BIRDS OF WEST VIRGINIA — WETMORE 431 



GEOTHLYPIS TRICHAS TRICHAS (Linnaeus) 



Maryland Yellow-throat 



An immature male taken at the summit of Spruce Knob on 

 September 18 is of this race, as indicated by its wing measurement of 

 52.8 mm and by its dull coloration both above and below. It is 

 evidently a migrant in this locality. 



It is assumed that this is the breeding bird of extreme eastern West 

 Virginia, in the section east of the mountains, though specimens 

 need to be collected to estabhsh this. 



GEOTHLYPIS TRICHAS BRACHIDACTYLA (Swainson) 



Northern Yellow-throat 



Careful study of specimens indicate that this is the yellow-throat 

 that nests through the mountain area and the hill section to the 

 west, as well as in the northwestern portion. Whether true trichas 

 is found in the southwestern part of the State as a breeding bird 

 remains to be ascertained, as the only specimen at hand, from Four- 

 teen, taken April 28, is brachidadyla, though at that date it may have 

 been a migrant individual. One was taken at Zela, May 7; one at 

 Grantsville, May 20; one at Freed, Calhoun County, May 21; and 

 one at White Pine, May 25. In three males the wing ranges from 

 56.2 to 56.3 and the exposed culmen from 11.2 to 12.3 mm; and in 

 two females the wing is 52.0 and 54.7 and the exposed culmen 11.8 

 and 12.0 mm. 



In the mountains breeding specimens were taken in the Cranberry 

 Glades, on May 9 and between June 9 and 20, and on Middle Mountain 

 12 miles northeast of Durbin, June 29. Males have the wing 54.3 

 to 56.2 mm and the culmen from base 12.5 to 12.8 mm. Females 

 have the wing 49.3 to 51.7 and the culmen from base 11.4 to 11.7 mm. 



Fall specimens include a female from Cheat Mountain, 3 miles 

 west of Cheat Bridge, September 26 (wing, 52.3; culmen from base, 

 11.4 mm), and a pair from Spruce Knob, September 18 and 21 (male, 

 wing 56.2, culmen from base 12.5 mm; female, wing 52.0, cidmen 

 from base 11.2 mm). 



All these specimens are brighter green above and more extensively 

 yellow below when compared with typical trichas, the colors being 

 especially rich in fall plumage. 



This marks a definite southern extension of the range of the northern 

 yellow-throat from what is given in the fourth edition of the A. O. U. 

 Check-list of North American Birds, 1931, p. 296.
