About These Birds
Balsas Screech-owl
The Balsas Screech-owl is a small owl found in dry forest and scrub in the Balsas River drainage of southwestern Mexico, weighing about 160.75g with a wingspan of 34.8cm. Like other screech-owls it is nocturnal and hunts insects, small vertebrates, and invertebrates. Its cryptic plumage provides excellent camouflage against tree bark.
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.
