Taxonomy

The species Attila bolivianus was first described by French ornithologist Frédéric de Lafresnaye in 1848.[3] There are two subspecies of Attila bolivianus recognized by the International Ornithological Committee and the Clements checklist:[1][4]

Description

The white-eyed attila measures around 19–22 cm (7.5–8.7 in) and weighs 40–45 g (1.4–1.6 oz).[5] It has striking pale yellow-white eyes

Distribution

In Peru, the white-eyed attila is widespread in the eastern low-laying areas, generally south of the Amazon River.[6]

Behavior

The white-eyed attila generally preys on arthropods and sometimes eats fruit. It perches and scans its surroundings outward, usually from a well-lit area. When it finds its food, it rapidly flies toward it and snatches it off the surface it was on, or it may engage in hover-gleaning, first hovering then glean its prey from foliage.[5][7]

Etymology

The specific and subspecific names "bolivianus" are named for Bolivia. Its subspecific name "nattereri" is named for the Austrian naturalist Johann Natterer.[5]
