somewhat grayer above. Unfortunately midsummer birds are no1 

 available, but would probably show some slight fading. Females 



likewise show no variation according to season. 



Geographic variation, — This form seems remarkably constant 

 throughout its range. I can discover no differences between birds 

 from the Florida Keys on the one hand and those from the Suwanee 

 River and Georgia and South Carolina on the other, when specimens 

 of the same age and sex are compared. It would naturally be 

 expected that Louisiana birds would show variation in the direction 

 of C. p. pallescens, but all efforts to secure authentic specimens from 

 that State having failed, this question must be left in abeyance. 



Individual variation. — This is evident in several respects. The 

 amount of metallic spotting on the wings is perhaps the most variable 

 character, although, as before intimated, it is possible that this is to 

 some extent at least dependent upon age. The amount of dusky 

 brown color on the wings, and especially on the outer primaries and 

 their coverts, is another variable character. Many individuals have 

 the outer webs of the primaries extensively rufous chestnut at the 

 base, showing prominently in the closed wing, while in others this 

 color is scarcely or not apparent, the outer webs being more exten- 

 sively dusky brown. The under tail-coverts in both sexes, but more 

 particularly in the male, are subject to much variation as regards the 

 amount of paler tipping. Making due allowance for the greasy and 

 more or less discolored condition of many of the specimens, the 

 variation in color of the under parts is remarkably small in adult males, 

 the extremes being represented respectively by No. 2,393, Bishop 

 Collection ("Peninsular Florida," February 26, 1889), which is fully 

 as dark below as C. p. socorro'ensis, and No. 14,878, Bishop Collection 

 (Amelia Island, Florida, November 21, 1905), which compares 

 favorably with C. p. pallescens. The vast majority of specimens, 

 however, fall midway between these two extremes. There is decidedly 

 more variation in the color of the upper parts, numerous examples 

 being practically indistinguishable from C. p. pallescens in this respect. 

 The patch of brownish feathers on the occiput, usually well marked, 

 is occasionally merely indicated, the whole crown and nape being 

 practically "solid" plumbeous gray. 



Females vary much as do males in general intensity of color, some 

 being quite light, others much darker. Some females (if correctly 

 sexed) assume a decidedly vinaceous tinge beneath, as in the other
