Short-eared owls mainly feed on rodents, but also eat small birds, lizards and insects, and occasionally eat plant fruits and seeds.

Short-eared owls are active and hunt at dusk and at night, but they are also active during the day. They usually live on the ground or hide in the grass, and rarely live on trees. They fly slowly and not high, but close to the ground. They often fly with a flapping wing followed by a gliding glider, and the two often alternate. During the breeding period, they often fly while chirping, and the sound is like "no-no-no-", which is repeated many times.

Short-eared owls are winter migratory birds and resident birds in eastern Inner Mongolia, Heilongjiang and Liaoning, and winter migratory birds in other provinces and regions.

The breeding season of short-eared owls is from April to June. Usually nests in grass near swamps, and also nests in rotten wood holes in secondary broad-leaved forests. The nest is usually made of dead grass. Each nest lays 3-8 eggs, occasionally up to 10, or even 14, but usually 4-6. The eggs are white, oval, and 38-42 mm × 31-33 mm in size. The female bird incubates the eggs, and the incubation period is 24-28 days. The chicks are late-maturing, and can fly after being fed by the parents for 24-27 days after hatching.
