immature (left in A, B, left in C, D, left in A, top in F) and
second-year (possibly advanced first-year?) immature (right in C, right
in E, G) with Laughing Gulls (L. atricilla; centre in A, centre in E, bottom in G), adult Kelp Gull (L. dominicanus; right in A, middle in F) and adult Lesser Black-backed Gull (L. fuscus;
bottom in F) at Waterloo, Trinidad, 10 July 2000. Photos © by Floyd
Hayes. Note the relatively short wings of both birds (which change at
different angles), suggestive of Kelp Gull, the prominent gonys on a
rather thin bill of the first-year immature, and the slate grey wings
and back of the second-year immature. To compare with other photos of
adult Kelp Gull and adult Lesser Black-backed Gull taken at the same
time, click here. To see the opinions of others, click here.
