About These Birds

Boreal Owl

The Boreal Owl (<em>Aegolius funereus</em>) is a small owl belonging to the family Strigidae (True Owls). It inhabits forest environments, where it relies on dense coniferous and mixed woodland cover for shelter and foraging. Detailed plumage and behavioral descriptions of this species are limited in the available literature. The Boreal Owl nests in cavities (nest type CV), making use of natural tree hollows or abandoned woodpecker holes. Incubation lasts approximately 29 days, and fledging occurs between 28 and 36 days …

Eurasian Eagle-Owl

The Eurasian eagle-owl is one of the largest owl species in the world, with females sometimes reaching a wingspan of nearly two meters. Its deep booming call can be heard up to four kilometers away on calm nights. These apex predators sit at the top of the avian food chain, preying on other raptors including buzzards and smaller owls.
