Fun facts about the Owl
An owl's eyes are fixed in their sockets — they cannot move — which is why owls rotate their heads up to 270 degrees. Owls have three eyelids: one for blinking, one for sleeping, and a third called a nictitating membrane for cleaning. Their flight feathers have comb-like serrations that break up turbulence, making them nearly silent hunters. Some owls can hear prey moving under 60 cm of compacted snow.
