Native to the Old World, the Eurasian Tree Sparrow was released into the St. Louis, Missouri, area in 1870, where it became established. Unlike its close relative, the House Sparrow, it has not spread very far from the original point of introduction.
Calls a slightly metallic "cheep, chirrup." Song a series of cheeps.
