winter ■ home. Special attention needs to be called to this fact, 

 because nearly a dozen species of this family — among which may be 

 noted particularly the greater and lesser yellow-legs and the white- 

 rumped sandpiper — ^have been reported as breeding near the southern 

 end of South America. In no case has it been claimed that the eggs 

 have been found, and all the records are based on the finding of 

 young not fully grown or in most cases simply from the presence of 

 individuals during the usual breeding season of local species. This 

 latter reason is not even presumptive of breeding. Nearly a hun- 

 dred species of North American birds escape the winter of the North- 

 em Hemisphere by visiting South America, and they remain there 

 through what is the breeding season of the resident species, but do 

 not themselves undertake any household cares. It may be stated 

 positively that none of the Limicolse that breed north of the equator 

 breed also in the southern part of their range.
