About These Birds
Buff-fronted Owl
The Buff-fronted Owl (<em>Aegolius harrisii</em>) is a small owl in the family Strigidae (True Owls). It is associated with forest habitats, where it likely occupies dense woodland or forest-edge environments. Detailed plumage and behavioral descriptions of this species are limited in the available literature. Like other members of its genus, the Buff-fronted Owl is a cavity nester (nest type CV), using natural hollows or abandoned woodpecker excavations for breeding. Clutch size is recorded as 3 eggs. Song and call descriptions …
Snowy Owl
The snowy owl is the heaviest North American owl and one of the most charismatic Arctic birds. Unlike most owls, it is largely diurnal, necessitated by the continuous daylight of Arctic summers. Snowy owl irruptions — periodic mass southward movements — are tied to lemming population cycles.
