Glaucidium perlatum (Pearl-spotted Owlet)

Synonyms: Strix perlata

Wikipedia Abstract

The pearl-spotted owlet (Glaucidium perlatum) is an owl that breeds in Africa south of the Sahara. This species is a part of the larger grouping of owls known as typical owls, Strigidae, which contains most species of owl. The other grouping is the barn owls, Tytonidae. The pearl-spotted owlet is a common and easily seen bird in open woodland and savannah. It nests in a hole in a tree, such as a disused barbet nest, laying 2-4 eggs. Sexes are similar, but young birds are paler with a shorter tail. The flight is deeply undulating.
