About These Birds
Arabian Scops-owl
The Arabian Scops-owl is a small nocturnal owl from the Arabian Peninsula, weighing about 66.5 grams with a wingspan near 25 cm. It inhabits rocky wadis, date palm groves, and dry woodland, where it hunts insects and small vertebrates at night. Its cryptic streaked plumage makes it nearly invisible when roosting against tree bark or rocky surfaces during the day.
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.
