Thalasseus bernsteini (Chinese Crested Tern)

Synonyms: Sterna bernsteini; Sterna zimmermanni

Wikipedia Abstract

The Chinese crested tern (Thalasseus bernsteini) is a seabird of the tern family, Sternidae, closely related to the Sandwich tern, T. sandvicensis, and the lesser crested tern, T. bengalensis. It is most similar to the former, differing only in the bill pattern, which is the reverse of the Sandwich tern's, being yellow with a black tip. From the lesser crested tern, which it overlaps in wintering distribution, it can be told by the white rump and paler grey mantle, as well as the black tip to the bill, which seen from up close also has a white point. The larger greater crested tern is also similar, differing in its stouter, all-yellow bill and darker grey mantle and rump, as well as in size.
