Comportamiento de vuelo del Aguilucho Común (Buteo polyosoma) durante el verano en Nevados de Chillán, Chile
Resumen
Describimos los tipos de vuelo del Aguilucho Común (Buteo polyosoma) durante el verano en Nevados de Chillán, Chile. Los tipos de vuelo usados más a menudo fueron el vuelo planeado, el vuelo estacionario y el vuelo circular encumbrado (36.7%, 29.4% y 27.8% del tiempo de vuelo total, respectivamente). El tiempo invertido en el vuelo planeado y el vuelo estacionario fue máximo durante la media tarde (17:00–19:00 h). Por el contrario, la cantidad de tiempo invertido en el vuelo circular encumbrado fue mayor entre la media mañana (10:00–11:00 h) y el mediodía (13:00–14:00 h). Los aguiluchos parecieron usar estos tipos de vuelo de una manera oportunista, tomando provecho de las ventajas microclimáticas y las condiciones topográficas.
