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.
