Yellowhammer

The Yellowhammer is one of Europe's most familiar farmland songbirds, a bunting whose breeding males show a brilliant lemon-yellow head that makes them conspicuous perched on hedgerow tops and fence wires across open agricultural country.

Appearance

Breeding males have a bright yellow head and underparts, variably marked with fine dark streaking, a chestnut-streaked back, and a rich chestnut rump. Females and non-breeding males are duller and more heavily streaked, with less extensive yellow, but the warm chestnut rump remains a useful clue in all plumages.

Key Field Marks

• Bright yellow head and underparts in breeding males
• Chestnut, unstreaked rump — visible in flight and a key feature in all ages/sexes
• Streaked chestnut-brown back
• Long, white-edged tail
• Stout, conical bunting bill

Similar Species

Cirl Bunting males have a similar yellow face but show a black throat and olive breast band, quite different from the Yellowhammer's cleaner yellow underparts. Female and winter buntings can be confusingly similar to one another, but the Yellowhammer's warm chestnut, unstreaked rump is the most reliable mark separating it from Reed Bunting and Corn Bunting, both of which have streakier or greyer rumps.

Habitat

Yellowhammers are classic birds of open, mixed farmland — hedgerows, field margins, heathland edges, and scrubby commons with scattered bushes for song perches and nesting cover. They avoid dense woodland and closed urban habitats.

Range and Migration

The species breeds across most of Europe and into western Asia and has been introduced to New Zealand. Most populations are resident or make only short-distance movements, though northern and eastern birds may move south in harsh winters, sometimes joining mixed finch and bunting flocks on stubble fields.

Behavior

Outside the breeding season Yellowhammers often forage in flocks on farmland, particularly stubble fields and areas of spilled grain, sometimes mixing with other buntings, finches, and sparrows.

Voice

The song is one of the best known in the European countryside: a fast series of similar chirping notes followed by one or two longer, drawn-out notes, popularly rendered as "a little bit of bread and no cheese." The call is a sharp, metallic "tzit."

Nesting and Breeding

The nest is built low in a hedge bank, tussock of grass, or low shrub, a cup of grass and moss lined with fine roots and hair. Clutches of 3-5 eggs, distinctively marked with fine dark scrawls (giving rise to the old country name "scribble lark"), are incubated by the female for about 12-14 days.
