There are 28 Longbills in this photo, some partly hidden behind the mangroves.
Détails de l'observation
These birds have been observed and photographed now in great detail. Dark feather centers, dark chin, neck and chest providing clean contrast with white bellies, heavy barring, not spotting, on flanks, some with excessively long bills, much wider black bars than white ones on tail feathers, low forehead angle, with facial expression different from Short-billed Dowitchers. Also "hunched" rounded backs and 'egg-shaped' bodies, with noticeable 'valley' between back and tail feathers, also 'weight-forward' look, all attest to these birds being L-b Ds. When there is a call, it is the high "Keek!" that is diagnostic of Long-billed Dowitchers. Some birds' bills, measured from photographs, are exactly twice the head length. The bills are all pencil-straight, without the diagnostic one-third droop of their cousins the S-bs, and without the slightly flattened, blunt ends that Short-billed Dowitchers typically exhibit. It is my very best opinion that this entire flock is made up of Long-billed Dowitchers.
