Abstract

A small breeding population of Black Noddy Anous minutus was encountered on San Ambrosio Island in the Desventuradas Archipelago in the southeast Pacific off Chile. On 11 December 2019, we found eight Black Noddy nests among 50–60 nests of Brown Noddies A. stolidus. Black Noddy nests were placed on the ground with little to no nesting material in the interior of the island, which is an unusual nest type and placement for this species. All nests were at different stages, from recently hatched to recently fledged nestlings. Black Noddies usually nest in trees or bushes, but the vegetation on San Ambrosio had been largely extirpated, raising the possibility that this small population may have been larger prior to habitat loss. This is the first published documented record of Black Noddies in Chile and is the southeasternmost breeding population of this species in the Pacific.
