A quite common winter resident on Lake Michigan, sometimes 

 staying in our vicinity as late as the twentieth of May. Its name 

 Red-breasted is far from appropriate, for its breast is not at all 

 red in color. 



It breeds in the northern portion of North America, migrating 

 southward in winter through the United States. Mr. Robert 

 Ridgway states that it breeds in northern Illinois.*
