HUNGRY MOUTHS TO FEED: W.I. WOODPECKER CHICKS (PT 2)

HUNGRY MOUTHS TO FEED: W.I. WOODPECKER CHICKS (PT 2)

In just a few days, the West Indian WOODPECKER CHICKS have become bigger, noisier and much hungrier. Their heads are now tinged with red. They have started to compete for food: the first chick to push its way to the entrance hole gets the most food. Often there will be a smaller or weaker chick that gets rather left out in the frantic rush for grub (make that ‘grubs’ – see header image). But I suspect quite a lot of food shrapnel gets dropped and spread around inside the nest, so that in the end all the chicks are well sustained.

Rhonda Pearce has been taking photos of this growing family over the last few days, and if you saw my post last week, you will notice that the size of the chicks and the size of the food morsels jammed down their eager gullets has increased considerably…

HUNGRY MOUTHS TO FEED: WEST INDIAN WOODPECKER CHICKS

West Indian Woodpeckers are special. So special that Abaco even has its own subspecies  Melanerpes superciliaris blakei. They are joyful and noisy. They noisily share parenting duties in an admirably modern way. And did I mention they are noisy?

West Indian Woodpeckers & Chicks (Rhonda Pearce)

The parents set up home together, with both partners taking their turns to choose the furnishings and fit out the nest. They share duties on the nest once the eggs have hatched. And they take turns to feed the nestlings as they grow into increasingly hungry and raucous fledglings. 

West Indian Woodpeckers & Chicks (Rhonda Pearce)

This feeding sequence was taken by Rhonda Pearce whose ravenous chick in the header photo is one of the best I have come across. I have never managed to get such a clear shot of desperate chick hunger…  

Here’s how a nest can sound when the chicks are young – a weird sort of insistent purring sound. As the chicks get larger – and more competitive – so the volume level increases.

Get this down your throat, you pesky little rascal…West Indian Woodpeckers & Chicks (Rhonda Pearce)

HOGFISH: BAHAMAS REEF FISH (31)

HOGFISH: BAHAMAS REEF FISH (31)

Hogfish. Fisherman’s delight… getting ‘high on the hog’. This wrasse species Lachnolaimus maximus is a reef denizen, especially where gorgonians are found. It has the distinction of being the only known member of its genus, and because it is IUCN listed as vulnerable, there are strict regulations governing bag, size, and gear limits to protect the species from overfishing.

Hogfish ©Melinda Riger @ G B Scuba

The hogfish gets its name from its long ‘pig-like’ snout, coupled with its rootling behaviour on the sea floor for crustacean prey.

GENDER STUDIES: IT’S COMPLICATED

The hogfish is a sequential hermaphrodite, meaning it changes sex during different life stages. Juvenile hogfish are female, but mature into males at around 3 years old.

Hogfish social groups are organized into harems, where one male will protect a group of females in his territory and mate with them.

CAUTIONARY NOTE Capt. Rick, a loyal follower, has made another of his pertinent comments: “A bit of caution is necessary here! There is some history in the Bahamas of mild to severe Ciguatera poisoning from Hogs. Our M.O. was to only eat Hogs no larger than 5 or 6 lbs. Temporary or permanent blindness, paralysis, and even death is possible with bigger Hogs”. Ciguatera is also a problem with, for example, ‘cuda on Abaco. Those caught on the Marls (west) side are ok to eat; those from the east side have to be treated with circumspection…

SANDWICH TERNS: NO LINK TO BREAD SLICES, SAY SCIENTISTS


Sandwich Tern (Danny Sauvageau)

SANDWICH TERNS: NO LINK TO BREAD SLICES, SAY SCIENTISTS

Have you noticed how newspapers and periodicals increasingly seize every opportunity for a headline ending “…say Scientists”. It lends a spurious authority to any tenuous assertion, like “astronauts unlikely to find cheese on moon, say Scientists” (suggesting at least the faint possibility of some mature cheddar lodged in a crater). Or “Frooty-pops cereal may protect against ingrown toenails, say Scientists”.  To which the proper response is: “research reference please”. But it seems 37.9% of people are actually prepared to believe this tendencious stuff… say Scientists.

But I digress. To the business in hand. The Sandwich Tern (Thalasseus sandvicensis) is a smart-looking medium-sized tern. Its clearest ID signifier among terns is a sharp black beak with a yellow tip. Also, its black legs helpfully distinguish it from other tern species that have orange legs.Sandwich Tern (Sandy Point), Abaco - Bruce Hallett

The origin of the name for this species is an unexpected one. The Thaleasseus (formerly Sterna) simply refers to the sea (Gk). The Sandwich part is more complicated. It’s certainly nothing to do with a tasty filling for a sliced bread snack **. Other bird species such as Branta sandvicensis, an endemic Hawaiian goose, have the name because Hawaii was historically known as the Sandwich Islands. But Sandwich terns are not found there. In fact, the name comes from the town name of Sandwich, Kent UK (sand wic OE – ‘trading post by the sea’). The ornithologist who first described the bird in 1787, John Latham, just happened to live there. (And how fortunate for ornithology that he did not come from Pratts Bottom, also in Kent).

