The crane hawk (Geranospiza caerulescens) is a species of bird of prey in the Accipitridae family. It is monotypic within the genus Geranospiza.[2] It is found in Argentina, Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname, Uruguay, and Venezuela. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, and subtropical or tropical swamps.[2]

In flight

The crane hawk has very long legs which it uses to extract prey from crevices in trees.[3] It can pull tree frogs from inside bromeliads and nestlings from tree holes.[3][4] As an example of convergent evolution, it is very similar to the Afrotropic harrier-hawks (genus Polyboroides).[4]
