO, and lists the 282 species recorded since 1950, including so-called ‘exotics’ but excluding so-called ‘pets’ (sadly your minah bird would not qualify). New sightings had been static since a BLACK-BROWED ALBATROSS had made an unheralded appearance out at sea. In the last year, 5 new species have been recorded. The links to them are listed below. That Checklist already needs an update!

The newest bird in town is the Pearly-eyed Thrasher (Margarops fuscatus). This is a bird in the family Mimidae, along with mockingbirds and the gray catbird. Until last November, no thrasher species had ever been recorded for Abaco. Then there was a sighting of a BROWN THRASHER. Just a few months later, its Pearly-eyed cousin has turned up right in the heart of Treasure Cay, seen by first by Erik Gauger and confirmed by Woody Bracey (each a contributor to THE BIRDS OF ABACO).

This thrasher species is found widely throughout the Caribbean, though with several varieties that are genetically distinct. In the Bahamas, they breed on some of the southern islands. They are known to overwinter on Eleuthera and Cat Island, but have not previously been recorded as far north as Abaco. This sighting is important in suggesting that the species may be beginning to extend its range, although it could of course simply be a one-off ‘vagrant’, as they are officially yet disrespectfully known.

Since the first sightings by Erik & Woody a couple of days ago, Woody has been out again with a camera seeking to obtain photographic evidence of the bird. Last night he sent me a snapshot taken in difficult circumstances – the bird was being hassled by a Eurasian Collared Dove (who should have known better, being a non-native species itself…). The pearly eye is quite clear, as is the speckled front and white end to the underside of the tail. If a clearer shot comes in, I’ll add it. So, TC-based birders, a Rolling Harbour Kalik challenge is on!

STOP PRESS Woody has sent a couple more photos of the PET taken right in the centre of Treasure Cay. Or perhaps there is a second one… and if so, different sexes… and if so, a nest, eggs, chicks, fledglings and in due course a new breeding species on Abaco…

STOP PRESS April 2015 Erik Gauger has now written up his account of his discovery of this new species for Abaco. You can read it HERE (scroll down to the second article on the page)

The other photos I have used are ‘open source’ for obvious reasons, and credited below as far as the information is available…

BOTTLENOSE DOLPHINS IN ABACO WATERS (PART 1)

March 27, 2015 by Rolling Harbour

BOTTLENOSE DOLPHINS IN ABACO WATERS (PART 1)

This seems to be a excellent early Spring for dolphin and whale sightings in Abaco waters. I’ve noticed that people have been posting dolphin sightings on FB recently. In our brief window of opportunity each March, I usually reckon to see 2 or 3 dolphins at most – maybe crossing over to Hope Town on the ferry, or more probably on a fishing trip. This year we saw 2 groups of about 6 off Cherokee while fishing, including calves. On another day, 4 adults made a leisurely progress the whole length of Rolling Harbour while we watched from the balcony of the Delphi Club. I don’t think they have ever been so close to the shore there before. The best was to come.

Near the end of our trip Charlotte Dunn and Diane Claridge invited us to go out with them on the BMMRO research boat. This is equipped with a hydrophonic system that can detect the bleeps, whistles and clicks of cetaceans, and record them for comparison with previous data. This enables particular animals to be identified from their vocalisations. The other method is to note particular features of an animal – damage to a fin, markings on the flank and so on. During the day C & D happily conversed in code: “Is that 132 over there?” “No, it’s got a nick in the fluke, it must be 127…”

As we returned in the RHIB from an amazing day spent at close quarters with beaked whales [more on these soon], we moved from deep dark blue ocean to sandy turquoise shallows. There, just off Rocky Point (near BMMRO HQ at Sandy Point) were half a dozen bottlenose dolphins, including a mother and calf. This post contains a small batch of photos of adults – there’ll be another post shortly featuring the calf…

Here’s a taster for the next post – the calf, just visible close alongside its mother, was being given leaping practice. Watch this blog…

UNDENIABLY NATTY: BLUE-GRAY GNATCATCHERS ON ABACO

March 25, 2015 by Rolling Harbour

UNDENIABLY NATTY: BLUE-GRAY GNATCATCHERS ON ABACO

As I sort through 11,867* recent photographs from Abaco and dump the 99% of them that fall into any of the ‘epic fail’, ‘hopeless’, ‘what on earth?’, ‘why on earth’?, ‘sun-flared’, ‘pitch black’, and ‘bird-butt’ categories, a few are making it through the rigorous editorial process. There will be birds, fish, whales, dolphins, expeditions and scenery in due course, but I’m kicking off with a small bird that is a great favourite, the Blue-gray Gnatcatcher Polioptila caerulea. This is because it is probably the easiest bird to pish, click, whistle or otherwise vocalise from the back of the coppice to the front. Then it gets flirty with the camera, performs cutely, and follows you down the track. The perfect subject except for one thing: they are small and branches / twigs are numerous. So, many shots consist of a magnificently focussed stick or leaf, with a blue-gray blur behind it…

