Conservation status: least_concern
The 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 have similar plumage, and young birds are duller versions of the adult. This sparrow breeds across much of temperate Eurasia and Southeast Asia and 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.
How To Identify
The Eurasian Tree Sparrow is a small passerine bird, typically measuring 12-14 cm in length. Males are easily distinguished by their bright black bib and contrasting rusty red cheeks, while females exhibit more subdued brown and grey plumage.
Habitat
It inhabits open woodlands, gardens, parks, and cultivated areas across temperate and subtropical regions of Eurasia, preferring areas with scattered trees and human settlements.
Behaviour
Unlike its close relative the House Sparrow, the Eurasian Tree Sparrow is more sociable and forms larger flocks, often roosting communally in reed beds or dense vegetation.
Did You Know?
Despite being one of the most abundant birds in the world, the Eurasian Tree Sparrow was nearly driven to extinction in China during the 1950s 'Four Pests' campaign, when millions were killed. Remarkably, populations have since recovered.
