Note the Rufous on Its Back

Mike Warner

This Prairie Warbler has spent the summer in nearby West Chicago.  It is unusual to have any warblers (except the Common Yellowthroat and Yellow Warbler) remain here after all the others left by the end of May.  There was some speculation that it was mating nearby but only one has been spotted: never two.  This is a male with a bolder face and some rufous coloring on the back.

Which is Which?

Why Did It Stay?
