It is spring, many birds have not yet flown away and stayed at wintering grounds. You can observe interesting competitions in getting food. A lot of birds are on migration and flights to places where they will nest. See what species it is. Goldfinch , blackbird , nuthatch , siskin , blue tit , lass , linnet , starling , bullfinch , redpoll .
