New nesting locality of the Agami Heron, Agamia agami (Pelecaniformes: Ardeidae) in Ecuador

Abstract

The Agami heron, Agamia agami , is a rare species of the Neotropics, and even though its distribution is large, little is known about the sites where it congregates to nest. We report a new nesting site, which is the eighth reported site in the Neotropics, located in Tambococha, Yasuni National Park, Ecuador. We estimate that it is occupied by approximately 140 individuals, based on the 70 nests counted and considering the monogamous behavior of this species for at least one year. The discovery of this nesting colony is important to determine more precisely the distribution area of this species, and, in the future, monitor populations and develop studies of population genetics, migration, and behavioral movements as a basis to implement a conservation strategy for the Agami Heron in Ecuador.
