Eurasian Tree Sparrow

Description:

The Eurasian Tree Sparrow is 12.5–14 cm (5–5½ in) long, with a wingspan of about 21 cm (8.25 in) and a weight of 24 g (0.86 oz), making it roughly 10% smaller than the House Sparrow. The adult's crown and nape are rich chestnut, and there is a kidney-shaped black ear patch on each pure white cheek; the chin, throat, and the area between the bill and throat are black. The upperparts are light brown, streaked with black, and the brown wings have two distinct narrow white bars. The legs are pale brown, and the bill is lead-blue in summer, becoming almost black in winter.

Habitat:

The Eurasian Tree Sparrow's natural breeding range comprises most of temperate Europe and Asia south of about latitude 68°N (north of this the summers are too cold, with July average temperatures below 12°C) and through Southeast Asia to Java and Bali.

Notes:

I spotted this in Beihai Park in Beijing.
