Is essentially a sea bird, being seldom found inland except some short way up the larger rivers. It feeds on small fish and insects of various kinds. For breeding purposes it selects a sand-bank or the dry portions of a marsh or an island in a lagoon, where it nests in colonies. I found it nesting in May in the marismas of the Guadalquivir, on the dried mud of an island in the lagoon, constructing a somewhat loosely built nest of sticks and a few Flamingoes’ feathers, the number of eggs being 3, sometimes only 2. These were white in ground-colour, with a faint rosy blush when fresh, with pale inky grey shell-markings and black or blackish brown surface spots and blotches, some being only sparingly marked, whereas others are very boldly and profusely blotched, chiefly at the larger end. In size they measure about 2.95 by 1.53.
