ANTILLEAN NIGHTHAWKS REVISITED

In 2014 I wrote about finding myself – with others on a birding expedition – in the midst of dozens of nighthawks as they swooped and dived (dove?) while hawking for flies. “The birds were quite unperturbed by our presence, and from time to time would zoom past within inches of our heads, making a swooshing noise as they did so”. You can find the post at FAST FOOD ON THE WING.

Nighthawks catch flying insects on the wing, and mostly forage at dawn and dusk – or (more romantically) at night in a full moon.

Besides aerial feeding displays, nighthawks may also be seen on the ground, where they nest. I say ‘nest’, but actually they hardy bother to make an actual nest, but just lay their eggs on bare ground. And, more riskily, this may well be out in the open rather than concealed. The eggs – usually 2 – hatch after 3 weeks or so, and after another 3 weeks the chicks fledge.

Fortunately their colouring enables them to blend in with the landscape – a good example of bird camouflage in natural surroundings.

The photos above are from Sandy Walker (header), Stephen Connett – to whom special thanks for use permission for his great nighthawk and egg images – and the last one by bird legend and author of the locus classicus The Birds of the Bahamas (without which no trip to the Bahamas is complete), Bruce Hallett.

Antillean Nighthawk Chordeiles gundlachii, is a species of nightjar. These birds have local names such as ‘killa-ka-dick’, ‘pi-di-mi-dix’, ‘pity-pat-pit’, or variations on the theme, presumably onomatopoeic. Pikadik-(dik) will do for me. See what you reckon from these recordings (excuse the thick-billed vireo – I think – in the background):

ODD FACT

I have read in several sources that no one knows where these migratory birds spend winter; or else that winter season data is ‘scarce’. So no sensible range maps exist, for example. If you read this, and have antillean nighthawks (as opposed to common nighthawks) all round you in winter, please tell someone – you may hold the key to an ornithological mystery…

As so often, the Bahamas Philatelic Bureau leads the way with natural history stamps. The 15c Antillean Nighthawk above featured in a 2001 bird set. You can see dozens more very excellent Bahamas bird, butterfly, fish, flower and other wildlife stamps HERE.

FAST FOOD ON THE WING: ANTILLEAN NIGHTHAWKS ON ABACO

FAST FOOD ON THE WING: ANTILLEAN NIGHTHAWKS ON ABACO

A bird ID query was recently posted on my FB page by Abaco resident Maria Bethel Flore, who said “I saw a flock of birds I’ve never seen before. All black except for a white stripe underneath the wing. I didn’t get one good picture they were flying so fast”. There were a couple of clues there: a fast-flying flock; and the white underwing bars. Maria’s distant image confirmed the ID as an Antillean Nighthawk Chordeiles gundlachii. These birds have local names such as ‘killakadick’ and ‘pi-di-mi-dix’, or variations on the theme – presumably onomatopoeic.

I thought a post illustrating these wonderful birds in flight and on the ground would be timely.

The photos above were taken during a trip into deep South Abaco backcountry to the west of the Highway to photograph birds for BIRDS OF ABACO. We reached an open area late in the afternoon to find ourselves in the middle of dozens of nighthawks swooping and diving as they hawked for flies. We leapt out of the truck (we stopped it first) with eager eyes and cameras and watched the performance in amazement. The birds were quite unperturbed by our presence, and from time to time would zoom past within inches of our heads, making a swooshing noise as they did so.

The speed of flight and the jagging paths made it extremely hard to take photos. Photographer Tom Sheley (below) was able to nail them (see top 2 images); I could barely catch a bird in my jiggling viewfinder, but Sandy Walker got a good clear shot (photo 3).

Apart from the exuberant aerial displays such as I have described, nighthawks may also be seen on the ground, where they nest. Their colouring enables them tend to blend in with the surroundings. Woody Bracey took the first 2 pictures; the next is from the excellent BIRDS CARIBBEAN, which anyone with an interest in birds would enjoy; and the final one was scooped by Susan Daughtrey on a recent visit to Abaco – another very good example of the bird’s camouflage in natural surroundings.

ABACO: THE PERFECT PLACE FOR BAHAMAS BIRDING

ABACO: THE PERFECT PLACE FOR BAHAMAS BIRDING

I’ve ~~fairly~~ very often mentioned the remarkable diversity of the bird species on Abaco. This small island has a wide variety of permanent resident species and the advantage of being on a primary migration route so that it has both winter and summer migratory visitors. Here’s an example of some of the species a visitor might reasonably expect to find during a day’s birding. This isn’t an ‘invented inventory’, easy though that would be to compile. It records a birding outing by Abaco visitor Susan Daughtrey, guided by the legendary Woody Bracey, with sightings of 53 species from A (baco Parrot) to Z (enaida Dove). Here are some of Susan’s photos of the birds she encountered. At the end is the full list of the 34 species she photographed.There’s nothing very rare – most of those shown are permanent residents (PR), breed on Abaco (B) and are commonly found (1). Hence the code* PR B 1. SR is for the 2 summer residents, I is for the introduced collared dove. The best ‘get’ is the Bahama Mockingbird (PR B 3), a bird mainly of the pine forests and not so easy to find.

