Abstract

A previously undescribed population of black-browed albatrosses (Thalassarche melanophrys) is reported at the Evangelistas Islets, Straits of Magellan, Chile. The population was censused from aerial photographs taken on 13 October 2002 that yielded an estimate of the number of breeding pairs. A combined total of 4,670 pairs of black-browed albatrosses were found nesting at Elcano and Lobos Islets, 2 of the 4 islets in the Evangelistas group. This new record raises to four the number of breeding islands of this albatross species in Chile.
