 Atlantic coast, breeding, as a rule, north of North Carolina. It ranges in 

 winter south to Central America and the West Indies, l^eing connnon in 

 Florida in some localities.

Length. 12.50; Wing, 4.50; Bill, 2 ; Tarsus. 2.10. 



This species ranges from temperate North America 

 southward to the West Indies and Northern South 

 America. 



It breeds along the Atlandc coast nearly throughout 

 its range. It is common in Florida where it breeds, being veiy abundant in 

 some localities. 



The nest is placed in a bunch of reeds or rushes, sometimes on small 

 bushes. 



The eggs are from four to six, pale bluish white. I have found as many 

 as a dozen nests of this species within a distance of tifty yards on some of 

 the small Florida ponds, but it seems to be local, as many ponds in the same 

 locality, seemingly equally suitable, did not contain a single individual.
