The Phoebe Flycatcher, or Phoebe as it is usually called, is an 

 abundant summer resident in Illinois and Wisconsin, breeding 

 throughout both states. In connection with its size, the dark brown 

 or blackish lower mandible and the white outer vane of the outer tail 

 feather will easily distinguish it from other local species. 



It arrives from the south early in April and at once begins mating. 

 The nest is rather large, composed of moss, grass and mud, and lined 

 with hair and feathers. It is built on rocks, beams of old buildings, 

 bridges, etc. The eggs are 5 or 6, usually pure white, but sometimes 

 showing a few dots or spots of brown. Size about .82 x .56 inches. 



The Field Museum collection contains the following sets of eggs 

 from northern Illinois, i egg, Joliet, 111., May 8, 1906; 5 eggs, 

 Chicago, 111., May n, 1904; 5 eggs, Joliet, 111., June 17, 1905; 5
