Overview
Eurasian tree sparrow

Eurasian tree sparrow

Wikipedia

The Eurasian tree sparrow is a passerine bird in the sparrow family with a rich chestnut crown and nape and a black patch on each pure white cheek. The sexes are similarly plumaged, and young birds are a duller version of the adult. This sparrow breeds over most of temperate Eurasia and Southeast Asia, where it is known as the tree sparrow, and it has been introduced elsewhere including the United States, where it is known as the Eurasian tree sparrow or German sparrow to differentiate it from the native American tree sparrow. Although several subspecies are recognised, the appearance of this bird varies little across its extensive range.

Typical Environment

Breeds widely from western Europe across Siberia to East Asia, and south into parts of Southeast Asia. It occupies farmland, hedgerows, open woodland edges, rural settlements, parks, and gardens. Avoids dense forests and treeless high mountains, but adapts well to mixed agricultural mosaics. Introduced populations occur in a few regions, including the central United States.

Useful to know

Easily told from the House Sparrow by its rich chestnut cap and the distinctive black spot on a clean white cheek. It nests in cavities, walls, and nest boxes, often in loose colonies near farmland and villages. Although globally common, it has declined locally in parts of Europe due to agricultural intensification and habitat changes.

Behaviour

Temperament

social and active

Flight Pattern

short rapid wingbeats

Social Behavior

Gregarious outside the breeding season, forming flocks that forage in fields and around settlements. Typically nests in cavities in trees, buildings, or nest boxes; may nest semi-colonially. Pairs are generally monogamous, and both sexes help feed the young.

Migratory Pattern

Partial migrant

Song Description

A series of sharp, dry chips and chirps, often delivered in rapid bursts from a perch. Less varied than the House Sparrow, with harsh, metallic notes and constant contact calls within flocks.
