Little White Tern

The little white tern is much smaller and has a more slender bill than any subspecies of the common white tern. It has been described as a "compact, goggle-eyed bird with shorter, more rounded wings and less deeply forked tail" when compared to Gygis alba. The calamus or 'quill' of the feather in the little white tern are notably white compared to black calamus found in common white terns.
