Wild Bird: Rook Farmland Welfare

Rooks are highly social corvids whose welfare is linked to the availability of invertebrate-rich pastoral farmland for foraging.

Key Facts

Rooks nest colonially in rookeries, often returning to the same trees for generations
They feed primarily on soil invertebrates including earthworms, extracted by probing
UK rook populations have declined by 28% since the 1970s linked to agricultural intensification
Pasture loss to arable farming reduces the soft soil invertebrate feeding habitat rooks require
Rooks are highly intelligent with complex social behaviour including cooperative food finding

Welfare Considerations

Rook welfare is fundamentally social - colony living is central to their behaviour and psychology. Loss of invertebrate-rich pasture reduces food availability and causes nutritional stress, particularly during the breeding season when chick food demand peaks. Maintaining permanent pasture with good invertebrate communities near rookeries supports welfare for these socially complex birds.

What You Can Do

Support agri-environment schemes that maintain invertebrate-rich permanent pasture
Submit rook count data to BTO monitoring schemes
Locate and record local rookeries for reporting to breeding bird databases
Reduce pesticide use near rookeries that depletes soil invertebrate food supply
Learn about rook intelligence and social behaviour as part of corvid conservation
