VIREOS ON ABACO (2): THE PHILADELPHIA VIREO

Vireos haven’t had as much attention as they deserve hereabouts. I have posted about the BLACK-WHISKERED VIREO, but the 7 other vireo species found on Abaco haven’t had much of a look in. It’s a wrong that I shall right at once by featuring the rather shy Philadelphia Vireo Vireo philadelphicus. Here is the full list of the vireos recorded for Abaco, from which you will see that only the Thick-billed Vireo is a common permanent resident. The Black-whiskered vireo is a common summer breeding resident; there are 2 uncommon winter residents; and the other 4 are transients that chose Abaco as a resting place on their migrations.

This little bird tends  to be described with such unkind adjectives as ‘drab’, ‘dull’ and ‘plain’, but  like many under-appreciated species it has its own charm. The header image and the one above give excellent close-up views. The signifiers include the dark eyes, white eyebrows, the dark line through the eyes, the yellow underparts, and in the negative sense the complete absence of eye rings, wing bars or tail markings. And the thick bill is one quick way to distinguish it from similar-looking warbler species, with their generally smaller, pointy beaks. SONY DSC

The Philadelphia Vireo has a wide range, from its summer breeding grounds as far north as Canada down to its winter quarters in Mexico and South America. They have even, very rarely, been seen in Europe. The connection with Philadelphia is somewhat tenuous and arises because the bird was first identified in 1842 from a specimen collected near Philadelphia. However their visits there are brief, since at best it is only a stopover on their migration route…vire_phil_AllAm_map

Here is the song comparison between (in order) the Philly, the familiar TBV whose song accompanies everyday life on Abaco, and the Black-whiskered vireo. My TBV recording is rather quieter than the other 2.

VIREOS ON ABACO (1): GOING CHEEP – THE BLACK-WHISKERED VIREO

GOING CHEEP ON ABACO: THE BLACK-WHISKERED VIREO

There are 8 vireo species recorded for Abaco. The most common is the ubiquitous Thick-billed Vireo Vireo crassirostris – the only permanent resident vireo – whose cheery chirp is part of the background of bird song heard daily all over the island.  The only other species you are likely to encounter without going out of your way is the summer resident BLACK-WHISKERED VIREO Vireo altiloquus, which breeds on Abaco. The other 6 are the White-eyed, Yellow-throated, Blue-headed, Warbling, Philadelphia, and Red-eyed Vireo. Of these, the first 2 are quite rare winter residents; and the other 4 are considered to be transients. Black-whiskered Vireo, Abaco

The BWV’s song is similar to the Thick-billed Vireo, but (luckily) identifiably different. I’m not a great one for phonetic attempts at turning a bird call into a human sentence of the ‘Quick!-come-to-pick-up-a-brick’ and the ‘Skin-me-a-nice-bit-of-bonefish’ type. The Black-whiskered Vireo’s song has been described as sounding like ‘Whip, Tom Kelly’. But not to me. See what you make of it…

As with other vireo species, the BWV has a stout bill, a feature that helps to distinguish vireos from the many thin-billed warbler species on Abaco. The main signifiers are found on this bird’s head: the dark stripe right through the eye; the long white eyebrows; and the noticeable black lines – the ‘whiskers’ – on the sides of the neck. Other identification pointers are the pale underside with a yellow tinge to the flanks and undertail; and the red eyes (the red-eyed vireo, a very similar bird, lacks the whiskers).Black-whiskered Vireo, Abaco (Charmaine Albury)

Black-whiskered vireos feed mostly on insects in trees, bushes and undergrowth. They can sometimes be seen hovering while they forage. They also vary their diet with small quantities of berries. Here are two great shots of a mother BWV feeding a very large chick with a berry, followed by some vile insect.Black-whiskered Vireo, Abaco (Charlie Skinner)Black-whiskered Vireo, Abaco (Charlie Skinner)

ABACO BIRD ID CHALLENGE (FOR NON-EXPERTS): THE SOLUTION


ABACO BIRD ID CHALLENGE (FOR NON-EXPERTS ONLY): THE SOLUTION

This small bird (Oh. I’ve given away the size already) was photographed in June. I was looking through a batch of downloaded photos recently. When I saw it again, I knew at once which bird species it belonged to – but not the specific make. I did some research and came up with the answer. I’d nailed the ID – or thought I had. The photo was a long shot which I had to enlarge to see the markings more clearly, hence a lower overall quality. I sent the jpeg to an officially  avian-knowledgeable person for confirmation (hi, Alex!). The reply was swift. No, not the bird ‘swift’, I mean it was quick. It turns out that I was, as so often, completely wrong. Barking up the wrong tree. Chirping in the wrong nest. Perched on the wrong branch…

I’d say there are two definitely plausible candidates, and you may even think of others. So what bird is it? You can click on it to enlarge it. Please join in and give your answer using ‘leave a comment’ (tiny letters at the end of this post) or email rollingharbour.delphi@gmail.com  Or, if you are seeing this on Facebook, please reply on that.

UPDATE Thanks for emails. Opinion is divided, but one of the 2 candidates is definitely ahead… I’ll leave this over the weekend

SOLUTION Of the few replies, most were right. One or 2 were (wrongly) with me – I reckoned it was a SWAINSON’S WARBLER. No one suggested turkey vulture. The correct ID, and the reasons for it, were provided by Alex Hughes, to whom thanks: “The first bird is a BLACK-WHISKERED VIREO.  The black supercilium going through the eye and the heavy bill are good marks, which can resemble a Swainson’s Warbler, but a clinching mark here is the yellow wash underneath the tail at the rear of the bird”.

While I am dealing with mystery birds, I posted photos of a very sweet little JUVENILE  BANANAQUIT about a month ago. At the end I added a photo, which again has since been positively identified (thanks again, Alex)

“Finally, this bird was a distance shot. At the time, it looked larger than a bananaquit – more Loggerhead Kingbird-sized. Before I had downloaded the image and could see it clearly [rather than on the screen on the back of the camera], I’d wondered about a mangrove cuckoo. Then I saw at once that it didn’t tick the right boxes. So I decided it must just be a huge bananaquit with an orange rather than yellow front. If it’s anything else (a rare hybrid spindalisquit?), please say so!” It is a indeed bananaquit, but in my limited experience I have never seen one with a spindalis-orange front. Can anyone say if that is a common colouring on Abaco, or unusual?
