- The Eurasian Tree Sparrow typically lives near people, but it has been displaced from urban centers and into more rural areas by its larger and more aggressive relative the House Sparrow.
- Outside of North America, the Eurasian Tree Sparrow shows considerable variation in plumage and size, which has resulted in the naming of up to 33 separate races. The North American birds came originally from Germany and are from the most widespread race.
- The oldest recorded Eurasian Tree Sparrow in North America was at least 4 years old, when it was recaptured and rereleased during a banding operation in Illinois in 1972.

Eurasian Tree Sparrow is an introduced species to North American, and though its population is not large, it range is expanding. 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.
