Description: |
Booby shape (pointed at both ends). Size
hard to judge, since I'm not accustomed to seeing sulids up close, but
appeared small. In one still grabbed from the video, a Caspian Tern appears
to be approximately 2/3 the size of the booby. Long, narrow wings had
swept-back look when bird was gliding. Underside of wings was dark brown.
Upper surface of wings showed dark brown flight feathers contrasting with
paler brown coverts. Head, neck, and underparts were whitish, with a little
golden/brownish coloration showing on the head and neck in some shots. Back
was brown contrasting with whitish neck. Bill appears to be pale grayish in
video. Tail appeared brown from above and below. Primaries showed wear and
possible molt. |
Voice: |
None |
Similar
species: |
Contrast of upperwing pattern and all dark
underwing indicate this species. Bill color on Dittmann photo shows
diagnostic grayish bill color with pink tones at the base. |
