BLACK-FACED GRASSQUITS ON ABACO, BAHAMAS

A while back, Black-faced Grassquits Tiaris bicolor were honoured by the American Ornithological Union with a classification change from emberizid to tanager. For the reasons that follow, the species regarded this both as scientific promotion and as merited status elevation. I invited an authoritative Spokesquit to explain why.

*******************

Hi, human friends, I’m a black-faced grassquit and I have a couple of observations to make on behalf of BFGs, if I may. First, we seem to be universally described by you as ‘common’, whereas we are actually quite refined in our behaviour. Secondly, the words most used to portray us are ‘dull’ and ‘drab’. And ‘stubby’. Well, excuse me… I – we – ask you to give us a second look. Maybe check out these images for a start.

Unsurprisingly we were very excited when the perceptive classifications committee of the American Ornithological Union gave us an upgrade. That’s the way we saw it anyway. For many years we were classified under the heading emberizidae.

We kept company with some buddies like the handsome Greater Antillean Bullfinches, but also with a lot of New World sparrows, with whom we (frankly) never felt entirely comfortable. Annoyingly chirpy, for a start.

And so we officially became a type of tanager. They even reckon (rather late in the day, in my view) that we are closely related to Darwin’s finches. So, we are “common”, huh? Now we get to be with other birds that are dome-nesters like us. And how about this – we’ll be in the same list as some really cool birds…

How’s this for a colourful gang to be joining: scarlet tanager, summer tanager, rose-breasted grosbeak, indigo bunting, painted bunting – these are our new cousins. BFGs “dull” and “drab”? I don’t think so.

6 UNDULL FACTS ABOUT BFGS

Make grassy dome-nests (like Bananaquits) and line them with soft grasses
Both sexes build the nest together
Both share egg-sitting duties and later chick-feeding & maintenance
Though quite gregarious by day, for some reason they tend to roost alone
They have a short ‘display’ flight with vibrating wings and a strange buzzing call
Otherwise, their flight is ‘weak, bouncy & fluttering’ (Whatbird assessment)

PALM WARBLERS: ‘HEADS-UP FOR BUTTERBUTTS’

PALM WARBLERS: ‘HEADS-UP FOR BUTTERBUTTS’

I realise that the title of this post has its unattractive aspects. This is a family blog, and we try to keep references to ‘butts’ and so forth to a minimum. But like it or not, the Palm Warbler is one of two species** that have acquired the nickname ‘butterbutt’. They weren’t even consulted; birders just went ahead with it without checking how they’d feel about it.

On the other hand, it’s easy to see how this minor linguistic outrage came about. It’s there for all to see, right under the bird’s… erm… stern. That flash of vivid yellow, together with the pale speckled front, a rusty brown cap and striking eye-stripe, is diagnostic for this Abaco winter resident species.

The ‘heads-up’ is because right now they are among you. In the gardens, on the grass, on the tracks, in the coppice, in the casuarinas. And they have an endearing habit of bobbing their… tails, let’s say, as they forage. Palm Warblers are inclined to be fairly inquisitive and tame, so if you are careful, they may stay around to let you watch them.

The PW above must, I think, have been photographed at the very end of the winter season, just before it headed north from Abaco. The strong colours suggest this guy is getting into the breeding mood. Compare him with the picture below, taken by the same photographer during the same period, of a slightly less garish stage of breeding plumage. But it’s on its way…

As often as not, a palm warbler will be fairly easy to spot. Not always, though. You may have to work a bit to locate one half-hidden in foliage. Its posterior may not even be visible.

Luckily, PWs are common enough in winter to give you a chance to shoot them in the open, as it were. Perched on a branch works just fine to capture the essential characteristics.

Keep an eye out for these pretty little warblers. They are enjoyable to watch, and relatively easy to get a photo of at close quarters. Just make sure you get the butterbutt into the picture.

** The other butterbutt bird is the descriptively-named YELLOW-RUMPED WARBLER, though its buttery bits are on the topside so there’s no risk of confusion (I photographed this one from a pool-side lounger, a distance shot at the top of a tree with a small camera – but it captures the essentials!)

ABACO PARROTS FOR THE NEW YEAR!

January 4, 2018 by Rolling Harbour

ABACO PARROTS FOR THE NEW YEAR!

