THRUSHES, BLUEBIRDS, ETC.: HERMIT THRUSH 571 
hua, Sonora, and Lower California; in migration east to eastern Oregon, Nevada, 
Arizona, New Mexico, and Texas. 
State Records. —Four forms of the Hermit Thrush occur in New Mexico; 
only one of them, Hylocichla guttata auduboni, breeding in the State, while the others, 
H. g. guttata , H. g. nana, and IJ. g. sequoiensis, come as migrants or as winter resi¬ 
dents. The Alaska Hermit Thrush, II. g. guttata , as its name implies, breeds mainly 
in Alaska, though it winters south to northern Mexico. During migration a few 
pass through New Mexico, where one was taken October 12, 1883, near Willis 
(HenBhaw); another on October 10, 1908, was taken in the Chuska Mountains 8,800 
feet (Birdseye); one October 19,1906, in the Mogollon Mountains, 8,500 feet (Bailey); 
others in the Powder Horn Canyon of the Mimbres River, October 6, 1908. (Berg- 
told); and the San Luis Mountains September 29, 1893 (Mearns).—W. W. Cooke. 
AUDUBON HERMIT THRUSH: Hylocichla guttata auduboni (Baird) 
Description. — Length: 7.5-8.2 inches, wing 3.6-4.3, tail 2.9-3.4, bill .5-6. 
Adults in spring and summer: Upperparts light grayish brown, rump), upper tail 
coverts and tail fulvous, in decided contrast to back; underparts white, shaded with 
grayish olive on sides, throat immaculate but breast tinged with bufTy and marked 
with numerous large dusky spots; orbital ring buffy. Adults in fall and winter: 
Colors stronger, olivaceous of upperparts more reddish brown (back still strongly 
contrasting with tail), buffy wash of underparts more pronounced. Young: Upper- 
parts largely marked with buffy, clubbed streaks, underparts spotted and more or 
less barred. 
Comparisons. —The Audubon Hermit Thrush can be distinguished from the 
other Hermit Thrushes by its larger size. 
Range. —Breeds in Canadian and Upper Transition Zones from British Columbia 
and Montana south to New Mexico and Arizona; winters in western and central 
Texas and south over Mexican tableland to Guatemala. 
State Records. —The higher parts of the New Mexico mountains arc occupied 
in summer by the Audubon Hermit Thrush. It was common from 11,000 to 11,600 
feet at the foot of Pecos Baldy, young being out of the nest July 23, 1903; and it was 
still common at 11,600 feet the middle of August. The next year it was common 
July 19-August 8 at 10,700 feet in the mountains north of Taos (Bailey). These 
altitudes mark the upper limit of the breeding range. It breeds commonly at 9,000 
feet on Mount Sedgwick in the Zuni Mountains (Goldman); at Clouderoft, 9,000 
feet (Green); [was taken June 28, 1919, 40 miles northeast of Santa Fe at 8,500 feet 
(Ligon); and was common in the Sangre de Cristo Mountains from 7,500 feet to 
timberline; fresh eggs being found June 10-July 1 (Jensen, 1922)]; breeding down to 
8,000 feet in the yellow pine belt of the San Mateo Mountains (Hollister); in the 
Capitan Mountains, July 10, 1902 (Gaut); the Chuska Mountains (Gilman); at 
Willis, 7,800 feet, June 3, 1901 (Birtwell); on Pueblo Creek 7,000 feet, near Taos, 
July 11, 1904 (Bailey). Thus its breeding range extends from about 7,000 to 12,000 
feet, but it nests most commonly at 9,000-11,000 feet. (One was taken and several 
observed May 8, 1920, at the north end of the Animas Mountains; two nests were 
found in the Black Range, in canyon beds, one with young 8 miles southwest of 
Chloride, at 6,800 feet, June 25,1920, and one with eggs in Circle Seven Canyon, 16 
miles south of Chloride, at 7,000 feet, July 6, 1920 (Ligon).] 
Apparently all the summer birds of this form go south of New Mexico for the 
winter. The latest dates on which it was certainly identified were September 10, 
1909, at 9,000 feet in Monica Canyon of the San Mateo Mountains (Goldman); and
