8000 

That’s the total number of all the piping plovers (Charadrius melodus) left in the world. Like many other rare and vulnerable species (e.g. the Kirtland’s Warbler), the habitat at both ends of their migration routes is under threat. And, as with the Kirtland’s, vigorous conservation campaigns are underway. Problems such as habitat loss at one end are bad enough – if at both ends, population decline is a certainty and extinction looms. The summer breeding range of PIPLs takes in Canada, central US and the eastern seaboard. In winter they join the mass migration of other birds south to warmer climes. Abaco is lucky enough to receive these little winter visitors; and at Delphi we are fortunate that every year some choose the beach for their winter retreat.

Piping Plover, Abaco (Tony Hepburn)

This is the first of a planned Piping Plover series that I have been working on. The reason for beginning now is because the autumn migrations are starting, and before long a few of this precious species will be on a beach near you on Abaco. Many of them will be ringed as part of the ongoing conservation projects. One of the best ways to monitor success is to follow the migratory lives of these birds; and this can very easily be done by taking photographs of a piping plover that show its rings. The number and colours of the rings on each leg tell the conservationists a great deal about an individual bird. Here is a photo by Don Freiday that shows what to look out for – these 4 items of plover-bling are an integral part of the preservation efforts for this species.

The Audubon Society has produced a wonderful interactive demonstration of the PIPL’s year-round life  that can be found at BEATING THE ODDS. For anyone interested in these fascinating little birds, I highly recommend a click on the link. Some clips are shown below.

A good example of one of the organisations involved in the conservation of PIPLs is CONSERVE WILDLIFE NEW JERSEY, of which Todd Pover and Stephanie Egger are also directly involved on both Abaco and with the CAPE ELEUTHERA INSTITUTE.

With due acknowledgement to Audubon, here are a couple of outstanding photos by Shawn Carey from the site; and below them, details of the range of the Piping Plovers and their 4000-odd mile two-way trip made in the course of each year.

That’s enough to begin with. I will return to PIPLs soon, with more photos, information and links. Meanwhile, here is a great 4-minute video from Plymouth Beach MA. And if you see a Piping Plover on Abaco this autumn and are not part of the ‘bird count community’, please let me know the location; if you can, describe the rings – how many, which legs, what colour; if possible, photograph the bird (and – a big ask – try to include the legs). Whether ringed or not, all data is invaluable and I’ll pass it on.

ABACO’S 5 ‘PERMANENT RESIDENT’ WARBLERS & A NEW WARBLER ID GUIDE

ABACO’S 5 ‘PERMANENT RESIDENT’ WARBLERS & A NEW WARBLER ID GUIDE

There are 37 Warbler species (Parulidae) recorded for Abaco. There is considerable scope for confusion between many of them. For a start, by no means all have the helpful word ‘warbler’ in their name. Secondly a great many of the species are to a greater or lesser extent yellow, with sub-variables for gender, age and season. It’s easy to get in muddle. A good place to start ID is with the warblers that are on Abaco all year round. Only 5 species are permanent residents on Abaco and the Cays: Bahama Warbler, Bahama Yellowthroat, Olive-capped Warbler, Pine warbler and Yellow Warbler. I have used images of these to illustrate this post.

The rest are mostly winter residents, with some being transient visitors passing through on their migration routes. Some are ‘everyday’ birds; some are unusual; and a few are extremely hard to find, the Kirtland’s warbler being the rarest and therefore the most prized sighting of all. I will be returning to the Kirtland’s in more detail in due course.

At the bottom of this post is a complete list of the Abaco warbler species, with Bahamas bird authority Tony White’s excellent codes indicating (a) when they may be seen; and (b) the likelihood of seeing a particular species (from 1 – 5). First however, news of a great resource for aiding warbler ID, produced by The Warbler Guide. Click on the blue link below to open a pdf with illustrative views of warbler species from several angles, spread of 8 pages. These are the warblers of North America, but you’ll find that almost all the Abaco warblers are featured.

PRETTY PALMS: CHEERY WARBLERS ON SUNNY ABACO

PRETTY PALMS: CHEERY WARBLERS ON SUNNY ABACO

Palm Warblers Setophaga palmarum are cheerful little birds. Keen feeders, foraging around on the ground, in the coppice, or where there are pines. They are one of only 3 warbler species that bobs its tail, not just when it’s happy but much of the time. Maybe it is happy much of the time. The other 2 species are the relatively familiar Prairie Warbler; and the vanishingly rare – on Abaco, at least – Kirtland’s Warbler, the avian Holy Grail for birdwatchers on the island. 

The male palm warbler in breeding plumage has a smart chestnut cap and what might be described as a ‘buttery’ BTM, to use a polite text-abbrev. The females are paler and have less yellow on them. The photos below were taken in March this year, mostly by Mrs RH (I can’t now recall who took what so I’ll give a general credit until she claims her ones). You’ll see the wide variety of types of place you might encounter one of these little birds. The last picture isn’t great as a photograph… but it’s a classic bit of acrobatic personal grooming.

