Eurasian Tree Sparrow

The Eurasian Tree Sparrow closely resembles the more familiar House Sparrow but is generally found in more rural, farmland-associated habitats and shows subtly different plumage markings that separate its feathers from its urban relative.

Both sexes look alike in this species, unlike the House Sparrow where males and females differ markedly — a useful fact when comparing feathers between the two.

A Tree Sparrow feather is best distinguished by its chestnut-brown crown color (rather than grey) and, on cheek feathers, a distinct black spot set against an otherwise clean white cheek — features not found on House Sparrow feathers.

Crown and head feathers

• Crown feathers are chestnut-brown across the whole crown, distinct from the grey crown of a male House Sparrow.
• Cheek feathers are white with a small but distinct black spot, a pattern absent in House Sparrows.

Body feathers

• Back feathers are brown, streaked with black and buff, similar in general tone to House Sparrow but slightly smaller.
• A narrow white half-collar is present on the neck.

Size

• Slightly smaller and more compact than House Sparrow feathers.

Confusion species

House Sparrow males show a grey crown and lack the black cheek spot; House Sparrow females are plainer overall without the chestnut crown. The chestnut crown plus black cheek spot combination is diagnostic for Tree Sparrow.

Both sexes of the Eurasian Tree Sparrow look alike, with a chestnut-brown crown, black cheek spot on an otherwise white face, a small black throat patch, and a brown, black-streaked back with a narrow white collar around the neck.

Juveniles are duller and browner overall, with a less distinct cheek spot, becoming more clearly marked after their first molt.

The species undergoes a complete post-breeding molt in late summer.

Tree Sparrows favor farmland, hedgerows, orchards, and open woodland edges, often nesting in cavities in old trees, hedgerow banks, or buildings in rural villages. They are generally less associated with dense urban centers than House Sparrows.

The species is resident across much of its Eurasian range, though some northern and eastern populations may move short distances in winter.

Tree Sparrows feed mainly on seeds and grain, supplemented by invertebrates especially when feeding young, foraging on the ground and in low vegetation, often in small flocks.

They nest in cavities, sometimes in loose colonies, and give a call similar to but slightly sharper and higher-pitched than the House Sparrow's chirp.

A small, brown-streaked feather with a chestnut crown and hint of a black cheek spot, found in farmland or rural hedgerow habitat, points to Eurasian Tree Sparrow rather than House Sparrow.
