Glaucidium minutissimum
The East Brazilian Pygmy Owl (*Glaucidium minutissimum*) is a remarkably small and charismatic raptor, endemic to the fragmented Atlantic Forest biome of eastern Brazil. Measuring just 13-15 cm in length and weighing around 40-59 grams, it is one of the smallest owls in the Americas, easily distinguished by its rufous-brown to grayish-brown upperparts, finely spotted with white, and paler, heavily streaked underparts. Key field marks include prominent white eyebrows, bright yellow irises, and...
This pygmy owl primarily inhabits the humid, evergreen forests of the Atlantic Forest biome, favoring both primary and mature secondary growth. It is typically found from lowlands up to elevations of about 1200 meters, preferring dense canopy cover.
Its diet primarily consists of large insects such as beetles, moths, and cicadas, but it also preys on a variety of small vertebrates, including small birds, lizards, and small rodents, often ambushing them from a perch.

It employs a classic sit-and-wait foraging strategy, perching inconspicuously before making...
The East Brazilian Pygmy Owl is strictly endemic to the Atlantic Forest biome along the eastern coast of Brazil, ranging from the state of Alagoas (and possibly Pernambuco) in the northeast, southward through Bahia, Espírito Santo, Minas Gerais, Rio de Janeiro, São Paulo, Paraná, and extending to...
