Corn Bunting vs Song Sparrow

Corn Bunting

Emberiza calandra

How to recognise a corn bunting?

General appearance

The corn bunting is a robust bird measuring approximately 16-19 cm in length. It possesses a distinctively stout, yellowish bill and a thick neck. The plumage boasts a brownish coloration interspersed with darker streaks and its underparts possess a whitish hue. The torso appears somewhat bulged, with rounded wings and a rather blunt tail. During flight, their short wings flutter quickly.

Male vs female

Male and female corn buntings are virtually indistinguishable by physical appearance alone as both sexes possess similar plumage coloring and size. However, behavioral differences can be used to tell them apart. Males are known for their unique song which sounds like jangling keys, used primarily for mating calls. Males are also territorial during breeding season.

Juvenile

Juvenile corn buntings resemble adults in size, but their plumage has a more ruffled appearance and is slightly paler. They lack the darker streaking seen in adults until they mature. Juvenile birds also lack the bold territorial and vocal behaviors of adult males until they reach sexual maturity.

Size

6.7 - 7.5 in/1.1 - 2.4 oz

Habitat

Primary habitat

Corn buntings primarily inhabit open farmland and rugged grasslands across Eurasia. They prefer cereals crops, margins of fields, and pastureland for nesting.

Additional range

In unexpected environments, corn buntings may be found in shrublands, woodlands or even sandy coasts. They are adaptable to a temperate maritime climate as observed in Scotland and Northern Europe.

What do corn buntings like to eat?

Natural diet

Corn buntings primarily consume seeds and grains from various grasses and cereal crops like wheat and oats. Additionally, they feed on insects, especially during the breeding season, to provide necessary protein. Common insects in their diet include beetles, caterpillars, and grasshoppers.

Bird feeders

While corn buntings do not frequently visit bird feeders, they may occasionally eat common offerings such as millet, cracked corn, and mixed bird seed provided in open tray feeders, which mimic their natural foraging habits.

What does a corn bunting sound like?

The Corn Bunting produces a distinctive jangling song, often likened to jingling keys, comprised of repeated phrases with several notes. Its typical call is a sharp 'tik'. This bird is known for mimicking the sounds of other birds and incorporating them into its song. The song is sung from a high perch or in flight and is particularly prominent during the breeding season. The male's song, used to attract females, can last for several minutes. Their vocalizations are less active during winter.

Song Sparrow

Melospiza melodia

How to recognise a song sparrow?

General appearance

A song sparrow is the size of a robin, with a fairly long tail. Its distinctive markings include a striped face and streaks on its chest, often merging into a central blotch. The bird displays a range of colors, including black, brown, gray, red, and white. Its wings are broad and its tail can be notched, rounded, or square-tipped. It is often seen in open fields.

Male vs female

Both male and female song sparrows have similar appearances, making it difficult to tell them apart by sight alone. Both genders share the same size, coloration, and physical traits, such as their striped faces, long tails, and chest markings.

Juvenile

Juvenile song sparrows have similarly colored plumage to adults but typically appear more muted. Their chest streaks may not be as prominent and can take some time to fully develop. As they mature, they grow into their characteristic markings and colorations.

Size

4.7 - 6.7 in/0.4 - 1.9 oz

Habitat

Primary habitat

The song sparrow typically inhabits thickets, brush, marshes, roadsides, and gardens, particularly in areas with brushy fields, streamsides, shrubby marsh edges, woodland edges, hedgerows and well-vegetated gardens.

Additional range

Its environmental range varies, from coastal populations in salt marshes to sparse habitats such as dense streamside brush in southwestern deserts and any dense low cover on the Aleutian Islands, Alaska.

What do song sparrows like to eat?

Natural diet

The song sparrow's diet consists primarily of insects and seeds. During summer, it consumes a wide variety of insects, including beetles, grasshoppers, caterpillars, ants, and wasps, as well as spiders. In winter, its diet shifts to focus heavily on seeds, particularly those of grasses and weeds. In coastal marshes and island habitats, song sparrows may also feed on small crustaceans and mollusks and occasionally small fish.

Bird feeders

Song sparrows are known to visit bird feeders, where they often consume seeds. Common foods at feeders include millet, cracked corn, and sunflower seeds, which provide a convenient supplement to their natural diet, especially during colder months when insects are less abundant.

What does a song sparrow sound like?

The song sparrow vocalizes with an array of distinct patterns. Its song typically starts with 3 short notes, interpreted as "Madge-Madge-Madge," followed by a varied trill mimicking "put-on-your-tea-kettle-ettle-ettle.” The call patterns mirror a falling, rising, and undulating rhythm. The types of calls emitted include a buzz, chirp or chip, hi, trill, and a whistle, creating a complex communication repertoire unique to this bird species.

How to tell the Corn Bunting from the Song Sparrow

Visual differences

The Corn Bunting is visibly larger, 6.3-7.5 inches long, with a stout yellowish bill and a robust, thick-necked body. Its plumage is primarily brown with dark streaks and whitish underparts. The Song Sparrow, 4.7-6.7 inches long, features a slender body with a longer, notched tail, and a more variably colored plumage, including brown, gray, and red with prominent chest streaks merging into a central blotch. Its face is distinctly striped. The Corn Bunting's bill is thicker and more conical than the sparrow's finer bill.

Key differences and behavior

Corn Buntings and Song Sparrows exhibit notable behavioral and ecological differences. Corn Buntings, weighing 1.1-2.4 ounces and measuring 6.7-7.5 inches, prefer open farmlands across Eurasia, using cereal crops for nesting. They primarily eat seeds and insects, singing a unique jangling melody during breeding to attract mates and establish territories. In contrast, Song Sparrows, at 0.4-1.9 ounces and 4.7-6.7 inches, inhabit thickets, marshes, and gardens across diverse North American environments. They have a varied song with multiple melodies, singing every few seconds. Their diet includes insects, seeds, and occasionally crustaceans. Song Sparrows defend smaller territories, often chasing potential mates with a distinct fluttering flight. While buntings construct ground nests in open fields, Song Sparrows use shrubs or grass clumps. This demonstrates the adaptable nature of Song Sparrows in varied landscapes, while Corn Buntings are more farmland-specific.
