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

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.
