Except for a few areas such as Xining in Qinghai, Kashgar and Tianshan in Xinjiang, The Long-eared Owl in China is a migratory bird in most other areas, including summer migratory birds in Heilongjiang, Jilin, Liaoning, eastern Inner Mongolia, northeast Hebei and other places, and from Hebei and Beijing to the south, until Tibet, Guangdong, and the southeast coastal provinces are winter migratory birds.
The breeding season is from April to June, when the song is particularly liked. Because most of them show off at night, the way is relatively simple, so you can only do some close-up performances, such as bowing, flapping your wings, kissing each other, sorting out feathers, etc., and sometimes drumming your wings, making a strange crackling sound in your mouth, and changing your feet in turn. Nests are found in forests, usually using old nests of crows, magpies or other birds of prey, and sometimes in tree holes. 3-8 eggs are laid per clutch, usually 4-6. The eggs are white, the eggs are ovate, the size is 39-45 mm× 32-35 mm, the average is 43 mm× 33 mm, and the weight is 19.6 g. The incubation process is entirely undertaken by the female and the incubation period is 27-28 days. Its chicks are late-blooming and leave the nest after 45-50 days of hatching.
