LONG-BILLED DOWITCHER 121 



Winter. — Dowitchers occur in winter as far south as Ecuador and 

 Peru. Dr. Frank M. Chapman (1926) referred the birds collected 

 in Ecuador to soolopaceus. Nonbreeding birds, or immatures, re- 

 main there all summer, as they do in other parts of their winter 

 range. I have taken both forms of dowitchers in Florida, where 

 they winter regularly in small numbers.
