American Tree Sparrow

There are so many kinds of sparrows!  35 or more species live in North America, and 15 are found in most of North America.  Here is another.

The American tree sparrow has a rust-colored eye streak and a dark spot in the center of a plain breast.  The thing I am keying in on is the bi-colored bill, black on top and yellow on the bottom.  This bird winters in the northern two thirds of the U.S. and portions of southern Canada.

Photo was taken at the west terminus of Cherry Road in the Henneberry Woods subdivision of Oswego, Illinois.  There are farm fields, meadows, scattered trees, and a wetland in the area.  The Kendall County Forest Preserve District owns part of the property, although it remains undeveloped.
