The Peruvian pygmy owl ( Glaucidium peruanum ) is a small species of pygmy owl . It occurs exclusively in South America.
Appearance
The Peruvian pygmy owl reaches a body size of about 15 to 17 centimeters. Feather ears are missing. There are three color morphs that have gray, brown or red-brown plumage. The gray color morph is more likely to be found at higher altitudes. The top of her head is dense white speckles. The morphs, which are more likely to occur in lower mountain ranges, have teardrop-shaped spots or short longitudinal stripes on the top of the head. Like all pygmy owl species, the Peruvian pygmy owl has an occipital face on the neck.
In the range of the Peruvian pygmy owl, there are several other pygmy owl species with which the Peruvian pygmy owl can be confused. It is very similar to the Brazilian pygmy owl and the Yungas pygmy owl . In contrast to the Peruvian pygmy owl, the Brazilian pygmy owl lacks the ocher-colored neck band below the occipital face. The Yungas pygmy owl has rounded wing tips and the drop distribution in the pattern of the head plumage differs from that of the Peruvian pygmy owl. However, the clearest distinction is based on the voice.
Distribution area and habitat
The distribution area of the Peruvian pygmy owl extends from western Ecuador over the west and southwest of Peru to Chile. It is a resident bird that inhabits semi-arid bushland and dry to semi-arid forests. Its height distribution ranges from sea level to altitudes of 3,000 meters above sea level.
Way of life
Like many other pygmy owl species, the Peruvian pygmy owl is partly diurnal. Occasionally, he even sits in exposed waiting areas during the day. Its food spectrum consists mainly of insects and small birds. But it also eats small mammals and other small vertebrates. The males are distinctly territorial and defend their territory vigorously. Abandoned woodpecker holes in trees are used as nesting sites. The female breeds alone.
