Selective consumption of rodents by the Variable hawk Geranoaetus polyosoma (Accipitriformes: Accipitridae) in the Atacama Desert, northern Chile
ABSTRACT Geranoaetus polyosoma (Quoy & Gaimard, 1824) is a diurnal raptor widely distributed in South America. Although the trophic ecology of this bird has been more studied in the southern extreme of its range, little information is available on its dietary response to prey supply in desert en...
