NOTES ON NORTH CAROLINA BIRDS — WETMORE 519 



from 3,700 feet at Blowing Eock, shot on August 8, 1940. In spring, 

 migrants were obtained at South Mills on April 14 and at Roseboro on 

 May 4. Fall specimens were taken on the Catawba River near 

 Catawba, September 29, and west of Statcsville, October 2, 3, and 5. 

 A male from Williston, taken on November 16, is apparently nearest 

 this race in color though small, as the wing measures 51.2 nun. only. 

 It appears that this form nests throughout western North Carolina 

 and that it is state-wide in occurrence in migration. 



GEOTHLYPIS TRICHAS TRICHAS (Linnaeus) : Maryland Yellowthroat 



This race apparently occurs in North Carolina only as a migrant 

 though it may breed near the coast in the extreme northeast, since 

 Duvall 2^ records one from near Pungo in southeastern Virginia. 



It is the smallest of those found here in wing measurement, and it 

 has the flanks more grayish, less brownish like the northern yellow- 

 throat {Geothlypis t. hrachidactyla) . 



In the series at hand there are two females ascribed to this race 

 taken in the Dismal Swamp area 7 miles west of South Mills, April 

 17 (wing 48.8 mm.) ; and near Sunbury, April 22 (wing 49.5 mm.). 

 It is probable that this subspecies may be found to be the breeding form 

 somewhere along the northern boundary of the State. 



GEOTHLYPIS TRICHAS TYPHICOLA Burleigh'*: Athens Yellowthroat 



This race, an intermediate between Geothlypis t. ignota of farther 

 south and triclias^ is marked by darker, browner coloration of back 

 and flanks, though not so dark as ignota. Though definitely an inter- 

 mediate it seems to occupy a wide enough range from Georgia to 

 southeastern Virginia to warrant recognition. In North Carolina 

 it is found as the breeding bird of the Coastal Plain, extending back 

 over the eastern section of the Piedmont. Birds from much of 

 this ai-ea are not so dark as those from farther south and tend to 

 range a little small, but they are too dark to be considered trichas. 



Two males and a female from near Southport, May 15 and 17, are 

 fairly typical in size and color. Of two taken near Roseboro on May 2 

 and 6, one is fairly typical and the other somewhat light in color. 

 A pair secured 11 miles east of Wadesboro on May 26 are definitely 

 intermediate both in size and color. 



Two males and two females, all immature, taken on Hogan Creek, 

 7 miles northeast of Reidsville, September 18, 19, and 22, have the size 

 of trichm but appear very dark, so that they are allocated as mter-
