BIRDS OF NEW MEXICO 
Range. —Lower Canadian and Transition Zones from southeastern Arizona 
and extreme southwestern New Mexico south to Tepic and Zacatecas. 
State Records. —The only record for the Mexican Creeper in New Mexico 
is that of a specimen taken July 13, 1892, on the 'west side of the San Luis Mountains 
(Mearns). This is a Mexican 
subspecies, coming north reg¬ 
ularly to southern Arizona and 
undoubtedly occurring not rare¬ 
ly in the mountains of extreme 
southwestern New Mexico.— 
W. W. Cooke. 
General Habits. —In 
Arizona, Mr. Swarth found 
the Mexican Creeper a 
fairly common summer resi¬ 
dent in the higher pine 
regions, seldom descending 
below 7,000 feet. When the 
young came out, a down¬ 
ward movement began, and 
late in the summer they 
were found in the oak belt 
(1904, p. 60).

State Records. The Rocky Mountain Creeper is undoubtedly more common 
in summer in New Mexico than the few records of its occurrence would indicate. 
One was taken June 19, 1909, at 9,000 feet on Bear Ridge in the Zuni Mountains 
(Goldman); one seen early in June, 1900, at Cloudcroft (Bailey); and several there, 
July 23-August 1, 1909 (Green); while young birds were seen in July, 1907, near 
the top of the Chuska Mountains, about 9,000 feet (Gilman). [Young were found 
June 24, 1916, out of the nest north of Mount Taylor, at 7,500 feet. At 7,500 feet 
in Black Canyon, 32 miles southwest of Chloride, on June 28, 1920, adults were 
found feeding young in the nest (Ligon).] These, of course, represent breeding
