nta Teresa, 7050 ft., April 5, 1952; and [Female] 31668 from
Sierra Guadalupe, Canyon d. Meco (=10 mi. S General Cepeda), 6500 ft.,
April 23, 1953.

The Acorn Woodpecker in Coahuila is common in the oak and pine-oak
belts, from 4950 to 8000 feet. Miller (1955a:166) stated that the Acorn
Woodpecker in the Sierra del Carmen was an abundant and conspicuous
bird throughout the oak and pine-oak belts, from 5000 to 8000 feet.
Dickerman saw two Acorn Woodpeckers in the Sierra de la Madera on
December 13, 1953, and four 20 mi. S Ocampo, 6000 feet, on April 4,
1954. Breeding of _M. f. formicivorus_ was reported by Miller (_loc.
cit._) who took females nearly ready to begin laying; one of our
specimens (No. 29423) had enlarged testes (11 mm.).

_Sphyrapicus varius varius_ (Linnaeus).--_Specimen examined:_ one,
[Female] 31649, from the north foot of Sierra Guadalupe (=10 mi. S, 5
mi. W General Cepeda), 6400 ft., April 19, 1953.

Miller (1955a:166) reported this Yellow-bellied Sapsucker as a winter
visitant or migrant in the Sierra del Carmen. Burleigh and Lowery
(1942:192) took a female _S. v. varius_ at the summit of Diamante Pass
on April 14. Ridgway (1914:275) listed _S. v. varius_ from Sierra de
Guadalupe.

_Sphyrapicus varius nuchalis_ Baird.--Miller (1955a:166) reported this
Yellow-bellied Sapsucker as "indeed common" in the Sierra del Carmen,
and indicated that both _S. v. nuchalis_ and _S. v. varius_ were "found
only at the upper levels in the pine-oak formation and usually in
relatively dense clumps of trees in the canyon bottoms." Ridgway
(1914:280) listed _C. v. nuchalis_ from Rio Sabinas.

**_Dendrocopos villosus icastus_ (Oberholser).--Miller, Friedmann,
Griscom, and Moore (1957:39) remarked that this subspecies of the Hairy
Woodpecker occurs, in northwestern Mexico, from eastern Sonora,
Jalisco, Chihuahua, Durango, Zacatecas to southern Coahuila. Ridgway
(1914:222) stated that _D. v. icastus_ occurs in Coahuila at Carneros
and Sierra de Guadalupe, the former being the easternmost known
locality for the subspecies.

**_Dendrocopos villosus intermedius_ (Nelson).--_Specimens examined:_
total 2: [Male] 32701 from 13 mi. E San Antonio de las Alazanas, 9950
ft., July 6, 1955; and [Female] 31604 from 2 mi. E Mesa de Tablas, 8500
ft., January 15, 1954.

In northeastern Mexico this subspecies, according to Miller, Friedmann,
Griscom, and Moore (1957:39), occurs in Guanajuato, San Luis Potosi,
Hidalgo, Nuevo Leon, an
