Short-eared Owl
Identifying characteristics
The Short-eared Owl is a medium-sized owl with a wingspan of about 35 to 39 inches. It has short, rounded wings and a stout body. Its distinctive feature is its small, tuftless ears, which are difficult to see due to their short length. The owl has a mottled brown and white plumage, providing excellent camouflage against its surroundings.
Habitat preferences
Short-eared Owls are found in a variety of habitats, including open grasslands, marshes, and agricultural fields. They prefer areas with low vegetation, such as meadows and coastal dunes. These owls are adaptable and can also be found in tundra and desert environments.
Unique behaviors
One unique behavior of the Short-eared Owl is its diurnal hunting habit. Unlike most owls that are active during the night, the Short-eared Owl hunts primarily during the day. It can often be seen flying low and hovering over its hunting grounds, looking for small mammals such as mice and voles. This owl also performs an impressive sky dance display during courtship, soaring and diving with a combination of slow wingbeats and glides.
Vocalizations
Short-eared Owls are generally silent birds, but during the breeding season, they may produce deep hooting calls or soft barks. The male’s call is low-pitched and repeated at regular intervals, while the female’s call is higher and more varied. These vocalizations are used for courtship and territorial communication.
Mating behaviors
Short-eared Owls are monogamous and form pair bonds that last throughout the breeding season. The male performs aerial displays, including soaring and diving flights, to attract a mate. After mating, the female will lay a clutch of 4 to 7 eggs in a nest on the ground. Both parents take turns incubating the eggs, which hatch after approximately 28 days. The young owls leave the nest after about 3 weeks but remain dependent on their parents for several more weeks.
Long-eared Owl

The owl has a streaked dark brown plumage with buff and white underparts. Its rounded wings and slender body give it an elegant appearance.
Habitat preferences
Long-eared Owls prefer dense coniferous or deciduous forests as their primary habitat. They can also be found in woodlands, parks, and gardens with large trees. These owls rely on dense vegetation for nesting and roosting purposes, often choosing dense stands or thickets for shelter.
Unique behaviors
One unique behavior of the Long-eared Owl is its roosting behavior. During the day, these owls roost together in groups, known as “roosting congregations.” These congregations can consist of several individuals and are often found in dense trees or shrubs. Roosting together provides safety in numbers and also helps conserve body heat during colder months.
Vocalizations
The Long-eared Owl is known for its distinctive vocalizations. It produces a variety of calls, including a low, repetitive hooting sound, often described as a deep “hoo-hoo.” These calls are heard primarily during the breeding season and can carry over long distances. The owl also uses soft, muffled hisses and clucks as territorial calls or alarm signals.
Mating behaviors
Long-eared Owls are typically monogamous and form pair bonds that last for a single breeding season. The male performs courtship displays, such as wing-spreading and bowing, to attract a mate. After mating, the female will lay a clutch of 3 to 9 eggs in a nest located in a tree or dense vegetation. Both parents take turns incubating the eggs, which hatch after approximately 26 to 28 days.