THE WARBLER GUIDE: BOOK OR EASY ID IN NEW APP

March 18, 2015 by Rolling Harbour

THE WARBLER GUIDE: BOOK OR EASY ID IN NEW APP

In 2013 Princeton University published a well-received – indeed award-winning – guide to North American warblers. Its relevance to the Northern Bahamas is that all 37 species of warbler recorded for Abaco are found on its pages. Plus, you can use it in North America as a bonus! Details of the book are given below.

As a follow-up project, Princeton has now produced a Warbler Guide App that looks quite impressive at a glance. It’s not cheap, at £9.99 or dollar equivalent, but with bird apps you generally get what you pay for. Included are song/call IDs for a start, which takes the App a long way beyond mere visual recognition. And the illustrations are from several angles, taking account of the fact that you may not get an ideal broadside view of a bird in the field. Below are a few sample images.

THE OCTOPUS: THERE’S NOTHING QUITE LIKE IT…

I’ve posted about the octopus a couple of times before. The first time was to explore the correct plural of the word ‘and related cephalopod mysteries’. You can see that HERE. More recently there was ‘Marine Bagpipes filled with Ink’, which you can see HERE. Both posts were really a way to show some of Melinda Riger’s stunning underwater photography, with an octopoidal theme. Now I have some more images for you, so I present some new photos of Octopi… erm, Octopodes… erm, Octopuses…

THE PECKING ORDER: FEEDER GREED ON ABACO

March 4, 2015 by Rolling Harbour

THE PECKING ORDER: FEEDER GREED ON ABACO

At Delphi there are several feeders, with seeds for the garden birds in general, and sugar water feeders for the specialist hummingbirds. The seed feeders are the cause of a certain amount of species squabbling, with a pecking order based on size. Smaller birds tend to give way to larger, and either flutter down to the ground to pick up dropped seeds or fly off to the bushes until it’s safe to return. The hummer feeders are also visited by birds with adaptive beaks to fit the tiny holes, such as bananaquits; and birds with long and probing tongues like the resident West Indian woodpeckers. The hummers tend to flit away until the intruders have flown off again.

BLACK-FACED GRASSQUITS

There’s no getting away from it, I’m afraid. BFGs are greedy little birds. Many would also call them dull, but personally I rather like the assertive colouring of the male and the subtle olive shades of the female (but that said I’d trade one in for a painted bunting without a second thought…). They are easily bullied out of the way by GABs (see below), although I have noticed that both species happily coexist on the ground under the feeders, where there is more space for them to pick up fallen seeds.

GREATER ANTILLEAN BULLFINCH

These fine birds with their striking livery assume feeder priority. They are just as voracious as the BFGs, and get seriously stuck in. No other birds spoil their feasting. These are alpha seed guzzlers.

HEY YOU! GRASSQUIT! DON’T YOU DARE COME ANY CLOSER… MINE!

HUMMINGBIRD FEEDER RIVALS

BANANAQUIT

This bird had been sticking its thin, curved beak in to the tiny holes and drinking until I got a bead on it (with the camera). Annoyingly it then started to sip the spillage, so I missed the shot I really wanted… Meanwhile two Emeralds had retired to the bushed nearby, waiting for their chance at what was after all their own designated feeder.

This is a beak that can easily negotiate a little feeder hole

WEST INDIAN WOODPECKER

When Delphi’s resident woodpeckers decide to try out the hummer feeder, everyone keeps clear. Very meanly, the male takes precedence over the female, despite the fact that in the course of each year she rears two families, moving to the second nesting box to rearrange the furniture even before the chicks in the first box have flown. Nevertheless, she has to wait her turn… Note how the male manages to get his long tongue right into the small hole in the yellow flower…

Meanwhile, Mrs Woody politely waits her turn…

SAW FISH IN THE ABACO MARLS? NO SURPRISE. SAW A SAWFISH? AWESOME!

February 26, 2015 by Rolling Harbour

SAW FISH IN THE ABACO MARLS? NO SURPRISE. SAW A SAWFISH? AWESOME!

