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. |
Resumo em outra língua: | Se carece de estudios sobre comportamiento territorial y cortejo de muchas rapaces tropicales. De 2006 a 2009, utilizando observaciones ad libitum, estudiamos los comportamientos territoriales y de cortejo de Buteogallus lacernulatus y Pseudastur polionotus en el Parque Estatal Rio Doce en el este de Brasil. Observamos individuos de B. lacernulatus y P. polionotus involucrados en exhibiciones aéreas en 67 y 13 ocasiones, respectivamente. Los comportamientos de exhibición realizados por B. lacernulatus se caracterizaron por una a cuatro ondulaciones seguidas de lanzamientos aéreos y espirales. Los comportamientos territoriales y/o de cortejo de P. polionotus se caracterizaron por planeos térmicos u horizontales del macho y la hembra juntos e inmersiones en espiral mientras emitıan con frecuencia una serie de silbidos largos y cortos. Este estudio presenta las primeras descripciones formales de las exhibiciones aéreas territoriales y de cortejo de estas raras rapaces que habitan en los bosques. |