Red, green, blue, and a touch of snowy white. The colours of Christmas, sort of. We are past all that for another year, but for those on Abaco the unique, ground-nesting Abaco parrots Amazona leucocephala flash those same colours throughout the year.

These birds have cousins on Inagua that nest conventionally; and there are now a handful of NASSAU PARROTS on New Providence, of uncertain origin (click link for more on these).

The parrots are only found in South Abaco, between Marsh Harbour and the National Park where they live and breed in limestone holes in the forest floor.

You are most likely to hear these birds before you see them, as they make their way daily north in the morning and back again in the evening.

Despite the racket they make, finding the parrots in the National Park is a bit ‘needle-in-haystack’. Instead, try the Gilpin Point point area, and coppice areas to the north. They pass back and forth over Delphi, pausing to squabble noisily, almost daily. I have made several recordings of them – here’s one example.

Far and away the best location is Bahama Palm Shores, where the mix of dense coppice with their favourite gumbo limbo trees and the open gardens is much to their liking. And frankly, it’s a great place for birding anyway, even if you blank for the parrots.

Just think: a dozen years ago, these fine birds were sliding towards extinction, with an unsustainable population of fewer than 900. Conservation efforts and in particular attention to habitat protection and predator control have resulted in population increases year-on-year, and the total now stands at around 5000 adults.

I’ve posted quite a lot about these parrots over the years, so if you are already familiar with them, I hoped you felt free to skip the text, and simply to admire these wonderful creatures.

LA SAGRA’S FLYCATCHER: SMALL TYRANTS ON ABACO

LA SAGRA’S FLYCATCHER: SMALL TYRANTS ON ABACO

The LA SAGRA’S FLYCATCHER (Myiarchus sagrae) is a common resident breeding species of flycatcher on Abaco, and these very pretty small birds can be seen in many habitats – pine forest, scrubland, coppice and gardens, for example. They are insectivores, as the name suggests, but they also eat seeds and berries.

As a ‘tyrant flycatcher’, this little bird is a member of the large passerine order that includes kingbirds, pewees and phoebes, with which they are sometimes confused. I last wrote about LSFs in the infancy of this blog, illustrated with my own rather… ahem… ‘simple’** photos. Time to revisit them and to do them justice with some new, improved images.‘

‘Simple’ photo from a less complex era, taken with a 2mp ‘Cheepo’™ camera La Sagra's Flycatcher, Abaco - Keith Salvesen

Magnificent photo by Gelinde Taurer that you can actually enlarge (click pic – see?)

Unlike many bird species, adult LSFs are very similar in appearance in both sexes. Whatever the gender, they are sometimes confused with their cousins the Cuban Pewees, but those have a very distinctive eye-crescent.

Cuban Pewee – note eye-crescent, absent in the LSF

Both species have a tiny hook at the end of the (upper) beak – to help trap insects, I assume

Another thing to notice about LSFs is the amount of rufous brown in their plumage, particularly on the wings and tail – and even at the base of the beak. This coloration is absent from their larger cousin kingbirds, the loggerhead and the gray.

WHAT SHOULD I LISTEN OUT FOR?

“A high pitched single or double noted sound described as ‘wink’... ” Or it might be ‘bip‘. Or ‘weep‘. Or (on one recording I listened to, complete with sonograph) it sounded like ‘chi-chitty chew‘. But it may have been a misID.

ANY IDEA WHAT LA SAGRA CHICKS LOOK LIKE?

Well, as it happens, yes. By good fortune Abaco photographer and piping plover monitor Rhonda Pearce happens to have had a nest at hand this very season. So, happy to oblige…

WHO OR WHAT IS A ‘LA SAGRA’ WHEN IT’S AT HOME?

Mr La Sagra was a multi-talented Spanish botanist. Ramón Dionisio José de la Sagra y Peris (1798–1871) was also a writer, economist, sociologist, politician, anarchist, and founder of the world’s first anarchist journal El Porvenir (‘The Future’). At one time he lived in Cuba and became director of Havana’s Botanical Garden. His name lives on more significantly in ornithological than in anarchist circles (actually, ‘anarchist circles’ must be a contradiction in terms… that should be ‘anarchist disorganised squiggles’)

I note in passing that La Sagra is a provincial area in Spain, an Italian festive celebration, a chocolatier, and a small comet… All these meanings may have to be negotiated online before you get to the flycatcher…

Ramón Dionisio José de la Sagra y Peris

Continuing this blog’s philatelic natural history theme, here are stamps from the Cayman Islands and Cuba featuring the La Sagra’s Flycatcher. The Cuban stamp commemorates the death of Juan Gundlach, the man who chose La Sagra’s name to bestow on this bird. And Gundlach’s name lives on in the Bahama Mockingbird Mimus gundlachii…

** ‘Simple’, as in ‘not completely disastrous for an amateur effort but frankly not the sort of standard we have come expect around here’.

