About the Peruvian Tern

The Peruvian tern (Sternula lorata) is a species of tern in the family Laridae. Found in northern Chile, Ecuador, and Peru, its natural habitats are hot deserts, sandy shores, and coastal saline lagoons. It is threatened by habitat loss.

In Spanish, it is known as the "charrancito Peruano" or "gaviotín chico". The Peruvian tern is a very small species with a length of about 24 cm (9.4 in). The upper half of the head and neck are black, and the remaining part of the head is white. The back, wings and tail are grey, the throat, chin and breast are white, and the chest, belly and flanks are pale grey. The under tail-coverts are white. The bill is yellow with a black tip, the irises are brown and the legs are yellowish. The pale grey underparts differentiate it from other small terns. It has a very rapid and characteristic wingbeat. The call is a shrill "kik" and a harsh "gree", and it also utters a descending series of "kee-ee-eer" notes.

This species is endemic to the tropical west coast of South America. Its range extends from north and central Ecuador, through Peru to northern Chile, as far south as the Mejillones Peninsula. Its status in Ecuador... Wikipedia →
