Family BOMBYCILLID^. Waxwings, etc. 



This small family contains but two genera and three species. 

 Two of these, comprising the subfamily AmpelincE 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.
