The Gelbbrauenkauz ( Pulsatrix koeniswaldiana ), also Koeniswald-owl or white-throated Spectacled called, is an owl art from the family of authentics owl (Strigidae). It occurs exclusively in South America.
Appearance
The yellow-eyed owl reaches a body length of 44 centimeters and is a medium-sized representative within the genus of the owls. The eyebrows are yellowish-brown and the eyes are maroon. There is a large white spot on the chin. As is typical for eyeglasses, a broad brown band runs across the chest, which in some individuals can be interrupted in the middle. The rest of the underside of the body is yellowish-cinnamon in color. The legs are feathered, the toes are bare.
The yellow-eyed owl can be confused with several other owls. Both the Spectacled and the short-browed Spectacled are slightly larger and reach body lengths of up to 52 centimeters. The owl has showy white eyebrows; The short-browed owl differs from the yellow-browed owl mainly in its significantly shorter eyebrows and its brown-yellow to dark-yellow eyes. In contrast to the yellow- eyed owl , the brown owl has a whitish belly. All four types differ in their sound repertoire.
Distribution area and habitat
The distribution area of the yellow-eyed owl extends from the east of Brazil to the northeast of Argentina. It is probably a resident bird and inhabits tropical and subtropical forests with old trees. Often these are interspersed with conifers such as Araucaria angustifolia . It occurs at altitudes up to 1,500 meters above sea level.
Way of life
The yellow-eyed owl is a nocturnal species of owl. He usually transmits sitting alone in trees. Its food spectrum consists of small mammals and birds. But it also beats other small vertebrates and larger insects. He uses tree hollows as a nesting place. The clutch usually consists of two white eggs that are incubated by the female alone. The male provides the female with food during this time. The young birds fledge at around five to six weeks. They are looked after by the parent birds for several months.