BAHAMA MOCKINGBIRDS ON ABACO: GOOD IMPRESSIONS

April 26, 2017 by Rolling Harbour

BAHAMA MOCKINGBIRDS ON ABACO: GOOD IMPRESSIONS

The Bahama Mockingbird Mimus gundlachii is similar to its slightly smaller cousin, the widespread Northern Mockingbird Mimus polyglottis. The range of Bahama Mockingbirds is not restricted to the Bahamas themselves, and includes areas of Cuba, Jamaica and TCI, so despite the name they are not an endemic species to the Bahamas. They are also occasional vagrants to the United States, especially – for reasons of proximity – southeastern Florida.

The Bahama Mockingbird is browner than the greyish Northern Mockingbird, and has distinctive streaking and spotting to its breast and undercarriage. This may extend to what you might describe as the bird’s ‘trouser legs’, though I’m sure there’s a more technically correct term.

Both mockingbird species are found on Abaco. The NMs are ubiquitous in towns, settlements, gardens, coppice and pine forest, whereas BMs are shyer and tend to be found in the pine forest and well away from humans and their operations. When we were putting together The Birds of Abaco, I went on a birding trip with Abaco birding legend Woody Bracey and Ohio bird photographer Tom Sheley. We took a truck into the pine forest down a logging track south of Delphi, and they were quick to locate a bird, not least because one was sitting prettily on a branch singing lustily and unmistakably. It was well within range of Tom’s massive lens; more of a struggle for my modest camera (below). Caught the cobwebs, though…

I was astounded by the beauty and variety of the song. It consisted of very varied notes and phrases, each repeated 3 or 4 times before moving on to the next sounds in the repertoire. Here is a short 18 second example I recorded, using my unpatented iPhone method, for which see HERE.

For those with interest in birdsong, here is a longer 1:13 minute song from the same bird, with largely different sounds from the first recording made minutes earlier. There’s even a decent stab at imitation of a 1960s Trimphone™. Had we not had to move on to Sandy Point for an appointment with some cattle egrets and American kestrels, I could have stayed listening for far longer.

THE ‘SUBSPECIES’ THAT WASN’T…

More recently, on a trip in backcountry to find Kirtland’s warblers – we saw 4 – the slow-moving truck jolted to halt in the middle of nowhere. This was because a Bahama Mockingbird was right by the track. I fired off some quick shots out of the window into a rather difficult light, to find that we appeared to have found a new subspecies, the scarlet-faced mockingbird.

The reason was clear, however. The bird had been pigging out on some red berries, and had managed to collect plenty of the juice round the base of its beak.

SO WHAT DOES A NORTHERN MOCKINGBIRD LOOK LIKE, THEN?

I photographed the Northern Mockingbird below in a garden at Casuarina. The species is far tamer than its cousin, and seen side-by-side they are clearly very different. The range maps show the stark contrast between the very limited range of the Bahama Mockingbird and the vast distribution of the Northern Mockingbird.

NORTHERN PINTAILS ON ABACO: LOOKING SHARP

NORTHERN PINTAILS ON ABACO: LOOKING SHARP

The Northern Pintail Anas acuta is a relatively rare winter resident dabbling duck on Abaco. The species has a huge range, being found throughout much of the northern hemisphere.

DABBLING DUCKS – PINTAILS UP

The ‘acuta’ in the Latin name refers to the characteristic sharp ‘pin tail’. As so often, the drake is a somewhat flashy specimen while the female is unassuming or, as some sources harshly put it, dull and drab. And while the drake makes a melodious whistle, the female simply quacks or croaks.

FLASHY MALE

DULL & DRAB FEMALE? DEBATABLE!

Northern Pintails form flocks and are happy to mix with other species. Their long necks give the edge over similarly-sized dabbling ducks such as the mallard, enabling them to reach deeper down in the water to feed.

