However, like the northern irruptive owls, long-eared owls tend to appear in unprecedented numbers to the south when a peak prey year is followed by a winter during which prey population crashes. In North America, the migratory habits of long-eared owls are strongly mirrored by those of northern saw-whet : Aves.

In any owl habitat the lack of food due to humans disrupting the environment can lead to death. Most species of owls also won’t reproduce at high rates when their basic needs aren’t met. As a result, there are plenty of types of conservation efforts in place for the natural habitat of owls. Long-eared Owls usually nest in abandoned stick nests, often the nests of magpies, crows, ravens, or hawks. On occasion they nest in cavities or brushy tangles. They do not add nesting material. Females lay 2'10 eggs, usually , and incubate them days. During incubation, the male brings food to the female on the nest.

Of the ring recoveries of Long-eared Owl received by the BTO, around a quarter have been from birds that have been hit by cars. More than is commonly thought, Long-eared Owls, like Barn Owls, may hunt along road verges in the search for food.
Other recoveries show Long-eared Owls that have travelled great distances to migrate. Long-Eared Owl Habits.
During the day: Long-eared owls hide away, roosting amongst thickly-branched trees. In the autumn and winter, groups of up to 20 owls may roost together. Sometimes a roosting bird, or an anxious one, sits close to the trunk of a tree and pulls itself into an upright, slender shape; this helps it to blend in with its surroundings.
LONG-EARED OWL NESTING: Nest Site: does not build nests; reuses abandoned nests, or nests in tree cavities, cliffs, or even on the ground Eggs: usuallymore if food sources are abundant Incubation: days LONG-EARED OWL HUNTING HABITS. Long-eared Owls hunt on the wing, coursing back and forth low above open ground.
They may also hover over prey, or hunt from perches in strong winds. They kill small mammals with a bite to the back of the skull, and often swallow their prey whole. Nesting Long-eared Owls sometimes form loose colonies, occupying nests as close as 50 feet apart. W. Armstrong Nesting and food habits of the Long-eared Owl in Michigan.
Mich. Univ. Publ. Mus. Biol. Ser. 1: 61– Google ScholarCited by: Feeding Habits What Owls Eat. The type of food owls eat depends on the species of the owl. These birds feed entirely on living animals with the size of the prey proportional to the size of the bird, from insects to mammals as large as hares.
A Barn Owl for instance may eat mice, rats and voles. a greater abundance of small mammals were not utilized. The Long-eared Owls, therefore, apparently prefer open, grassy areas to timbered areas. LITERATURE CITED ARMSTRONG, W.
Nesting and food habits of the Long-eared Owl in Michigan. Publ. Mus. Mich. State Univ., GEIS, A. Winter food habits of a pair of Long-eared Owls. This medium-sized owl is widespread but not particularly well known in North America.
It seems to call less often or less conspicuously than many of our other owls, so it may be overlooked in some areas where it nests. In winter, sometimes groups of a dozen or more may be found roosting together in groves of conifers, willows, mesquites, or other trees.
Most studies have focused on food habits and nesting biology. The Long-eared Owl typically nests in trees, laying its eggs in abandoned stick nests of other species. Less often it nests in cavities in trees or cliffs, or on the ground. Although it prefers to nest and roost in dense vegetation, it hunts almost exclusively in open habitats.
Owls roosting with /• Long-eared Owl represents only the second pubhshed record of an interspecific owl roost (both species using the same tree).

The Snowy Owl, which favours the Arctic tundra, will use a hollow in the ground which the female may attempt to scrape out and line with plant material.
Short-eared Owls often nest in or beside tussocks of grass; similar sites are sometimes chosen on rare occasions by Long-eared Owls and Tawny Owls, both usually tree-nesting species.
The long-eared owl (Asio otus) is one of the species belonging to the typical owls (Strigidae) family. There are essentially four recognized sub-species of the long-eared owl. These include, Asio otus otus, which is found in Northern Eurasia, Mediterranean islands, the Middle East, North-Western Africa, northern Pakistan, the Azores archipelago, and east-central China.

: Davorin Tome.Nesting habits and nomadism make this species particularly vulnerable to habitat loss during any season. Due to these factors, short-eared owls are endangered in Michigan, Illinois, and Pennsylvania.
They are also threatened in Minnesota and of special concern in Indiana and Ohio. They are among the rarest nesting owls in Michigan.In the desert Southwest the long-eared owl inhabits a wide elevational range, from sea level to 9, feet.
The owls occur in juniper woodlands and coniferous or deciduous forests at higher elevations. The owls may also nest in riparian woodlands, parks, shelterbreaks along agricultural fields, or orchards.
