Atlantic White Tern

Gygis alba

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The white tern, or fairy tern, is an entirely white seabird with a blue-black bill and huge eyes ringed in dark that give it an unmistakable expression. It lives on tropical islands throughout the oceans and has one of the most reckless nesting strategies in the animal kingdom: it builds no nest and balances its single egg on a bare branch, a fork or a ledge.

Fun facts

  • It makes no nest: it lays the egg balanced directly on a bare branch, and many are lost to the wind. The chick hatches with disproportionately large claws that let it grip the bark from its first day.
  • It is the official city bird of Honolulu, where an urban colony nests in the street trees and where it is protected by municipal ordinance.
