Fieldfare

Turdus pilaris

The fieldfare is a member of the thrush family Turdidae. It breeds in woodland and scrub in northern Europe and across the Palearctic. It is strongly migratory, with many northern birds moving south during the winter. It is a very rare breeder in the British Isles, but winters in large numbers in the United Kingdom, Southern Europe, North Africa and the Middle East. It is omnivorous, eating a wide range of molluscs, insects and earthworms in the summer, and berries, grain and seeds in the winter. Source

Movement and weather

Each season it is first heard regularly where daytime highs are around 15°C (typically 7 to 19°C, from 22 areas). That range is wide, so temperature alone does not explain when it turns up.

Over the weeks it was present in the past year, its centre in Europe ranged from 56°N in November to 66°N in May, about 1,100 km apart.

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.
