Tree Sparrow Farmland Recovery

The tree sparrow has undergone one of the most dramatic declines of any UK farmland bird but has shown encouraging recovery in some areas through targeted conservation.

Key Facts

Tree sparrow population declined by 95% between 1970 and the mid-2000s
Recovery since 2000 has been real but patchy - population still at 10% of 1970 levels
Distinguished from house sparrow by chestnut cap and black cheek spot
Nest in tree holes and nest boxes in farmland hedgerows and woodland edge
Seed-eating bird heavily reliant on overwinter weed seeds and spring invertebrates

Welfare Considerations

Tree sparrow recovery has been driven by targeted nest box provision and supplementary feeding through agri-environment schemes. Loss of winter stubbles and removal of hedgerow trees were key causes of decline.
