About These Birds
African Scops-owl
The African Scops-owl is a small, cryptically patterned owl with a wingspan of about 26 cm and a weight near 88 g. It roosts by day pressed against tree bark, blending in perfectly, and calls at night with a repetitive, monotone whistle across African savannas and woodlands.
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.
