Like the osprey, the barn owl (Tyto alba) is found on all continents except Antarctica. It prefers to live near grassy fields and meadows, where it hunts mice, bats and even skunks. Its white face is framed by a heart-shaped facial disk, and its tawny body is flecked with small black-and-white spots. The barn owl doesn't make the expected "hoot" sound, instead producing a high-pitched scream that sounds like a screeching cat.
German scientists are using an eight-camera device to record the flight movements and changing wing shape of Happy, one of a pair of barn owls at RTWH Aachen University being studied.

Boreal owls, like this one shown in Manitoba, Canada, often sit on perches, listening for any scurrying rodents below. Then they dive down to capture a meaty meal.
A baby barred owl usually fledges at about 45 days old. Once mature, barred owls can weigh up to 1.5 pounds (680 grams) with wingspans of 50 inches (130 centimeters).
Snowy owls, like Harry Potter's Hedwig, have wingspans of about 5 feet and they are known to swallow prey, such as lemmings, whole.
