This breaks up air turbulence and allows them to fly completely silently. For example, the leading edge of their flight feathers is serrated like a breadknife. ![]() Wings: All owls have several characteristics that can be used to differentiate them from other raptors. ![]() When nestlings are around 18 days old, females will leave the nest and males will continue to feed the young. Nests are previously excavated holes usually made by woodpeckers that can be anywhere from 8 to 44 feet off the ground. Mating season starts as early as late January and continues until May. Saw-whets are typically monogamous for the season, finding new mates every year, but if there is a good prey season females will take on more than one male. Because owls do not have a high enough stomach acidity to digest bones, larger owl pellets can easily be dissected to find the skeletons of their most recent prey. The pellet is then regurgitated 10 or more hours later. In the stomach, a pellet (or cast) is formed from the fur, bones, and other indigestible material. They often swallow their food whole or in large chunks, and it goes directly to their stomach. Unlike other raptors, owls have no crop for food storage. They will also eat insects, and during migration saw-whets will supplement their diet with smaller bird species. ![]() Saw-whets usually hunt small rodents from a low perch along the forest edge but can also hunt juveniles of larger mammals such as squirrels or chipmunks.