Exactly a year ago, an extraordinary find was made out on the Abaco Marls. Almost disguised against the pale mud under the low water was the first sawfish reported for the Marls. This fish is not merely a rarity in the Northern Bahamas: all species of sawfishes worldwide are IUCN listed as Endangered or Critically Endangered.

Sawfish, Abaco Marls Feb 2014 (Photo: Jacque Cannon)

Here is an account of the discovery reported by FRIENDS OF THE ENVIRONMENT: “On a recent fishing trip in the Marls with local guide Justin Sands, Sam and Jacque Cannon had an exciting encounter. As Justin was poling the flats, with Sam on the bow searching for bonefish, Jacque spotted a Sawfish! Jacque and Justin quickly forgot about Sam and his efforts to catch a bonefish and turned their focus to the Sawfish. This is a very rare sighting and one we are happy there was a camera available to document it…” A couple of weeks later I was lucky enough to sit next to Jacque at dinner at the Delphi Club, so I was able to hear at first hand the story of this amazing find. It also turned out to be the perfect time to sign an early copy of “The Birds of Abaco” for Jacque and Sam…

10 ESSENTIAL SAWFISH FACTS

Sawfishes are also known as Carpenter Sharks; their ‘saw’ is called a ROSTRUM
There are 7 species in oceans and seas worldwide, including the Mediterranean
All populations have declined drastically due to habitat loss, overfishing & pollution
The rostrum is used to feel, to dig, to slash & impale or stun its prey, and for defence
Sawfishes are nocturnal creatures and spend a lot of time face down on the sea floor
Like sharks, their skeleton is made of cartilage and not bone.
Some species can grow up to 7m long
They are generally unaggressive unless provoked but fight strongly when caught
Sawfishes are slow breeders, making population recovery more difficult
Babies are called ‘pups’. Their rostrum is flexible and sheathed until after birth

Sawfish seen from below – Atlantis, Nassau, Bahamas (Fred Hsu)

Other sawfish have been seen recently in the Northern Bahamas, though not in Abaco waters. Last summer the Bahamas National Trust posted 2 great images of a Smalltooth Sawfish, saying “BNT was excited to receive these photographs of a Smalltooth Sawfish photographed in the proposed East Grand Bahama National Park – Bersus Cay Area. The sawfish was 12 to 13 feet long and was seen in water that was 2 -3 feet deep. Thank you to Buzz Cox, Island Manager at Deep water Cay for sending us these photos”.

CONSERVATION ISSUES

POPULATION DECLINE As noted above, Sawfish populations have declined to less than 10% of historical levels. The Smalltooth Sawfish – seen above – was once prolific in the Atlantic, Gulf of Mexico, Mediterranean, Black Sea and Indo-Pacific. Population numbers of this species are now estimated at less than 5% to perhaps as low as 1% of their historic levels.

THREAT TO SURVIVAL The threats to their existence are many: habitat loss, overfishing, accidental bycatch, rostrum souvenir hunters (good prices can be obtained), taking them for fins (as a delicacy) or oil from their liver (medicinal).

LEGAL PROTECTION Capturing a sawfish is illegal in certain countries, including the United States. The sale of smalltooth sawfish rostra is prohibited in the United States under the Endangered Species Act. The import for sale of that of any sawfish species is also prohibited. The international trade of sawfish was banned by the CITES convention in June 2007.

For those that want to find out a bit more detail about these issues, there’s plenty on interesting information in a scientific (but readable) paper from NOAA – click the link below

He was so surprised by the sight that he nearly forgot to turn on his camera to take a short video… The second is a longer 5 min video taken off Andros by Grant Johnson of “wild footage of the critically endangered Smalltooth Sawfish (Pristis pectinata). The west side of Andros, Bahamas is one of the last places on Earth that still provides vast refuge for this incredible animal”.

