Territorial behavior of the white-necked hawk (Buteogallus lacernulatus) and the mantled hawk (Pseudastur polionotus) in eastern Brazil.

Resumo
Studies of territorial and courtship behavior are lacking for many tropical raptors. From 2006 to 2009, using observations that were not time-limited, we studied the territorial and courtship behaviors of the White-necked Hawk (Buteogallus lacernulatus) and the Mantled Hawk (Pseudastur polionotus) in Rio Doce State Park in eastern Brazil. We observed White-necked Hawks and Mantled Hawks engaged in aerial displays on 67 and 13 occasions, respectively. Display behaviors performed by White-necked Hawks were characterized by 1–4 undulations followed by aerial swoops and spirals. Territorial and/or courtship behaviors of Mantled Hawks were characterized by the male and female performing thermal or horizontal gliding together and diving in spirals while frequently emitting a series of long and short whistles. This study presents the first formal descriptions of the aerial territorial/courtship displays of these rare forest- dwelling raptors.
