Asio otus

Resident and migartory; migration poorly understood. Nomadic in response to fluctuating prey numbers in N Europe: overwinters N to C Finland during years with abundant prey, otherwise migratory in most of Fenno- Scandia and ycross northernmost parts of Asian range; birds breeding in Europe may winter as far S as Egypt, but largely sedentary in S Europe; Azores and Canary Is populations non-migratory. Accidental Iceland, Spitsbergen, Bear I, Iraq, Kuwait; in China, breeds in N, winters in S; Asian breeders winter as far S as N India and Indochina. Spring and autumn movements in appropiate directions in USA suggest regular migration (1 ringed in Montana recovered in Guanajuato, Mexico, having travelled 3200 km); presumably regular migrant in N Canada; commonly winters in breeding range throughout USA and extreme S Canada; accidental Alaska, Bermuda and Cuba.
