throughout Illinois and southern Wisconsin from May until Septem- 

 ber. In northeastern Illinois it breeds about Fox Lake, Joliet, and 

 other localities. Often confused by the ordinary observer with the 

 Bank Swallow. 



Breeds during the latter part of May, and in June. The nest is 

 usually in a hole in a bank, although at times in stone walls or under 

 bridges. The eggs are from 3 to 6, pure white, and measure about 

 .72 x .51 inches. 



Family BOMBYCILLID^. Waxwings, etc. 



This small family contains but two genera and three species. 

 Two of these, comprising the subfamily Ampelinaz or Waxwings, 

 occur within our limits. They are gregarious during migrations and 

 attract attention by their faint whistle, which appears to be their 

 only note. Their food consists of fruit, berries and insects, and they 

 build their nests in trees.
