The Eurasian Tree Sparrow (Scientific Name - Passer montanus) is a small sparrow that closely resembles the larger House Sparrow. They have mostly light brown upper parts and light breast with no streaking. The wings are mostly brown with some black spots and distinct white bars. They have a thick dark bill and distinct black ear patches and a black patch on the chin and throat. They range from Europe to South East Asia but are rare in the Middle East and Indian sub continent. They were introduced to the USA in the Missouri area and have not spread far from that area in North America. The American Tree Sparrow looks similar however has a rust coloured line extending back from the eye and no black ear patch or throat. Photos taken in Da-an Forest Park, Taipei, Taiwan in August 2015.
