Northeastern United States, chiefly east of the Allegheny Moun- 

 tains; north to Massachusetts and New York — probably to Ontario'' — 

 casuall}^ to New Brunswick; west to western New York and Pennsyl- 

 vania; breeds southward to the Potomac Valley and Atlantic coast of 

 Maryland and Virginia; in winter southward to North and South 

 Carolina, occasionally to western Florida (Tarpon Springs, etc.), 

 occasionally wintering in northern portions of its range.

« Twenty-four specimens. 

 '' Eighteen specimens. 



Specimens from different localities (breeding birds or those taken during or near 

 breeding season only) average, respectively, as follows:

Four adult males from coast of New Jersey 



Ten adult males from District of Columbia

The five adult females from New Jersey are in greatly worn plumage, which 

 accounts for the lower measurements of their wing and tail. 



1 am not able to perceive the minutest difference in coloration between Massachu- 

 setts birds and those from the District of Columbia, the only difference, apparently, 

 consisting in the slightly larger average dimensions of the former. 



cJ have not seen specimens from Ontario, nor-from any locality in Ohio or 

 northern Indiana; consequently I am unable to state whether tliis form or T. p. 

 iliacus inhabits the area in question. Most likely, however, it is the present one, the 

 range of T. p. iliacus probably not beginning until the prairie districts of western 

 Indiana and Illinois are reached.
