BIRDS OF NEW MEXICO 
In winter—on December 19 and 20, 1918—at Deep Well Camp, 
northeast of Engle, when a terrible storm was raging, preceding the 
coldest weather in years, Mr. Ligon found Horned Larks gathered in 
great numbers, so hard pressed that they came for food about the door, 
into the sheds, and even into the house when they found a door open 
(MS).

MONTEZUMA HORNED LARK: Ot6coris alpestris occidentalis McCall 
Description.— Size of leucolaema but darker , more cinnamomeous or rufescent 
on entire upperparts, in summer especially noticeable on the back of the neck. 
Range. —In summer, from central Arizona to central New Mexico; in winter, 
south to central-western Texas, and northern parts of Chihuahua and Sonora. 
State Records. —When McCall spent the summer of 1850 in New Mexico, he 
found Horned Larks breeding near Santa Fe, and gave them the name of occidentalis. 
He met them here at the extreme northeastern limit of their range, whence they 
extend in the breeding season south to Albuquerque (Bailey). The subspecies 
extends from Santa Fe westward to Fort Wingate (Hcnshaw). On March 27,1885, 
one was taken by C. H. Marsh at Lone Mountain. During the winter the form 
spreads out over southern New Mexico south nearly to the southern boundary and 
east to Roswell (Gaut).—W. W. Cooke. 
CHIHUAHUA HORNED LARK: Otocoris alpestris aphrasta Oberholser 
Description. — Male: Length (skins), 5.7-6.2 inches, wing 3.9-4.1, tail 2.5-2.8, 
bill .4-5, tarsus .8. Female: Length (skins), 5.9-6 inches, wing 3.6-3.S, tail 2.2-2.5, 
bill .3-.5, tarsus 7.5-8. Much smaller, more uniform, and more reddish above than 
leucolaema; decidedly smaller and somewhat less deeply colored than occidentalis. 
Range. —Nearly or wholly resident in southeastern Arizona, the southwestern 
corner of New Mexico, and southeast through Chihuahua to Durango and southern 
Coahuila. 
State Records. —The breeding Horned Lark of the extreme southwestern part 
of New Mexico has been referred to aphrasta, the range of which lies for the most part 
in northern Mexico. It was taken May 27, 1892, at Dog Spring, Grant County 
(Mearns); at Rodeo, April, 1913 (Law and Brooks); and is probably the form found 
commonly at Apache (Anthony). It is probable that it is for the most part non- 
migratory.—W. W. Cooke. 
SASKATCHEWAN HORNED LARK: Ot6coris alpestris enthymia Oberholser 
* 
Description. — Male: Length (skins), 6.2-6.7 inches, wing 4-4.2, tail 2.6-2.9, 
bill .4-.5, tarsus .8-.9. Female: Length (skins), 5.8-6.1 inches, wing 3.7-4, tail 
2.3-2.6, bill .3-.4, tarsus .8. Like leucolaema but, in typical cases, paler; above much 
paler, more pinkish and grayish , eyebrow white, and throat usually very pale yellow. 
Range. —Breeds in Great Plains region from central Saskatchewan, eastern 
Montana, and central North Dakota south to central Kansas and northwestern 
Texas. In winter ranges south to southern Texas, and casually west to New Mexico, 
Utah, and Arizona.
