Lesser Noddy

Anous tenuirostris

A small dark tern which appears grayish-black and extremely slender. Very similar to Black and Brown Noddies, but the Lesser Noddy has a very thin bill, is somewhat paler gray overall, and has gray between the bill and the eyes. The flight is fast and graceful, and it often mixes with other terns. Often found offshore, not far from islands in the tropical waters of the Indian Ocean.

分类信息

The first formal description of the lesser noddy was by the Dutch zoologist Coenraad Jacob Temminck in 1823 under the binomial name Sterna tenuirostris. The genus Anous was introduced by the English naturalist James Francis Stephens in 1826. Anous is Ancient Greek for "stupid" or "foolish". The specific name tenuirostris is from the Latin tenuis for "slender" and -rostris "-billed".<p>There are two subspecies:
