Chinese Crested Tern

The Chinese crested tern (Thalasseus bernsteini) is a rare tern in the family Laridae. It is 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. The Chinese Crested Tern is one of the rarest birds in the world; the total population is reported to be fewer than 50 birds. It is a critically endangered species and was previously thought to be extinct.
