Harry Potter’s owl is called Hedwig. In the film, Hedwig is played by a male, which can be seen on the plumage which has black dots.
The snowy owl is a day-active bird.
Some snowy owl species are highly disturbance sensitive during the egg laying and hatching period and can leave the nest with a source of disturbance at a distance of 200–500 m.
During 1978 when there were a lot of rodents, several hundred pairs nested in the mountains of Väster- and Norrbotten and in 1981 five breedings were reported.
