Corn Bunting

The Corn Bunting is the largest and plainest of the European buntings, a bird of open arable land recognized as much by its jangling song as by its appearance.

Unlike the Yellowhammer or Reed Bunting, its plumage shows no bright colors or bold head patterns; both sexes are streaked brown and buff throughout.

It has declined significantly in parts of its range due to agricultural intensification, making its feathers a less common but still identifiable find in the right open farmland habitat.

Size & Shape

• Feathers are notably larger and the bird stockier than other buntings; the bill is heavy and conical, reflected in more robust facial feathering.
• Tail is short and only shallowly notched.

Color & Pattern

• Upperpart and underpart feathers: streaked brown and buff throughout, with dark streaking on the breast and flanks forming a loose necklace effect.
• No yellow, chestnut rump, or black head markings are present, unlike Yellowhammer or Reed Bunting.
• Sexes are alike, unusual among European buntings.

Similar Species

• Larger overall size and lack of any bright color or bold facial pattern separates Corn Bunting from Yellowhammer and Reed Bunting; can resemble a large lark or sparrow but has a distinctly heavier bunting bill shape reflected in feather-covered facial structure.

Overall Plumage

Streaked brown and buff throughout, with a loose dark necklace of streaking across the upper breast.

Sex & Age Differences

Sexes look alike, unlike most other buntings. Juveniles are similar but with slightly softer, buffier streaking.

Molt

One complete molt after breeding in late summer.

Habitat

Open arable farmland, unimproved grassland, and areas with scattered fence posts or wires for singing perches.

Range

Breeds across Europe, North Africa, and western Asia, though with significant regional declines.

Movements

Mostly resident, forming loose flocks on stubble and farmland in winter.

Behavior

Often perches conspicuously on wires or fence posts to deliver its jangling song, likened to keys being shaken.

Diet

Feeds on seeds and grain for much of the year, taking invertebrates during the breeding season.

Nesting

Builds a grass nest on or near the ground in open farmland vegetation.

Voice

A distinctive jangling, jingling song often compared to the sound of rattling keys.

Field Notes

A plain, heavily streaked brown feather from a bird larger than a sparrow, found on open arable farmland with scattered perches, points toward Corn Bunting.
