|East Brazilian pygmy owl|
It has been argued that the here used scientific name actually belongs to the Pernambuco pygmy owl, in which case the East Brazilian pygmy owl should be referred to G. sicki (König & Weick, 2005). This has not gained widespread recognition.
It inhabits tropical and subtropical moist evergreen forests and edges as well as open bush canopy.
It is one of the smallest South American owls, averaging at 55 grams (1.9 oz) and 15 cm (6 in). Wing length can reach 85–91 millimetres (3.3–3.6 in), while the tail can reach a length of 49–54 millimetres (1.9–2.1 in). The head is rounded, with no ear tufts. The pale greyish-brown facial disk is not pronounced and shows some rufous concentric lines. The eyes are yellow, with whitish eyebrows. The upper part of the body is relatively dark, rufous-brown with small white spots. Wings are dark brown and relatively short. The tail is dark brown with five pale bars. The lower part of the body is light gray or white, with reddish-brown stripes. The throat shows a rounded whitish area. The legs are feathered, with bristled and yellowish toes. Claws are horn with dark tips. The beak is yellow-green.
The East Brazilian pygmy owl mainly feeds on small insects and sometimes catch small vertebrates. It is active at dusk and dawn, but occasionally hunts during the day. Song of the male is two-four long notes separated by short pauses.
