Eurasian Tree Sparrow
Range Map
The
Eurasian Tree Sparrow was introduced from Europe
and established in St. Louis, Missouri, in 1870.
It is now also found in east-central Missouri and
western Illinois. The Eurasian Tree Sparrow
occurs in residential areas, farmlands, fields,
and open woodland around St. Louis. It is far
less agressive than its relative the house
sparrow, but has slowly expanded its range to
western Illinois. |