THREATS TO THE SPECIES

Predation of nests and chicks by animals and birds such as birds of prey and (some) gulls
Parasites including worms and lice, to which they seem to be susceptible; and avian diseases including bird ‘flu
Hunting: they are a good target species being swift and agile in the air (for sport) yet quite large (for success rate). Also, delicious (for dinner).
Lead poisoning from shot or angling tackle, research has shown. A major problem with all bottom-feeders, though improved where laws prohibiting lead shot have been introduced
Loss of wetland areas to agriculture or due to habitat or climate changes

On Abaco, Northern Pintails arrive in the autumn and leave as spring approaches. They are most likely to be found on ponds such as the one at Treasure Cay Golf Course, where I photographed the male; and at Gilpin Point where I spotted the lone female (at a distance). Below are both genders together for comparison (NB not taken on Abaco).

BREEDING TIME

Mating is aquatic, by the usual anatine method in which the female lowers herself in the water to indicate her agreement to the proposal whereupon the male tries to drown her. Apparently after mating, the male raises his head and whistles – whether as a signal that it’s all over or exaltation or relief has not been researched. Yet.

SHARP-EYED & SHARP-BILLED: GREEN HERON ON ABACO

August 28, 2014 by Rolling Harbour

SHARP-EYED & SHARP-BILLED: GREEN HERON ON ABACO

Abaco has six ‘true’ heron species (putting aside the various egrets): Great Blue Heron, Little Blue Heron, Tricolored Heron, Green Heron, Black-crowned Night-Heron and Yellow-crowned Night-Heron. The Green Heron Butorides virescens is a permanent resident and is easily distinguishable from the other heron species. The header picture by Tom Sheley is one of many wonderful photographs he took for THE BIRDS OF ABACO, and is one of the most striking. This is a bird actively hunting, keeping very low with eyes fixed on the water, waiting for the chance to use that long sharp bill to snaffle its prey – small fish, frogs and aquatic insects.

RANGE MAP

Green Heron Range Map

There are thought to be 5 sub-species of green heron within the range, but this is a matter for anguished debate (not by me). However, the resident variety in the Bahamas has been designated Butorides virescens bahamensis since 1888 (Brewster), so I’m going along with that.

Green Herons are most likely to be seen in or near water – the margins of brackish ponds or amongst the mangroves, for example. Their foraging is mostly done in water, usually at dawn or dusk.

You may encounter one on the shoreline or beach…

…but they don’t always choose the most scenic locations

FASCINATING FACTOID

Green Heron are known to drop food, insects, or small objects such as stones on the water’s surface as bait to attract fish or other tasty creatures. They are thus classified as one of the animal kingdom’s 44 (?) TOOL-USING SPECIES, considered a sign of superior intelligence.

Green Herons may also be found perching in trees

Occasionally they may be seen out at sea – this one from an offshore BMMRO research vessel

The Golf Course at Treasure Cay is an excellent place to go bird-watching. There is always plenty of bird life on the 3 ponds there, the one on hole #11 being the biggest and most abundant. If you are going to bird there, call in first at the Clubhouse and ask for permission: they are very kind about it, but they do need to know who is out on the course. And since the pond is alongside the fairway, keep your wits about you – you are a potential target for the sliced drive… (ok, ok left-handers – hooked, then).

The 2 images above are from Charlie Skinner, and show a green heron adult and chick putting the Golf Course drainage pipe to good use. Captions invited for the top one. Birds often seen at this particular location include green heron, white-cheeked pintail (lots), common gallinule (moorhen), coot, Canada goose, least grebe, neotropic cormorant, and blue-winged teal. You may also see little blue heron and smooth-billed anis. Once I found a least bittern in the background of a teal photo – I didn’t notice it at the time, but when I checked the photos there it was in the reeds behind the ducks. Another good place to bird if you are in the TC area is White Sound.

POSTSCRIPT I’ve just commented HERE on the supposedly phonetic call-sounds attributed to birds to render them recognisable by man – the “What’s-for-dinner-Martha, what’s-for-dinner” and the “Give-me-a-drink-please…NOW” and so on. So when I was borrowing the range map from Wiki I was amused to see this: “The green heron’s call is a loud and sudden kyow; it also makes a series of more subdued kuk calls. During courtship, the male gives a raah-rahh call with wide-open bill, makes noisy wingbeats and whoom-whoom-whoom calls in flight, and sometimes calls roo-roo to the female before landing again. While sitting, an aaroo-aaroo courtship call is also given”. So there you go.
