The North American Breeding Bird Survey estimated that numbers increased over 5% per year between 1966 and 2015. Partners in Flight estimates a global breeding population of 20 million, and it is unclear what percentage occurs in the U.S., but it is probably very small. The species rate a 5 out of 20 on the Continental Concern Score. Eurasian Tree Sparrow is not on the 2016 State of North America's Birds' Watch List.Back to top
