Comentários
Gray underparts help to distinguish this species from Forster's Tern (which shows all white underparts).
Detalhes da observação
This adult bird was the only small Sterna tern standing on the beach with Caspian Terns. It was gray (rather than white like on Forster's Tern) below, its black-tipped bill was more red than orange, and it had a white tail with dark outer web of the outer rectices (rather than a gray tail with white outer webs of the outer rectrices like on Forster's Tern).
