The Peruvian Avocet (or Peruvian Stilt, as it should be 

 called) is the only species of the genus having webbed feet

 stilts, which, according to my hypothesis, emigrated from 

 the Polar basin along the Pacific coast of America.

The North- American Stilt is an intermediate form between 

 the Common Stilt and the Chilian Stilt. It may be recog- 

 nized by the distribution of the black on the back of the neck, 

 which not oxAy passes underneath the eye but also extends 

 over the crown and joins the black on the mantle. Young 

 in first plumage resemble adults, except that the black is 

 replaced by brown. 



It breeds iu the southern half of North America, and
