Like many parts of the body, the brain tends to shrink with age, but lifting weights appears to help slow the process.
They usually build their nests about as high up as the roof of a one-floor house. A mother Screech Owl will lay 3 or 4 eggs in their nests, and will sit on them for about 26 days, until the baby owls hatch. What they eat: Screech Owls hunt for food at night, when they can see much better than people can. Most owls look for food from a tree branch, but screech owls hunt while they fly around. When they find food, they fly down very, very quietly and catch it. Then they take the food up into a tree and tear it to bits and eat it. Screech owls like to eat little birds, mice, shrews, and other small animals.
Barn Owls eat mostly small mammals, particularly rats, mice, voles, lemmings, and other rodents; also shrews, bats, and rabbits. Most of the prey they eat are active at night, so squirrels and chipmunks are relatively safe from Barn Owls. They occasionally eat birds such as starlings, blackbirds, and meadowlarks. Nesting Barn Owls sometimes store dozens of prey items at the nest site while they are incubating to feed the young once they hatch.
