Short-eared Owl

Scientific name: Asio flammeus

Occurring over nearly all of North America in at least part of the year, the Short-eared Owl is resident in some areas but migratory over much of its range. It is easiest to see at dawn and dusk, though Short-eared Owls can be active at any time of the day or night. The size of Short-eared Owl breeding territories varies considerably, and appears to be related to prey abundance.

Short-eared Owls that nest farther north usually have larger clutches of eggs than more southerly nesting birds. Collisions with cars and barbed wire fences kill some Short-eared Owls each year, but there is not enough information to fully understand their typical lifespan or mortality causes.
