BIRDS OF NEW MEXICO 
HOOVER WARBLER: Dendroica coronata hodveri (McGregor) 
Description. — Type: Male: wing 3 inches, tail 2.3. Adult male in spring and 
summer: Crown , rump , and sides of breast with yellow patches; upperparts bluish gray, 
back streaked with black; tail black, two or three outer pairs of feathers with white 
patches near tip; wings with two white bars, throat white , breast black, streaked and 
tipped with white, center of belly white, flanks streaked. Adult male in fall and 
winter: Crown and back grayish brown , crown patch partly concealed, back indis¬ 
tinctly streaked; rump and tail as in spring, wings with brownish bars; underparts 
white, breast washed with brown , yellow patches and streaking less pronounced than 
in spring. Adult female in spring and summer: Similar to summer male but smaller 
and color patches smaller and duller, the upperparts tinged with brown. Adult 
female in fall and winter: Similar to winter male but upperparts browner, color 
patches smaller, anterior and lateral underparts pale buffy brown, median parts dull 
yellowish white. 
Comparisons. —The Hoover Warbler, rare in New Mexico, should not be con¬ 
fused with the common Audubon Warbler and can easily be recognized by its white 
throat. 
Range. —Breeds in Hudsonian and Canadian Zones from tree limit in north- 
central Alaska and northwestern Mackenzie south to Ontario, central Alberta, and 
northern British Columbia; winters from California and Arizona south to southern 
Lower California, Vera Cruz, and Mexico. Recorded from New Mexico in migration. 
State Records. —In the spring of 1904 the Hoover Warbler was found fairly 
common in migration at Rinconada (Surbcr); and specimens were taken from April 
16 to May 2. This seems to be the only certainly known occurrence of the species in 
the State. Doctor Henry says: “Very abundant everywhere during the months of 
April and October. First observed at the Mimbres April 2.“ But as he makes no 
mention of auduboni in any of his lists it is evident that his coronata was really the 
latter species.—W. W. Cooke. 
General Habits.— The large tame, restless Hoover Warbler, the 
western form of the Myrtle Warbler, with white throat and yellow 
rump, “ranges from the ground and low bushes to tree-tops in scrub 
lands and half open woods, avoiding the deep forests.” 
AUDUBON WARBLER: Dendroica auduboni auduboni (J. K. Townsend) 
Description. — Male : Length (skins) 4.S-5.4 inches, wing 2.0-3.2; tail 2.1-2.4; 
bill .3-.4; tarsus .7-.8. Female: Length (skins) 4.8-5 inches, wing 2.9-3.1; tail 2.1- 
2.3; bill .3-.4; tarsus .7-.8. A dull male in spring and summer: Crown, rump , throat , 
and sides of chest, yellow; upperparts bluish gray; back streaked with black; tail and 
wings black, tail with inner webs of four or five outer feathers white near tip; wings

and sides from white of belly. Adult male in fall and wilder: Gray of upperparts 
obscured by brown wash, wing markings tinged with brown, black of underparts 
mostly overlaid by brownish edgings of feathers. Adult female in spring and summer: 
Similar to the summer male but duller and color patches restricted; upperparts 
usually tinged with brown, wings with dull bars. Adult female in fall and winter: 
Similar to winter male but smaller and still duller, color patches and streakings 
restricted and duller. Young injuvenal plumage: Upperparts brown, thickly streaked 
with black and white; underparts white, streaked with black, grayish white below. 
Comparisons. —The Audubon and Hoover Warblers can be distinguished from 
all other Warblers by the yellow patches on crown, rump, and sides of breast, and
