n-tailed Towhee is a common migrant and winter visitant in
Coahuila; the species has been found at several localities. Miller
(1955a:175) noted several migrants "each day in the last week of
April ... at the mouth of Boquillas Canyon" of the Sierra del Carmen.
Burleigh and Lowery (1942:207) noted the species "in an arroyo in the
open desert country about twenty miles west of Saltillo on April 22."
Miller, Friedmann, Griscom, and Moore (1957:351) listed the
Green-tailed Towhee from 12 mi. W Saltillo on September 28 and from
Sabinas.

*_Piplio erythrophthalmus gaigei_ Van Tyne and Sutton.--_Specimens
examined:_ total 3: [Female] 31102 from Fortin (=33 mi. N, 8 mi. W San
Geronimo), 3300 ft., March 28, 1952, weight, 38.8 gms.; [Male] 35412
(skeleton only) from Sierra del Pino (=5 mi. W, 3 mi. S Acebuches),
6200 ft., May 15, 1954, testes enlarged, weight, 34 gms.; and [Male]
31593 from 17 mi. S Ocampo, 5300 ft., April 7, 1954, weight, 38 gms.

The Rufous-sided Towhee is locally common in Coahuila; _P. e. gaigei_
is present in northern Coahuila. Miller (1955a:175) remarked that
"between 6800 and 7500 feet these towhees were sparsely distributed in
areas of scattered low ceanothus and hawthorne, chiefly in canyon
bottoms, but also on slopes where ceanothus was intermingled with
downed timber and young pines." He (_loc. cit._) indicated that the
adult obtained by Marsh from Vivoras Canyon on August 25 was _P. e.
gaigei_ rather than _P. maculatus montanus_ (see also Sibley,
1950:127). Dickerman saw Rufous-sided Towhees in the Sierra de la
Madera on December 13, 1953. I have referred Nos. 31102 and 31593 to
_gaigei_ although both are close to _orientalis_. The size of the
testes (14x8 mm.) of No. 31593 suggests breeding.

*_Piplio erythrophthalmus orientalis_ Sibley.--_Specimens examined:_
total 3: [Male] 32154 from 7 mi. S, 4 mi. E Bella Union, 7200 ft., June
25, 1952; [Male] 33223 (skeleton only) from 13 mi. E San Antonio de las
Alazanas, 9950 ft., July 6, 1955; and [Male] 31630 from Mesa de Tablas,
8600 ft., January 15, 1954, weight, 46 gms.

This subspecies of the Rufous-sided Towhee occurs in southeastern
Coahuila. Burleigh and Lowery (1942:207) stated that it "was limited in
its distribution to the mountain sides ... [and was] noted in the
arroyos at the base of the mountains and from there up to about 8,000
feet." These authors identified their specimens from Diamante Pass and
from Saltillo as _Pipilo maculatus gaigei_
