Introduction

This account is dedicated to Carlos Guerra-Correa, marine ornithologist, mentor, and pioneer in the study of the Peruvian Tern.

The Peruvian Tern is an endemic and endangered tern from the Humboldt Current zone along the Pacific coast of South America, ranging from central Ecuador to northern Chile. Belonging to the cosmopolitan Sternula genus, it shares this classification with two other allopatric representatives found in the Neotropics: the boreal migrant Least Tern (Sternula antillarum) and the Amazonian resident Yellow-billed Tern (Sternula superciliaris).

This tern typically nests above the tideline, favoring broad beaches or barren, stony deserts situated at considerable distances inland. It feeds primarily on Peruvian anchoveta (Engraulis ringens) and other fishes, as well as krill. It captures food by plunge-diving from heights of up to 10 m.

As a rare and declining species with a small total population size, the Peruvian Tern is threatened by habitat loss, the presence of feral dogs at colonies, and the overexploitation of the Peruvian anchoveta, among other factors.