Finally, you may be wondering how exactly the sawfish uses its rostrum to stun fish, as mentioned earlier. Watch this short video – see how quickly it moves, for such an apparently cumbersome and dozy creature…

“PELICAN BRIEF”: BROWN PELICANS AT SANDY POINT, ABACO

February 24, 2015 by Rolling Harbour

“PELICAN BRIEF”: BROWN PELICANS AT SANDY POINT, ABACO

The Brief today is to write about Brown Pelicans at Sandy Point. And to shoehorn in the traditional titular pun somehow (job done!). For those unfamiliar with Abaco, SP is the end of the road. Literally. The island has one highway 120 miles long, mostly straight, from north to nearly south where it curves abruptly west for a while, past the airfield, and when it reaches the ocean at Rocky Point there’s a 90º turn. For a couple of miles, you travel north again into Sandy Point… then stop when you see the sea ahead of you. Dead end. Time to park and explore…

The birding at SP can be very rewarding. Depending on the time of year, you may see ospreys, tropicbirds, heron and egrets of various sorts, kestrels, anis and plenty of shorebirds. The last are found on the narrow beaches and at low tide on the sandbars close to the shore. On the more distant sandbars in Spring, you may see a colony of Magnificent Frigatebirds (or Man-0-War birds), the males with their amazing ‘look-at-me’ bright red throat-balloons (‘gular pouches’) inflated to enhance their wooing prospects. This is exactly the time you’ll realise you haven’t brought your binoculars with you… We’d gone to a (very) informal lunch party at the legendary Nancy’s, but there was activity on the nearby dock that caught my eye. A pair of pelicans were fishing from it, then drying in the sun, then having a little fly around. I only had a rather underwhelming camera with me, so I did what I could in a short time before returning to the matter in hand. Although I watched the birds diving off the dock a few times, I never actually saw them catch anything. Maybe they had already swallowed some hapless little fish before returning to the dock. I was reminded of a poem by a poet called James Montgomery. Here’s his vivid and perhaps overwrought description of pelican feeding habits: Nimbly they seized and secreted their prey, Alive and wriggling in the elastic net, Which Nature hung beneath their grasping beaks; Till, swoln, with captures, the unwieldy burden Clogg’d their slow flight, as heavily to land, These mighty hunters of the deep return’d. There on the cragged cliffs they perch’d at ease, Gorging their hapless victims one by one; Then full and weary, side by side, they slept, Till evening roused them to the chase again. James Montgomery (4 November 1771 – 30 April 1854): Pelican Island, 1828 (canto IV, l. 141)

Watching the water intently

Check out that ‘gular pouch’… Pelicans, like frigatebirds, have them – cormorants too.

After each sortie a certain amount of shaking down, feather fluffing & general drying-off took place

Although these pelicans look generally rather clumsy and ponderous both in flight and on land, they are surprisingly quick and agile in the dive. Occasionally, however, the take-off was a bit ragged… Usually the male took the tallest post from which to survey the scene, but occasionally the female beat him to a good vantage point. I’d never seen pelicans so close-to before. At Delphi they can be seen flying lazily past over the bay, quite high. I’ve seen one in Hope Town, but some distance away. So it was a huge thrill to be able to watch these two birds from the dock itself. You’ll see that the female was ringed (banded), but the male was not. Very soon we’ll be back on Abaco. I’m hoping the pelicans will be at Sandy Point again. And the ospreys. And the Frigatebirds. And that I’ll have remembered the binoculars. And that the Kaliks at Nancy’s will be ice-cold… All photos, RH

It’s a poor photo, but it illustrates the huge wingspan compared to body length…

CHERUBFISH (PYGMY ANGELFISH): BAHAMAS REEF FISH (23)

February 15, 2015 by Rolling Harbour

CHERUBFISH (PYGMY ANGELFISH): BAHAMAS REEF FISH (23)

Time for a bright little denizen of the not-so-deep. The Cherubfish Centropyge argi or pygmy angelfish is a very small (8cm) and distinctively coloured angelfish species. These fish are native to the Caribbean and Gulf of Mexico, and flicker round the coral reefs happily feeding as they go (see the video below to see how busily they forage). Or maybe they are just having a good time…

The Cherubfish is unsurprisingly a popular aquarium species. Don’t rush straight out and buy some though: a typical warning says “like other angel fish, they are not completely 100% reef-safe. Results vary among individual fish and tank qualities (size, feeding, tankmates, etc.), so caution is recommended when adding this fish to a coral tank“. You can read the whys and the wherefores HERE – sadly I lack the vibrant interest in aquaria to go into it myself…

Looking beyond Melinda’s lovely images of the species, I have found that these creatures will often show more yellow at the nose end. Here’s an example of a more two-tone Cherubfish in case you come across one.

I mentioned that Cherubfish flicker around the reefs instead of proceeding serenely and in an orderly fashion. Have a look at this short video to see what active little fish they are.

HUMBLE HOUSE SPARROWS ON ABACO… & EVERYWHERE ELSE!

February 12, 2015 by Rolling Harbour

HUMBLE HOUSE SPARROWS ON ABACO… & EVERYWHERE ELSE!

