Long-eared Owl

Asio otus ORDER: STRIGIFORMES FAMILY: STRIGIDAE

IUCN Conservation Status: Least Concern

Long-eared Owls are lanky owls that often seem to wear a surprised expression thanks to long ear tufts that typically point straight up like exclamation marks. These nocturnal hunters roost in dense foliage, where their camouflage makes them hard to find, and forage over grasslands for small mammals. Long-eared Owls are nimble flyers, with hearing so acute they can snatch prey in complete darkness. In spring and summer, listen for their low, breathy hoots and strange barking calls in the night.

Backyard Tips

Long-eared Owls may nest in artificial baskets and open-fronted nest boxes.

Find This Bird

Long-eared Owls are secretive, nocturnal, and superbly camouflaged. One good way to find them is to listen at night in spring and summer for their long, low hoots. During winter these owls often roost in large numbers, and this can make them easier to find. Methodically search pine stands or shelterbelts near grassland or pasture for roosting owls, often close to the tree trunk among dense branches. Also look along the ground for pellets (gray, roughly oval cylinders of regurgitated fur, feathers, and bone). If you find a large number of these, you may be under a roost tree. Long-eared Owl pellets are typically 2-3” long, while pellets of other owls found in such situations are either larger and less elongate (Great Horned Owl) or smaller and rounder (Northern Saw-whet Owl). Also scan the ground and lower branches for extensive whitewash (bird droppings), which can also indicate recent roosting by owls.
