Willow Tit

Poecile montanus

The willow tit is a passerine bird in the tit family, Paridae. It is a widespread and common resident breeder throughout temperate and subarctic Europe and across the Palearctic. The plumage is grey-brown and off-white with a black cap and bib. It is more of a conifer specialist than the closely related marsh tit, which explains its breeding much farther north. It is resident, and most birds do not migrate. Source

Movement and weather

Each season it is first heard regularly where daytime highs are around 21°C (typically 11 to 24°C, from 13 areas). That range is wide, so temperature alone does not explain when it turns up.

Arrival dates

The week it was first heard regularly in each region, after at least six weeks away. Dates differ from south to north, so a region has a range.
