The long-eared owl is called Long-eared Owl in foreign language, and there are 4 subspecies.
The long-eared owl mainly feeds on rodents such as mice, and also eats small birds, mammals and insects. Such as finches, warblers, bats, beetles, beetles, locusts, mole crickets, etc.
The call of the long-eared owl: The male bird makes a vague ooh call, about once every two seconds. The female bird responds with a relaxed nasal sound paah. The warning call is kwek, kwek. When begging for food, the young birds make a long and sad peee-e sound. During the breeding season, they often call at night, and their sound is low and long, like a repeated "hu-hu-".
The breeding season of the long-eared owl is from April to June, and they like to call especially at this time. Because they mostly show off their courtship at night, the way they do it is relatively simple, and they can only do some close-range performances, such as bowing, flapping wings, kissing each other, preening feathers, etc. Sometimes they also flutter their wings, make a strange crackling sound in their mouths, and take turns to switch their feet. They nest in the forest, usually using the old nests of crows, magpies or other birds of prey, and sometimes nest in tree holes. Each nest lays 3-8 eggs, usually 4-6 eggs. The eggs are white, oval, 39-45 mm × 32-35 mm in size, 43 mm × 33 mm on average, and weigh 19.6 grams.
The incubation process is entirely undertaken by the female bird, and the incubation period is 27-29 days. Its chicks are late-maturing and leave the nest 45-50 days after hatching.
The migration behavior of migratory birds is more affected by food factors than other migratory birds with stable phenology. For example, a group of long-eared owls overwintering have been recorded in Shenyang in the northeast, while the time and location of long-eared owls in other wintering areas are not very stable. In addition, food also affects the reproductive success rate of long-eared owls and their population size.
