Behavior

• Short-eared owls make colonies in order to live together, unlike other owl species
• They are mostly active and seen during the day, quite contrary to other owls
• They chase their preys before killing them off and carrying them afterward in their talons

Mating and Reproduction

Male owls perform a sky dancing session to allure females through wing clapping and singing. In the northern hemisphere, the breeding season is from March to June. Although mainly monogamous, they might be polygamous at times. After the mating, a female owl lays around 1-11 white eggs sizing 1.5-17 inches in her nest that is 10 inches wide and 2 inches long. The eggs are incubated for 21-37 days.

Life-cycle

Hatchlings fledge after 4 weeks and start hunting after 1-2 weeks on their own. They become sexually mature around 1 year of age.
