The yellowhammer is a farmland bunting that has declined severely due to changes in agricultural practice that reduce winter food supply and nesting habitat.
Yellowhammer welfare is primarily affected by food availability and habitat quality. Loss of overwinter stubbles following switch to autumn-sown cereals reduced seed availability, causing starvation-driven population decline. Hedgerow removal reduces nesting sites and increases predation exposure. Late-season agricultural operations disturb active nests. Agri-environment scheme uptake that retains mixed farming elements, including spring cropping and overwinter stubbles, directly improves yellowhammer welfare and population trends.
