The Mexican Jay is common in Coahuila. This species occupies various
habitats in the State and has been collected at stations ranging from
2100 to 9950 feet.

Miller (1955a:167) stated that the Mexican Jay was the most abundant
species of bird in the Sierra del Carmen. Burleigh and Lowery
(1942:196) remarked that specimens of _A. u. couchii_ were obtained "in
the area surrounding the summit of Diamante Pass." At no time did
Burleigh and Lowery (_loc. cit._) see this species below 6500 feet. The
Mexican Jay is restricted to the higher altitudes in southern Coahuila
but is more widespread in northern Coahuila. Dickerman saw Mexican Jays
in the Sierra del Pino on May 12, 1954; 16 mi. E and 18 mi. N Ocampo on
May 7, 1954; in the Sierra de la Madera on December 13, 1953; and 20
mi. S Ocampo on April 4, 1954.

Ridgway (1904:340) remarked that _Aphelocoma sieberii potosina_ Nelson
[=_A. u. couchii_ (Baird)] has been recorded in southern Coahuila, at
Carneros. Miller, Friedmann, Griscom, and Moore (1957:124) recorded _A.
u. couchii_ from Carneros, Nuevo Leon. I suspect (Ridgway, 1904:340 and
Goldman, 1951: map opposite p. 34) that the locality given by Miller,
Friedmann, Griscom, and Moore (_op. cit._) should be Carneros,
Coahuila, rather than C
