The willow warbler (Phylloscopus trochilus) is a very common and widespread leaf warbler which breeds throughout northern and temperate Europe and the Palearctic, from Ireland east to the Anadyr River basin in eastern Siberia. It is strongly migratory, with almost all of the population wintering in Sub-Saharan Africa. You can hear this bird often but can see it seldom. October to March: wintering in sub Saharan Africa. Mid March to mid May: migrates and arrives in the breeding range. Late April to August: breeding season, usually only one brood but rarely two. August to October: migrates back to Africa.
