Tree Sparrow Welfare on UK Farmland

Tree sparrows have declined by 93% in the UK since the 1970s and are now largely confined to areas with targeted agri-environment management providing overwinter seed and nest boxes.

Key Facts

Tree sparrows declined 93% between 1970 and 2008 in the UK
They differ from house sparrows in having a brown crown and black cheek spot
They are colonial nesters and respond dramatically to provision of nest boxes and supplementary seed
Recovery is most successful where nest box schemes are combined with wild bird seed plots

Welfare Considerations

Tree sparrow welfare in the UK is almost entirely dependent on targeted conservation management. Populations that lack access to supplementary seed in winter suffer high mortality during cold periods. The species is now so locally distributed that welfare interventions at individual farms and estates have measurable population-level impacts.

What You Can Do

Install tree sparrow nest boxes in suitable farmland habitats in clusters of three or more
Provide supplementary seed through the winter months at established tree sparrow sites
Support agri-environment scheme options that include wild bird seed mixes
Monitor nest box occupancy and report results to local Wildlife Trusts and the RSPB