Sandwich Tern, Abaco (Woody Bracey)

Sandwich terns have a wide range around the world. As the range map below show, the most significant breeding area is Great Britain and northern Europe. On Abaco, the birds are uncommon summer residents. Both images above were taken on the main island, the top one at Sandy Point on the jetty (an excellent place for birdwatching, incidentally).Thalasseus_acuflavidus_and_Thalasseus_sandvicensis_map-location-2.svgSarnie Tern range

Like all the Thalasseus terns, the Sandwich tern plunge-dives for fish. I love the sight of diving terns. They hang high in the air as they scope out the water for fish, only to break free from the sky and smash down into the sea, often emerging with a silver prize. Here’s a wonderful photo of one that missed its meal – and one that succeeded.

Sandwich Tern (Danny Sauvageau)Sandwich Tern (Danny Sauvageau) An endearing characteristic of these terns can be seen during their courtship display. The male will catch a fish, then offer it to the female. Her acceptance of the gift signals her readiness to approve the male as a suitable mate. 

Of the  12 tern species recorded for Abaco most are summer residents, some of which breed on Abaco. The royals are the only permanent residents; and the Forster’s are the only winter residents. The other 4 species are transient in migration, or vagrant (arctic tern).

Tern Species on Abaco

As I have mentioned before, a very good source for easy ID to distinguish between different birds of the same family is to head off to BIRDORABLE. The drawings (cartoons!) may not be scientific, but they do highlight the most notable distinctions. Invaluable as a last resort. Or first resort, even! For similar-looking birds, compare the beaks and the legs. The composite below shows how simple it is.

Noisy neighbours? Put this short recording of a sandwich tern colony in the breeding season on a continous loop, and you have the makings of a powerful retaliatory weapon. They’ll be out within a fortnight…

** The food we call a sandwich was named after the 4th Earl of Sandwich. He found eating while playing cards inconvenient, so asked his valet for two slices of bread, requesting “and squash a tern between them, if you’d be so very kind…” The Sandwich Islands were also named after his Lordship by Captain James Cook, as a compliment for financially supporting an expedition there, say Historians…

GETTING THE MEASURE OF TURTLES ON ABACO

GETTING THE MEASURE OF TURTLES ON ABACO

A recent summer course on Abaco was held in partnership between Elizabeth Whitman (Florida International University) and Friends of the Environment/Frank Kenyon Centre. Participants learned about sea turtle biology and ecology, and discussed potential threats to the vulnerable population. After a classroom session, the team headed out to Snake Cay Creek to carry out a field survey. The turtles caught were measured, weighed, tagged (if not already), and given a general health assessment. Each turtle was then released.

The data captured by such courses is invaluable in the continuing assessment of the health of the local turtle population. In addition, such projects provide a valuable opportunity for people to become involved in a fascinating and rewarding local conservation project – with a literally hands-on experience.

SEAHORSES: PREHENSILE TALES FROM THE REEF

It’s a year since I last posted about these amazing little creatures, seahorses. I featured a number of photos by Melinda Riger, a couple of videos, some useful facts about them, and for some reason some useless facts that I came across in researching the post. You can chase it down here: SEAHORSES 1

Adam Rees of SCUBA WORKS is another diver, like Melinda, who combines great underwater experience with wonderful photographic skills. This posts showcases some of Adam’s seahorse photography, and if it doesn’t want to make you explore the reefs, I can’t think what will…

ABACO’S 37 WARBLER SPECIES: AN ILLUSTRATED GUIDE

ABACO’S 37 WARBLER SPECIES: AN ILLUSTRATED GUIDE

Any day now – if not already – winter warblers will be arriving on Abaco. There are 37 warbler species recorded for the main island and the cays. They fall into 3 categories: 5 permanent residents (PR) that breed on Abaco (B), of which two are endemics; 21 winter residents (WR) ranging from ‘everyday’ species to rarities such as the Kirtland’s Warbler; and 11 transients, most of which you will be lucky to encounter. The codes given for each bird show the residence status and also the likelihood of seeing each species in its season, rated from 1 (very likely) to 5 (extreme rarities, maybe only recorded once or twice).

The photos that follow show an example of each warbler, where possible (1) male and (2) taken on Abaco. Where I had no Abaco images – especially with the transients – I have used other mainstream birding resources and Wiki. All due credits at the foot of the post.

This is a slightly revised version of a guide I posted a couple of years ago. Afterwards, I compressed the guide into a pdf which, in theory at least, is downloadable. You could even send it to your phone and add it to your home screen, so that you will never be without a basic guide to the warblers around you. But it’s not as enthralling as Pokemon Go!, I do quite understand…