The House Sparrow is one of the most successful, adaptive and prolific species in the world. THE most, in fact. It is found on every continent (except Antarctica… but I bet there are in fact a few of them pecking around the Ross Ice Shelf for crumbs). It is indigenous to Europe and Asia, and has been introduced elsewhere. So to any birds or people that say house sparrows are boring and common, I would point out that they are world record-holders…

People tend not to photograph house sparrows. Their domesticity and familiarity have rather tended to breed contempt. Besides, there are more impressive birds to capture. In compiling BIRDS OF ABACO, it was surprisingly hard to get hold of sparrow images. We had to take some ‘in-house’ photos as back-up. Although the house sparrow comes into the broad birding category ‘LBJ’ (‘Little Brown Job’), it’s really a bit unfair. The males in particular deserve a second look (then you can go and find some painted buntings if you wish…).

One of the strangest birding features in the UK in the last 20 years has been the virtual elimination of the house sparrow from London and its inner suburbs. Until recently, there were loveable ‘Cockerny Sparrers’ everywhere. Then suddenly the population began to decline, and the rate of loss accelerated quickly. I haven’t seen one in London for years – not in our garden, not in the green squares, not in the trees, not in noisy squawking crowds in Trafalgar Square and Piccadilly Circus. Suddenly a bird that was so common that its presence was taken completely for granted has now become high on any birder’s ‘get’ list for London, and a joy to see… To read a short article on the possible reasons for the decline CLICK HERE. The trouble is that most theories could be applied to other major cities where there are still thriving populations – New York, for example.

It has to be said that the female house sparrow is undeniably less… er… flamboyant than the male, as is the case with most (all?) avians. But they are still pretty birds, in much the same way that a female black-faced grassquit has subtle coloration if you look closely. I took the photo below at MH Airport while hanging around for a plane. The bird wasn’t perched at a very good angle for a memorable shot, or so I thought until I noticed its little wrinkly feet and sharp claws…

A juvenile. Cute, yes, but I’m sorry, it really is quite dull at this stage…

BAHAMA MOCKINGBIRD NEST, CHICKS & FLEDGING VIDEO

BAHAMA MOCKINGBIRD NEST, CHICKS & FLEDGING VIDEO

I tend not to reblog other people’s posts wholesale. For a start, there can be compatibility issues that are tiresome to sort out. Often, they will include material – interesting in its own right – that is applicable to that blog but not to this one… Or it might be inappropriate to add other useful info or images. Sometimes, though, a post is perfect. This is one such time. I have recently started to follow Dominique’s blog WANDER IN NATURE, having come across her post about the Bahama Mockingbird Mimus gundlachii. The Baha Mocker is on the ‘wants list’ of any birder on Abaco. I have never seen a photo of a nest or chick before, far less seen either in real life. So here they are, not on Abaco but only a mockingbird’s flight away!

BAHAMA MOCKINGBIRD TAKES FLIGHT

JUNE 2014 Sometime in the transition between Spring and Summer, I stumbled across a bird’s nest wedged in the top corner of the rose garden. After a much needed boost, I peered in and discovered the bobbing beaks of three little nestlings, so fragile and still without their feathers.

Bahama Mockingbird Chicks (Wander in Nature)

Over the next few days, I hoped to follow their growth and capture them during feeding time with their two parents that had clearly made their presence known. One of the young birds appeared to take over the nest for a while, and eventually took flight into the big wide world.

FIRST FLIGHT

The whole story is here… there’s a great deal of action at this nest!

Here are two recordings of the beautiful song of this bird that I made 18 months ago a short way down a logging track in the pine forest south of Crossing Rocks (before the Y). Note the repetition of particular phrases before the bird moves on to the next sound in its extensive repertoire.

BAHAMAS REEF FISH (22): BLACK GROUPER

February 4, 2015 by Rolling Harbour

BAHAMAS REEF FISH (22): BLACK GROUPER

The Black Grouper is a large fish of the reefs found in the western Atlantic, particularly in the waters of Florida, Bahamas, Caribbean and the Gulf of Mexico. It is a solitary species that mostly prefers the shallow waters around coral reefs.

Formerly plentiful, these groupers (like other grouper species) have moved from an IUCN listing of ‘Least Concern’ to ‘Near-Threatened’. They have the twin disadvantages of being fished for sport and fished for food. As demand for grouper on the menu rises, so does its vulnerability. The species is described as a ‘slow breeder’, so a depleting population has less chance of sustaining numbers.