ADDENDUM Susan has now sent me her complete record for a great day out in which 53 species were seen. The list shows the numbers seen for each species. I have had to reformat the list from the original to make it work in this blog. I have added links for the first bird, the Black-bellied Whistling Duck, which was recorded on Abaco for the first time in early June. Of the six seen at any one time to begin with (including at Delphi), the reported numbers dropped to 2, then 1. The latest news is an unconfirmed sighting of a single bird at Treasure Cay Golf Course.

ABACO: A SANDY ISLAND (SANDY BEACHES, A SANDY POINT & A SANDY WALKER)

ABACO: A SANDY ISLAND (SANDY BEACHES, A SANDY POINT AND A SANDY WALKER)

This post features some great Abaco bird photos taken by Sandy Walker, a man familiar to anyone connected with the Delphi Club in any capacity at all, and well-known far and wide from Marsh Harbour to Ireland. Possibly notorious in some places… Sandy doesn’t talk about his photography much, though he has plenty to say on most topics. Here are a few of his photos taken in the last 6 months or so, and deserving a wider audience. The header image, from the Delphi garden, shows a Bananaquit in characteristic feeding mode.

CUBAN PEWEES

A great picture of feeding time, with the huge chick already seeming to have outgrown the parent – apart from its rather stumpy tail

CLAPPER RAIL

These shy birds are reclusive by nature and relatively hard to photograph. They tend to lurk in the undergrowth or half-hidden on water margins. If they are caught in the open, they tend to run in a somewhat cartoonish sort of way. This one was having a good dig in the mud for food.

WILLET

Large birds of the shoreline and mangrove swamps, and classed with sandpipers. In flight, they have eye-catching wing stripes that Sandy has captured with a bit of camera sharp-shooting. You can see more Willets HERE

ANTILLEAN NIGHTHAWK

I was with Sandy when he took this photo during an amazing early evening feeding display of these birds. A hundred or more were swooping and jinking, making the most of an evening fly hatch. Sometimes they flew very close to our heads, make a whirring sound as they passed. Their speed and jagging flight made them very hard to take. I hardly got one in my viewfinder at all, but Sandy is an excellent shot of a different sort, so I guess aiming isn’t a problem for him…

SNOWY EGRET

I love these handsome birds, distinguishable from all other white herons and egrets (in some cases as white morphs) by their astonishing bright yellow feet. These are so vivid that they are often clearly visible when a snowy egret is standing in the water. This one was taken by the jetty at a local pond, a wonderful and secluded place to see water birds of many varieties, including rarities.

PHOTOGENIC ENDEMICS: BAHAMA YELLOWTHROATS ON ABACO

PHOTOGENIC ENDEMICS: BAHAMA YELLOWTHROATS ON ABACO

I’ve been keeping this little bird up my capacious avian-friendly sleeve for a while. In June we took a truck and headed for deep backcountry to the edge of the pine forests and beyond to see what we could find in the way of birdlife. Good choice – the answer was ‘plenty’.

Among the birds we encountered were the endemic Bahama swallows, hairy woodpeckers, red-tailed hawks, kingbirds, red-legged thrushes, red-winged blackbirds, western spindalises, tobacco doves, La Sagra’s flycatchers, crescent-eyed pewees with a nest and eggs, a wonderful ‘booming display’ by antillean nighthawks courting during an early evening fly hatch**… and Bahama yellowthroats Geothlypis rostrata.

The illustrative photos are of poor quality, but rather than blame my camera (as I am only too ready to do), I plead ‘overexcitement’ in mitigation. Of the 4 endemic species on Abaco, this was the only one I’d never seen. There was a tweeting noise on the edge of an abandoned sugar cane field (above), followed by some rustling… and out fluttered this bird, crossing the track right by us and landing quite close to inspect us.

This striking bird, with its Zorro mask and bright yellow body, is an endearing mix of shy and inquisitive. Only the males have the mask – the females are less colourful, though naturally equally interesting…

Yellowthroats are responsive to pishing, and once lured from cover they may happily remain on low-to-medium height branches or on a shrub, watching you watching them.

Their song is quite easily imitated, and that may also bring them into the open – a source of immense satisfaction to the amateur (me) if it works. Here’s an example, courtesy of my iPH@NE METHOD for bird recording. It’s the call at the start and the end.

The one we watched had plenty to sing about – it’s just a shame that my images are so poor, because in some you can see its tiny tongue. A bit too blurry, though, even by my own moderate standards for inclusion.

At a formative stage of this blog, I did a short post about the endemic Bahama Yellowthroat and its comparisons with the similar and better-known Common Yellowthroat, which is also found in the Bahamas. You can read it HERE. There’s a female shown, a video, and an unacknowledged debt to Wiki or similar source, I can’t help but notice…

**ANTILLEAN NIGHTHAWKS AND THE ‘BOOMING DISPLAY’

Common Nighthawk Photo “On summer evenings, keep an eye and an ear out for the male Nighthawk’s dramatic “booming” display flight. Flying at a height slightly above the treetops, he abruptly dives for the ground. As he peels out of his dive (sometimes just a few meters from the ground) he flexes his wings downward, and the air rushing across his wingtips makes a deep booming or whooshing sound, as if a racecar has just passed by. The dives may be directed at females, territorial intruders, and even people.” We found ourselves right in the middle of one of these astounding displays, with maybe 100 birds behaving exactly as described, often whooshing within inches of our heads. I’ll post some more about it in due course. Credits: Philip Simmons; All About Birds (Cornell Lab)
