174 Bangs, JVezv Birds from Easterii North America. \_h^^\ 



forms in Florida and Georgia. Thus Bluebirds taken in northern 

 Florida in winter are often individuals of the northern form, 

 as are most of the Great-crested Flycatchers, and Kingbirds 

 found there in early spring. With birds that are non-migratory, 

 or whose wanderings extend over a limited area, one need be less 

 careful in this particular ; but even then it is better to compare 

 only breeders. A rather interesting case in point was one I 

 noticed at St. Mary's, Georgia, where, on the great salt marsh in 

 early April, there were two lots of Seaside Finches. One was the 

 dark colored breeding bird of the region, conspicuous in the 

 drier short grassed parts of the marsh and the patches of rush, 

 in full song and worn breeding plumage. The other consisted 

 of northern birds, in winter plumage, songless, and skulking 

 about the long grass at the edges of the creeks. The two lots 

 kept as much removed as if they bore each other no relationship. 



There are more races of eastern birds worthy of separation 

 than are included in the present batch, but those I deal with here 

 are such as have been particularly brought to my notice in work 

 that I have done in the field during the last few years. 



I have had ample material to work with and have been able to 

 examine skins from nearly every place I have wished to see them 

 from. Besides the comparatively small but carefully chosen col- 

 lections Mr. W. W. Brown, Jr., and I have made in Georgia and 

 Florida, in the last few years, I have had access to the private 

 collection of William Brewster, Esq., and that of the Museum of 

 Comparative Zoology, both containing enormous series of eastern 

 birds from very many important localities. Gerrit S. Miller, Jr., 

 Esq., has also sent me specimens from his collection that I par- 

 ticularly desired to see. 



All measurements are in millimeters and were taken with 

 dividers.
