Asio flammeus
Short-eared Owl
The Short-eared Owl is a medium-sized owl with a rounded head and small ear tufts. Its plumage is mottled brown and buff, with streaking on the breast. The wings are broad and rounded, with distinctive black wrist marks visible in flight.
Both sexes are similar in appearance, with females slightly larger. The bill is short and thin, black in colour and hooked. Its feet are black with a yellow sole.
Juveniles resemble adults but may have a darker facial disk and more uniform wing colouration.

Short-eared Owls inhabit open landscapes worldwide, including grasslands, marshes, tundra, and agricultural areas. They are found across North and South America, Europe, Asia, and parts of Africa.
In the UK, they breed in Scotland and northern England, with winter visitors across the country. In North America, they breed in Canada and northern U.S. states, wintering further south.

Short-eared Owls primarily feed on small mammals, especially voles and mice. They hunt by flying low over open areas, using their keen hearing to locate prey.
During prey shortages, they may also consume small birds, insects, and amphibians.
Short-eared Owls are known for their low, wavering flight over open areas while hunting. They are more diurnal than most owls, often active during daylight hours, especially at dawn and dusk.
These owls are generally solitary but may form loose communal roosts in winter.
Short-eared Owls are generally quiet outside the breeding season. During courtship and territorial disputes, males produce a series of rapid, hollow hoots, described as 'voo-hoo-hoo'.
When alarmed, they may emit a barking 'keee-ow' call. Females and young make raspy hissing sounds when begging for food.
Short-eared Owls typically breed between March and June, depending on location. Males perform aerial displays to attract mates, including wing-clapping and calling.
Nests are simple scrapes on the ground, often concealed by tall grass or low shrubs. Females lay 4-7 creamy-white eggs, which are incubated for about 24-29 days.
Both parents care for the young, which fledge at around 14-17 days old, but remain dependent on adults for several weeks.
The Short-eared Owl typically lives for 7 to 15 years, with a maximum recorded lifespan of 21.8 years.
Like all birds, lifespan can be affected by factors including predation, habitat quality, disease, and access to food sources.
While listed as Least Concern globally, Short-eared Owl populations are declining in many areas due to habitat loss and degradation.
Conservation efforts focus on preserving grasslands and managing agricultural practices to maintain suitable hunting and nesting grounds.
Marsh Owl, Grass Owl
Main predators include larger raptors such as Great Horned Owls, eagles, and Northern Goshawks. Ground predators like foxes and coyotes may also prey on nests and fledglings.
