Black-fronted Tern

This species is sometimes considered to belong to the genus Sterna (Sterna albostriata). Quite similar to the Whiskered Tern (Chlidonias hybridus). Upperparts and back uniformly dark grey, white rump (grey in Whiskered Tern), outer rectrices pale grey. Black forehead extending from the bill to the nape, just beneath the eye. White cheeks contrasting with the grey throat and flanks, as well as the belly and breast. Bill and legs reddish. Legs are short. Forked tail. In non-breeding adults, the forehead is much paler and only extends from one eye to the other, and the bill tip is black.Juveniles are quite similar, but the bill is more of a dull orange than red, and the black extends further onto the tip.
