The Long-eared owl
The long-eared owl's (Asio otus or Strix otus) breeding season is from February to July. This bird is partially migratory, moving south in winter from the northern parts of its temperate range. Its habitat is forest close to open country. Overall, these owls are secretive, and are rarely seen.
It nests in trees, often coniferous, using the old stick nests of other birds such as crows, ravens and magpies and various hawks. The average clutch size is 4–6 eggs, and the incubation time averages from 25–30 days. It will readily use artificial nesting baskets. An unusual characteristic of this species is its communal roosting in thickets during the winter months. The young have a characteristic call, likened to a rusty hinge.
The long-eared owl hunts over open country by night. It is very long winged, like the similar short-eared owl, and glides slowly on stiff wings when hunting. Its food is mainly rodents, small mammals, and birds. In Europe it faces competition from the tawny owl and is most numerous in localities where the tawny is absent, notably in Ireland, where the long-eared is the dominant owl; it can occasionally be seen even in Dublin city centre.
Males occupy nesting territories first and may begin their territorial calling in winter. Nesting occurs mainly from mid March through May. During courtship, males perform display flights around nests. Display flights involve erratic gliding and flapping through the trees with occasional single wing claps. Females respond by giving their nest call. The female selects a nest by hopping around it, while the male displays above. She then performs display flights as well, and flies repeatedly to the nest. Leading up to mating, the male approaches the female after calling and performing display flights, then waves his wings as he sidles up to her. Mutual preening and courtship feeding also occur. After pairing, adults roost close together, but the female tends to roost on the nest after it has been selected.
Long-eared Owls hunt mainly by ranging over open rangeland, clearings, and fallow fields. They rarely hunt in woodlands where they roost and nest. They hunt mainly from late dusk to just before dawn, flying low to the ground (1-2 m), with the head canted to one side listening for prey. When prey is spotted, the Owl pounces immediately, pinning the prey to the ground with its powerful talons. Smaller prey is usually swallowed immediately, or carried away in the bill. Larger prey is carried in the talons.
Long-eared Owls feed primarily on mammals. In most areas voles are the most common prey, but deer mice are the most important prey in other areas. In southwestern deserts, pocket mice and kangaroo rats are primary foods. Other mammal prey includes squirrels, bats, chipmunks, gophers, shrews, moles, and cottontail rabbits. Birds are also taken, occasionally on the wing. Most bird prey are smaller species that occur on or near the ground. Bird prey includes meadowlarks, blackbirds, juncos, Horned Larks, doves, bluebirds, and thrashers. Larger birds such as grouse and screech-Owls are occasionally taken. Long-eared Owls sometimes eat insects, frogs, and snakes.
Pellets are fairly large, about 5.1x1.9 cm. They are oval or cylindrical, greyish, and compact with many bones, skulls, and teeth. They are regurgitated 3 to 4 hours after eating.
