This is a Hawk Owl landing in a tree top in Sweden that I took in May this year. They occur at low density in the boreal forest zone right across Europe, Siberia and North America. I think that they are the only owl that is most active during the daytime. Other daytime owls are crepuscular, being most active at dusk and dawn. They eat small mammals and birds and I saw this one bring in a small vole which was probably Grey-sided Vole (Myodes rufocanus).
