NOTES ON BIRDS OF KENTUCKY — WETMORE 551 



achrusterus^ having a wing measurement of 12T.4 mm. and the color 

 of the lower surface slightly paler than typical migratorius (though 

 above it is dark). Two skins in spotted juvenal plumage, fully 

 grown, from Quincy, July 12, have the long wing of the northern race. 

 The following skins were taken when northern migrants may have 

 been present : South Carrollton, October 22 ; Golden Pond, November 

 3; Canton, October 31; Brandenburg, April 29 (a pair of fully typical 

 northern birds, possibly breeding) ; Brownsville, November 10; Ghent, 

 October 14; Berea, October 6. 



TURDUS MIGRATORIUS ACHRUSTERUS (Batchelder) : Southern Robin 



An adult female shot at 4,100 feet elevation on Black Mountain, 

 4 miles southeast of Lynch, June 21, has the wing 120.7 mm. and the 

 coloration very pale, being typical of the southern form. This 

 should be the bird that nests along the southern border of Kentucky, 

 but this can be ascertained only by further collecting. 



It may be noted that an adult male from 9 miles east of Williamson, 

 W. Va., collected on July 8, 1938, is typical achrusterus. 



HYLOCICHLA MUSTELINA (Gmelin) : Wood Thrush 



The wood thrush, distributed in summer throughout Kentucky, was 

 obtained as follows: Uniontown, May 13; Brandenburg, April 28 

 and May 2"; Rock Haven, April 26; Log Mountain, near Middlesboro, 

 September 23; 4,100 feet elevation on Black Mountain near Lynch, 

 June 21; Belfry, Pike County, July 4 and 9 (the last an immature 

 bird not quite grown) ; and Quincy, July 12. 



HYLOCICHLA GUTTATA FAXONI Bangs and Penard : Eastern Hermit Thrush 



Specimens were taken as follows: Madisonville, October 25; 

 Brownsville, November 8; Roundhill, November 9; Ghent, October 

 12 and 14; Morehead, October 8. 



HYLOCICHLA USTULATA SWAINSONI (Tschndi) : Eastern Olive-backed Thrush 



Two were taken in fall migration at 2,800 and 2,900 feet elevation 

 on Log Mountain, 7 miles west of Middlesboro, on September 17 

 and 19. 



HYLOCICHLA USTULATA ALMAE Oberholser: Western Olive-backed Thrush 



That this form, described originally from the Great Basin, is truly 

 distinct has been indicated recently by van Rossem^ and by Ober- 

 holser ^ on the basis of more grayish, less brownish dorsal coloration. 

 As a migrant this bird occurs casually to the eastward, and it is of
