Arrives on the breeding areas mainly in April (late March in the south, May or even June in the far northeast), returning south in August-September, passage continuing until October, wintering in sub-Saharan Africa. Abundant on passage over most of Europe, the Middle East and North Africa. Birds from the far east of Siberia migrate over 15,000 km to winter in South Africa; in proportion to its size (125 million body lengths!), the longest migration of any bird.
There are 3 subspecies:
Open deciduous woodland, bushy areas, parks and gardens. Also in mixed forest and young conifer plantations, hedgerows and shelterbelts. On passage occurs in all types of habitat with trees and bushes.
