Owls are known for their disproportionally large eyes in comparison to their skulls.
Long-eared owls are usually strictly nocturnal birds. Long-eared owls are more or less strictly nocturnal in activity. Usually activity for the species commences at dusk. [8] After nightfall long-eared owls in Idaho were least active from 8-10 pm and from 5-6 am, while the hours around 10-12 pm and 3-5 am were often the peak times of activity. [90]
Tawny frogmouths and owls both have mottled patterns, wide eyes and anisodactyl feet. However, owls are birds of prey who possess strong legs, powerful talons, and toes with a unique flexible joint they use to catch prey. [2] Tawny frogmouths are insectivores who prefer to catch their prey with their beaks and have fairly weak feet. [4]
In most aspects of their behavior, great horned owls are typical of owls and most birds of prey. Like most owls, the great horned owl makes great use of secrecy and stealth. Due to its natural-colored plumage, it is well camouflaged both while active at night and while roosting during the day.
