Great Grey Owl - Strix nebulosa


Because of its geographic range (Arctic Circle region), this is a nocturnal raptor which may, and sometimes has to, hunt during the day (6-month day/night alternation). It is the same for the Northern Hawk Owl and the Snowy Owl. It is particularly well-adapted to the Taiga. When it flies in a dense forest, it is able to fold one wing in when flying towards a tree trunk and then fold it back out again once the obstacle has been passed. Like many nocturnal raptors, it is rather a solitary bird. Pairs only stay together for the breeding season. It is sedentary in principle, in spite of the climate, but sometimes it migrates a short distance to the south to find food.
