The yellowhammer (Emberiza citrinella) is a strikingly coloured bunting of farmland and scrub edges, once one of the most common birds of the British agricultural landscape. Population declines of over 60% since the 1980s have placed it on the Red List of Birds of Conservation Concern, making it an emblematic species of farmland bird decline.
Ecology & Breeding
Yellowhammers favour a mosaic of arable fields, hedgerows, and scrubby margins. They nest in dense hedgerow bases and field margins, raising 2-3 broods between April and August. Diet is primarily seeds (year-round) supplemented by invertebrates during the breeding season when growing chicks require protein-rich food. The male's song — a rasping "a little bit of bread and no cheese" — is a classic sound of the agricultural countryside.
Causes of Decline
Loss of winter seed: The shift from spring-sown cereals to autumn-sown cereals eliminated the over-wintered stubble that provided critical seed food through winter, when yellowhammers face the greatest starvation risk
Hedgerow loss and management: Mechanical flailing reduces the dense, bushy structure needed for nesting
Reduced invertebrate availability: Pesticide use has reduced caterpillar and insect food for chicks
Loss of mixed farming: Specialisation eliminates the crop diversity that supported year-round seed availability
Conservation Approaches
Overwinter stubbles: Retaining cereal stubbles through winter under agri-environment options provides critical seed food; evidence shows significant benefits for yellowhammer winter survival
Wild bird seed mixes: Sown in field corners or margins; provide year-round seed throughout winter
Hedgerow management: Rotational cutting leaving some hedgerow uncut each year maintains the dense bushy structure needed for nesting
Field margins: Uncultivated, herb-rich margins provide nesting habitat and invertebrate food
