Virginia’s Warbler. Vermivora virginie. 
A.O.U. Checklist no 644—Colorado Records—Aiken 72, p. 196; 
Henshaw 75, p. 189 ; Minot 80, p. 226; Allen & Brewster 83, p. 155 ; 
Drew 85, p. 15; Cooke 97, pp. 113, 218 ; 04, p. 37 ; Henderson 03, p. 237; 
09, p. 239 ; Warren 06, p. 23 ; Chapman 07, p. 98 ; Rockwell 08, p. 176. 
Description.—Male—General colour above dark slaty-grey; crown 
with partly concealed patch of dark chestnut; a conspicuous white 
orbital ring ; rump and upper tail-coverts, a patch on the breast paling 
off towards the throat, and under tail-coverts bright yellow ; wings 
and tail dusky, unmarked ; below pale grey except for the yellow; 
iris brown, bill horn, paler on the lower mandible, legs dusky horn. 
Length 4-30; wing 2-5 ; tail 1-75 ; culmen -40; tarsus -72. 
In fall and winter the plumage has a much browner tinge, the yellow 
breast-patch is less conspicuous and the crown-patch completely con- 
cealed by the long grey tips of the feathers. The female resembles 
the male, but is duller in colour generally, especially as regards the 
chestnut of the crown and the yellow patches, all of which are more 
restricted. The young bird has the wing-coverts tipped buffy, forming 
two obscure wing-bars, and at first hardly any traces of chestnutor yellow. 
Distribution.—Breeding in the Rocky Mountains region from Colorado 
and Nevada south to New Mexico and Arizona; in winter through 
Mexico as far south as Guerrero. 
In Colorado Virginia’s Warbler is of common occurrence along the 
eastern foothills of the mountains up to an elevation of about 7,500
