are known to frequent such localities. The following remark per- 

 haps refers to both forms : "The Prairie Warbler is by far the most 

 abundant of all the genus on the Bahamas, even as far south as 

 Inaugua, throughout the winter, remaining as late as the last week in 

 April. They are found everywhere, in pine ^voods, scrublands, fields, 

 and even among the mangroves of the little outlying keys. I found 

 them also abundant about Kingston, Jamaica, and a few on Cayman 

 Brae from March 23d to the 28, 1888, but these were evidently migrat- 

 ing and do not remain long." Dr. Wetmore (1916) says: 



In Porto Rico these birds occur at the highest altitudes (above Aibonito, at 

 2,000 feet), and are found in brushy growths, in pastures where there are thick- 

 ets, and along the hedges of emajagua (Paritivm tiliaccum). Dry, brushy 

 growths back of the beaches also are favorite places, and many live in the dry 

 forests of Vieques. In spring there was a marked diurnal movement toward the 

 west, and on Vieques there were distinct waves of migration on March 19 and 

 March 27. Another was noted on Culebra Island on April 9. In each case the 

 birds were in company with many other warblers. * * * T^g pi-airie warbler 

 is apparently much more common as a migrant than as a true winter visitant. 



DISTEIBUTION 



Range. — Eastern United States and the West Indies. 



Breeding range. — The prairie warbler breeds north to northeastern 

 Kansas (Lake Quivira) ; central Missouri (Columbia) ; southeastern 

 Iowa (Lee County) ; northeastern Illinois (Peoria and Chicago) ; 

 central Michigan (Berrien County and Lovells) ; southern Ontario 

 (Honey Harbor, Wasaga Beach, and St. Williams) ; central New 

 York (Schenectady) ; southern New Hampshire (Concord and Man- 

 chester) ; and northern Massachusetts (Haverhill). East to the 

 Atlantic coast from northeastern Massachusetts (Haverhill) to 

 southern Florida (Miami and Key West). South to southern and 

 western Florida (Key West, Fort Myers, and Cedar Keys) ; central

 currences of the prairie warbler in summer have been recorded north 

 to central Iowa (Polk County and West Liberty) ; southeastern Wis- 

 consin (Madison and Appleton) ; northern Michigan (Hillman) ; 

 central Ontario (Frank's Bay and Lake Nipissing) ; north-central 

 New York (Holland Patent) ; and southern Maine (Sanford and 

 Little Green Island) . The first known occurrence in Ontario was in 

 1900, and it now breeds to the shore of Georgian Bay. 



Winter range. — The prairie w^arbler is found in winter north to 

 southern South Carolina rarely (Beaufort and Charleston, occasion-
