WHITE-TAILED TROPICBIRDS

EFFORTLESS ELEGANCE

Here are some gorgeous white-tailed tropicbirds (Phaethon lepturus catesbyi) seen within the last week near the Low Place on Man-o-War Cay. There were 6 in the group, flying high, flying low, circling, dipping down, flirting  – all of this taking place just offshore.

Sally Chisholm, Abaco birder and photographer, was with Todd Pover of CWFNJ, engaged in the final piping plover count of the season before the birds return to their summer breeding grounds [check out ABACO PIPING PLOVER WATCH if you are interested]. Sally and Todd were distracted from the matter in hand as the group of tropicbirds glided and swooped through the air. It was a free demonstration of beautiful flying skills that can be matched by few other species.

It became obvious that courtship was involved. As Sally vividly describes it, “The birds were observed for more than 15 minutes making wide circles, at times flying out of sight across towards Great Abaco and coming back flying low over the same area on MOW. Two birds would interact with a lot of “keck-keck-keck”, and then one of the pair flew down to land several times in the same crevice of the iron shore. It first appeared that the bird was landing for food but none of the photos showed anything carried. The display looked to be one of courtship and was amazing to watch”.

TROPICAL TOPICS

  • WTTR plunge-dive for fish and squid, sometimes submerging completely
  • Or they swoop and skim their prey from the surface
  • Another technique to take flying fish in the air (I’d love to see that…)
  • WTTR have no fixed breeding season, and may nest year-round
  • Nesting is colonial or in pairs in a particular area, or even in isolation
  • Pre-mating behaviour involves courtship displays (as here)
  • A pair will fly together, one above the other then…
  • …the higher bird bends its tail down to touch tail of lower bird and [veil drawn]
  • They nest in crevices, holes in rock, on ledges, on the ground under vegetation
  • Chicks are fed by both parents using regurgitation
  • The same site may be re-used for several years by the same pair

SANDHILL CRANE: NEW BIRD FOR ABACO

Sandhill Crane Antigone canadensis Abaco, Bahamas (Christopher Johnson) SANDHILL CRANE: ABACO’S NOVELTY BIRD (2)

In mid-December, Kaderin Mills of the Bahamas National Trust saw Abaco’s first-ever reported Sandhill Crane (Antigone canadensis) in the Fox Town area of North Abaco. Woody Bracey was quickly onto the news and in the afternoon he took photos of the bird. I posted about this exciting (because a new species is always exciting) event, with details about its significance plus facts, maps etc HERE

Six weeks later, the crane is still in residence. In the meantime a number of birders have been to see the new novelty bird for Abaco in what has become a small but significant birding hotspot right at the top end of the island, in area round the Church, the Primary School, and the Clinic. The crane is now firmly on the eBird map for the Bahamas.

This elegant visitor seems to be quite tame and unfazed by its new fame. People watch while it forages for invertebrates in the grass, pausing to check on bystanders before resuming its feeding. It tolerates the presence of humans without showing fear, let alone flying away.

The call of the Sandhill Crane sounds like this:

To test its reaction, a recording was played and immediately the crane responded and called out to the (apparent) co-crane. The bird has also (rather sadly?) been seen by locals by the door of the Church, looking at its reflection and even making pecking motions at it. A lonely crane, maybe.

This bird is likely to remain disappointed by any expectation or hope of company. With any luck in the Spring, the instinctive call to the north (Canada and nearby US) will persuade it to migrate back to sandhill habitat to join a flock in the summer breeding grounds.

It is always a somewhat melancholy occurrence when a fine bird like this – or like last season’s lone BALD EAGLE – takes a wrong turn on their migration or perhaps get blown off course and finds itself on its own, species-wise. This bird seems to be taking it in its (longish) stride, however, and it has become something of a celebrity avian for the local folk. It will be interesting to find out when the migration urge finally encourages its flight away from its unusual overwintering habitat.