An adult black grouper’s diet consists of small fish and squid. Juveniles feed primarily on crustaceans. However, certain tiny reef fish are important to the species as ‘cleaners’. You can read about their significance by clicking CLEANING STATIONS Here are examples of two black groupers receiving attention at the same cleaning station. Both also seem to be giving a ride to REMORAS.

Note that this fish has an embedded hook and is trailing a line – one that ‘got away’

Despite the name, black groupers are not all black. They have many shades from dark to olive-coloured to pale. I believe the two photos below are of a grouper known as Arthur, a favourite with divers and definitely off the menu…

The tiny bright blue fish in the photo above are Blue Chromis, a regular accompaniment on any snorkel or dive on a reef. I like the colourful little Fairy Basslet in the next photo

Now that the NASSAU GROUPER has been awarded a closed season to help maintain numbers, it will be interesting to see if the winter fishing ban is extended to the Black Grouper…

RARE AMERICAN ROBINS ON ABACO: MORE SIGHTINGS

February 2, 2015 by Rolling Harbour

In 2012 I wrote a post about the comparative rarity of the American Robin on Abaco, which had surprised me. They overwinter in Florida, and they might conceivably range further more often than they do. It turned out that one or two may be reported one year, none the next. I listed a number of sightings and some comments by Woody Bracey, but I lacked any photos of these birds taken on Abaco. I had to make do with wiki and bad ones taken in the US by me (including stuffed ones in the Natural History Museum, NYC – an act of desperation!). You can see the post HERE

Nina Henry, a photographic contributor to BIRDS OF ABACO, had some good fortune last March 2014 when she found these 3 birds during her trip to Abaco. Maybe March is a good time for them – perhaps a few call in as they start to make their way north for the summer.

Many past sightings have been on the Cays rather than the main island. Here’s a recent photograph taken by Charmaine Albury on Man-o-Way Cay

Meanwhile I have been able to improve slightly on the tiny distant AMRO I posted before, with one taken more recently – still not on Abaco but in NYC. Closer, but definitely no cigar yet…

‘SEXING THE HUMMER’: A GENDER GUIDE TO ABACO’S HUMMINGBIRDS

‘SEXING THE HUMMER’: A GENDER GUIDE TO ABACO’S HUMMINGBIRDS

The subject matter of this post is not as indelicate as the title might imply; nor is it a ‘hands-on’ practical guide for intimate examinations of tiny birds. In particular it does not publicise some recently discovered louche activity involving unfeasibly large motor vehicles. It’s all about plumage. In my thin disguise as a person with apparent knowledge about the wildlife of a country that is not my own, I get frequent requests for bird ID. Some, I know at once. Some I have to think about, my memory not being quite as…

Where was I? Yes, bird ID. I use BRUCE HALLETT’S book of course, and online the CORNELL LAB and AUDUBON sites. OISEUX-BIRDS is also a good resource and has a large archive of images. And of course dear old Google – they may watch your every keystroke and know more about you than you do yourself, but put a bird’s name into Google Images and you’ll probably see your bird in every static pose or flight you need for ID. They’ll log that too for future use. I have had some queries about Bahama Woodstar gender ID, and more recently, Cuban Emeralds. So here are the adult males and females of each species in all their undoubted glory…

WOODSTAR ID MADE EASY

Males have a glorious purple, showy ‘gorget’. Females are less flamboyant, and have grey throats and fronts. Tara’s wonderful photo above vividly demonstrates their more delicate beauty. It’s one of my personal favourites from “BIRDS OF ABACO“, along with Tom Sheley’s above, the bird that graces the jacket.

CUBAN EMERALD (Chlorostilbon ricordii)

Cuban Emerald (male), Abaco (Erik Gauger)

Cuban Emerald (female), Delphi Club, Abaco (Keith Salvesen)

Cuban Emerald (female) Gilpin Point, Abaco (Keith Salvesen)

EMERALD ID MADE EASY

Male emeralds are basically… er… emerald green all over , apart from the wings. Females have grey throats and fronts, and lack the chestnut frontal band of the female woodstar. I’d say that their iridescent green is a different metallic shade from the male, but that may be just me. I don’t have the palette vocab to describe it, but advice welcome! Perhaps one can simply say it is more subtle.

SO IT’S JUST THE TWO HUMMERS ON ABACO, IS IT?

The answer is ‘No’. But don’t make a special trip to see the third species – they are casual / irregular vagrants only, and a definite sighting will be a rarity. But just in case, here are stock photos of a male and a female, and (taken on Abaco by Bruce Hallett) an immature male of the species…