ABACO WARBLER CHALLENGE: CAPE MAY WARBLER IDENTIFIED


WARBLER IDENTIFICATION – A LIGHT-HEARTED CHALLENGE

SPECIES ID NOW SOLVED! CUT TO THE CHASE BENEATH THE PHOTOS FOR DETAILS. A LATE ENTRY NOW DISPUTES THE GENDER ID, SO THE SEX CHALLENGE IS REOPENED, SO TO SPEAK

I have previously posted aids to WARBLER ID (1); WARBLER ID (2), a pitfall-fraught area that continues to baffle me despite books, online resources, futile stabs in the dark etc. For each species the male differs from the female, and both differ from juvenile / maturing birds. And this all depends to some extent on the season. Here’s a speckled warbler photographed recently at the Delphi Club, Abaco, for which there are various candidates ranging from the distinctly possible to the frankly completely-unlikely-but-astounding-if-it-turned-out-to-be-true Kirtland’s Warbler. These are seen and positively identified vanishingly rarely on Abaco – maybe one or two a year, and invariably in winter. But what if one decided to stay behind for the summer… And to those who say “Prairie, dimwit”, I reply “…but their speckles don’t cover their entire fronts”.

I’m throwing this open, because although I have a view I’d like to see what others come up with. Craig? Avian101? Avian3? Margaret H? Other birding followers? Are you out there? Leave a comment (see small-print blurb at the bottom of the post) or email me at rollingharbour.delphi@gmail.com The bird was a bit reluctant to be photographed, but I managed to get a side view, a ‘full-frontal’ and a head shot. Any ideas?

UPDATE Thanks to all who came up with suggestions – it’s interesting how opinion on warbler species varies, even with quite clear close-ups to judge from. The first past the post is… Dr Elwood D Bracey (Fl), to whom many thanks. It’s a female CAPE MAY WARBLER Dendroica tigrina. The runner-up is (amazingly) myself – I had it down for a Cape May juvenile, because I thought it looked a bit on the fluffy side… Also, its eye-patches (photo 3) are grey rather than brown, and I took their colouring to be a work in progress. There’ll be some more ID queries from our recent batch of Abaco photos – not just birds, but flowers & shells as well. All contributions will be welcome…

Oh no! What’s happening here? A late challenge has come in from Margaret H (see comments), who contends that the clearly shown patch on the bird’s cheek indicates that it is a male, not a female, Cape May. So the challenge was ended and the award given prematurely… The species is now definite, but the gender ID remains unresolved…

I’ve now heard from Alex Hughes, who writes “[I am] one of Caroline Stahala’s field techs on the parrot project this summer.  She forwarded me the photos of the warbler taken recently on Abaco.  The photos I saw are of a female Cape May Warbler, which is a great find in June!  She is certainly not going to make it to her breeding grounds, unfortunately, but still fascinating to see a boreal forest bird in the Bahamas during summer.

In a follow-up, Alex adds “I’d be very surprised if this was a male bird, due to the plumage lined up with the time of year.  This year’s juvenile birds are not big enough to make the flight south from breeding grounds yet, and wouldn’t anyways if they could.  Therefore, it would have to be adult non-breeding plumage if it were a male, also meaning this bird already molted from alternate plumage from spring, and flew south.  This seems far more unlikely to me than a female who simply didn’t make the flight, probably due to some handicap.  Either way, very cool!”

So I think that wraps it up. A female Cape May, in the right place at the wrong time. How lucky to have got close to one in the off-season. It just goes to show, eager Kirtland hunters, that any of the migratory warbler species might choose to stay behind for the summer…

CORNELL LAB OF ORNITHOLOGY IMAGE & BLURB

“The Cape May Warbler breeds across the boreal forest of Canada and the northern United States, where the fortunes of its populations are largely tied to the availability of spruce budworms, its preferred food. Striking in appearance but poorly understood, the species spends its winters in the West Indies, collecting nectar with its unique curled, semitubular tongue”.

It is presumably using its ‘unique… tongue’ in Photo 2, inconveniently concealed by foliage so we will never know

(RH COMMENT My one obviously liked the Delphi Club – and its feeders – so much that it decided to stay for the summer…)

CAPE MAY WARBLER RANGE MAP (Wiki) (left)

As a warbler-muddler, I am interested to see how extremely selective this species is in its preferred summer and winter latitudes. The banding is very distinct. Are they never tempted by New York? Have they never tried Disneyland?

CORNELL LAB OF ORNITHOLOGY RANGE MAP (below)

The more sophisticated range map below shows the migration areas between the summer breeding and winter non-breeding areas. It looks as though a Cape May warbler on Abaco in June is an unexpected sighting.

BRIGHT & BEAUTIFUL: SUMMER BIRDS AT THE DELPHI CLUB, ABACO


BRIGHT & BEAUTIFUL: SUMMER BIRDS AT THE DELPHI CLUB, ABACO

Peter Mantle reports that some colourful birds have arrived at Delphi to take advantage of the feeders and fresh water provided. Indigo Buntings have been around for a while, as they have been a little further north at BAHAMA PALM SHORES; and Rose-fronted / Red-breasted Grosbeaks (I’m not sure which is correct – the terms seem to be used interchangeably) have been seen all round the Club grounds for a week or more. They haven’t been recorded at Delphi before, so they have now been added to the ever-growing official list of the ‘Birds of Delphi’. How long before an elusive Kirtland’s Warbler puts in an appearance? And will anyone recognise it if it does..?
