NOTES ON BIRDS OF KENTUCKY WETMORE 555 



The Key West vireo, Vireo griseus maynardi Brewster, differs from 

 the bird of the north in grayer dorsal color, in paler and more restricted 

 yellow on sides and flanks, and in slightly larger bill. Breeding speci- 

 mens from northern Florida and the Gulf States to Louisiana and 

 north to South Carolina in series average very slightly duller yellow 

 on the sides and flanks than those from farther north. The difference 

 is slight and is appreciable only in part of the specimens I have seen, 

 about one-half of those examined being identical from the two areas. 

 In view of the slight amount of the difference and of its variation it 

 does not seem to be practicable to recognize two races in this northern 

 area, so that all the birds of the Eastern United States north of south- 

 ern Florida should in my opinion be called Vireo griseus grisem. The^ 

 duller birds of the south merely represent intergrades toward the 

 duller colored race maynardi of extreme southern Florida. 



VIREO FLAVIFRONS Vieillot: Yellow-throated Vireo 



Specimens were obtained during the breeding season at Hickman on 

 May 21, Kocky branch on June 13, and Monticello on June 14. Several 

 were found during the fall migration on the slopes of Log Mountain 

 on September 20, 24, and 25. 



VIREO SOLITARIUS SOLITARIUS (Wilson) : Blue-headed Vireo 



One was shot near Morehead on October 8 and another near Sacra- 

 mento on October 17. These are the only records made pertaining to- 

 the northern race of this bird. 



VIREO SOLITARIUS ALTICOLA Brewster: Mountain Vireo 



On Black Mountain, 4 miles southeast of Lynch, the mountain vireo 

 was common above 3,800 feet, so that six specimens were collected 

 between June 23 and 28. These all have the dark dorsal coloration and 

 longer wing of this southern form. On Log Mountain, 7 miles west of 

 Middlesboro, we found two on September 24, and later Perrygo col- 

 lected another on September 27. These three birds are still in partial 

 molt on the head and body and are believed to be representative of the 

 nesting birds of this area. The range of this form in Kentucky is- 

 necessarily decidedly limited. 



VIREO OLIVACEUS (Linnaeus) : Red-eyed Vireo 



Common and widely distributed, specimens of the red-eyed vireo 

 were collected as follows: Hickman, May 20; Uniontown, May 10; 

 Waverly, May 11; Brandenburg, April 20 and 27; Coopersville, June 

 3; Rocky Branch, June 7; Log Mountain, near Middlesboro, Septem- 

 ber 17 and 20; Belfry, Pike County, July 4 and 6; 4,000 feet elevation 

 on Black Mountain, near Lynch, June 27 ; Quincy, July 12. In fall the 

 last one was recorded near Mount Vernon on October 5.
