Bird of the week - Willow Warbler

Willow Warbler -Phylloscopus trochilus-

This species is Norway's most common bird that breeds all over the country.

The Willow Warbler is a migrating bird that overwinters in Africa. It also breeds at Lista, but it is especially remarkable here by the large number of individuals that migrate through this area. The migration here usually starts in late April and continues into May. The first ones to arrive are the males, followed by the females later.

The Willow Warbler has a gentle song and nests on the ground. If you are not observant, it's easy to miss it, despite being very common. At Lista Bird Observatory, the Willow Warbler is one of the most ringed species. The numbers from the station show a tendency of earlier arrival in the spring.

The use of playback in the autumn during the first years from 1990 to 1993 is the reason why these years have been taken out of the material. Therefore, the standardized monitoring for this species is valid from 1994.

Data from Lista Fuglestasjon since 1990:
