Corn Bunting

Emberiza calandra

Often called the 'fat bird of the barley,' the Corn Bunting is a master of the open field. Its modest, streaked appearance hides a fascinating social life and a song that sounds exactly like a jingling set of keys.

Behavior

The Corn Bunting is often affectionately known as the 'fat bird of the barley' due to its portly appearance and preference for agricultural land. Unlike many of its colorful bunting relatives, it relies on camouflage, blending perfectly into dry grasses and stubble fields. During the breeding season, males are famously polygynous, often maintaining several mates within a single territory, which they defend from the tops of fence posts or telegraph wires.

You will often see them flying with their legs dangling slightly, a characteristic trait of the species. While they are somewhat shy around humans, they are highly gregarious in the winter, forming large mixed flocks with other finches and buntings to scour harvested fields for fallen grain. Their presence is a hallmark of a healthy, traditional farmland ecosystem.

Camera Tips

To capture the best footage of a Corn Bunting, focus on ground-level activity. These birds are predominantly ground-feeders, so place your AI-powered camera 12 to 18 inches off the ground near the edge of an open field or a 'messy' corner of a garden that borders farmland. Aim the lens toward a flat, cleared area where you can scatter a mix of barley, wheat, or cracked corn. Because they are cautious, ensuring your camera is well-camouflaged with local vegetation will help prevent them from fluttering away.

Lighting is crucial for this species because their brown, streaked plumage can easily look like a 'blob' in poor light. Position your camera facing North to ensure even lighting throughout the day without the sun blinding the sensor. Since they are most active during the 'golden hours' of early morning, high-sensitivity sensors or cameras with good dynamic range will help capture the intricate streak patterns on their breast.

If you want to capture their unique 'jangling keys' song, place a secondary camera or a standalone microphone near a prominent perch, such as a lone bush, a fence post, or a tall weed stalk like a dried teasel. Males use these high points as stages for their territorial displays. Set your camera to a short video trigger (10-15 seconds) with a fast recovery time, as they often hop down to the ground and back up to their perch repeatedly while foraging.

Similar Species

Species that look similar or are commonly confused with Corn Bunting.

Skylark

The Skylark has a noticeable crest on its head and white outer tail feathers, whereas the Corn Bunting is chunkier with a heavier bill.

Yellowhammer

Male Yellowhammers have bright yellow heads; females are more similar but usually show a reddish-brown rump which the Corn Bunting lacks.

House Sparrow

House Sparrows are smaller, have cleaner grey or white cheeks, and different facial markings compared to the uniform streaking of the Corn Bunting.

Frequently Asked Questions

Corn Buntings are most active during the early morning and late afternoon. During the breeding season, males will sing almost continuously from dawn until dusk from a high perch to defend their territory.

To attract Corn Buntings, provide a ground-feeding station with cereal grains like barley and wheat. They are more likely to visit gardens that are open and adjacent to farmland or large meadows rather than enclosed, wooded yards.

Their diet consists mainly of seeds from grasses and cereal crops. However, during the spring and summer, they switch to an insect-rich diet, hunting for beetles, caterpillars, and spiders to provide protein for their growing chicks.

They are generally uncommon in dense suburban areas. They require wide-open spaces and are most frequently found in agricultural landscapes, though they may visit suburban fringes if there are large fields nearby.

While both are streaked brown birds, the Corn Bunting has a much thicker, heavier bill and lacks the Skylark's crest. Additionally, the Corn Bunting does not have the white outer tail feathers that are very prominent on a Skylark in flight.
