Bird of the week - Common Swift
Common Swift -Apus apus-
The Common Swift is the only representative of the Swift family breeding in Norway. It's a fantastic flyer spending more or less all its life in the air, even when it's sleeping.
This species spends the winter in the sub-Saharan Africa, and it is among the last migratory birds coming to Norway in the spring. Most of them appear in mid-May, while the return is already in August.
It is common to see the Common Swift in populated areas, where it usually builds the nest under roof tiles of houses and garages.
