The Sage Thrasher seems to be a winter visitant to Coahuila. Miller,
Friedmann, Griscom, and Moore (1957:173) recorded the species in
November from 8 mi. S Cuatro Cienegas.

*_Turdus migratorius propinquus_ Ridgway.--_Specimen examined:_ one,
[Female] 31073 (skeleton only) from 4 mi. W Hacienda La Mariposa, 2300
ft., March 24, 1952.

Burleigh and Lowery (1942:200) stated that "the Robin apparently breeds
rather sparingly on the higher ridges" in southeastern Coahuila. They
collected a pair "in the open pine woods just below the summit of
Diamante Pass" on April 15 and noted another at the Chorro del Agua on
April 19.

**_Ridgwayia pinicola_ (Sclater).--_Specimen examined:_ one, [Male]
31619, from 5 mi. W, 22 mi. S Ocampo, 6000 ft., December 15, 1953,
weight, 88 gms.

The Aztec Thrush is rare in Coahuila. Van Hoose (1955:302) remarked
that No. 31619, the skull of which was incompletely ossified,
"represents the northernmost record for this species, which was
previously unknown in Coahuila."

_Hylocichla guttata guttata_ (Pallas).--_Specimens examined:_ total 2:
[Male] [Male] 31074-31075 from 4 mi. W Hacienda La Mariposa, 2300 ft.,
March 25 and 26, 1952, weights, 25, 21 gms.

The Hermit Thrush is a common migrant or winter visitant in Coahuila.
_H. g. guttata_ has been reported from northern Coahuila. Miller
(1955a:171) observed _H. g. guttata_ (and _H. g. auduboni_) in the
Douglas fir and pine-oak belts and in the lower levels in the oaks at
the foot of the Sierra del Carmen. Burleigh and Lowery (1942:200) noted
_H. g. guttata_ "in small numbers in the open woods surrounding the
summit of Diamante Pass, and at infrequent intervals in the arroyos on
the arid plateau near Saltillo."

_Hylocichla guttata sequoiensis_ (Belding).--Ridgway (1907:45) recorded
this subspecies of Hermit Thrush from Sierra Guadalupe in April.
However, Miller, Friedmann, Griscom, and Moore (1957:188) suggest that
the material on which this identification was based needs
redetermination.

_Hylocichla guttata auduboni_ (Baird).--_Specimens examined:_ total 3:
[Female] 31488 from Sierra del Pino (=5 mi. S, 3 mi. W Acebuches), May
12, 1954, weight, 25 gms.; [Female] 31076 (skeleton only) from Fortin
(=33 mi. N, 1 mi. E San Geronimo), 3300 ft., March 28, 1952; and
[Female] 31077 (skeleton only) from 26 mi. W Santa Teresa, 7050 ft.,
April 4, 1952.

Miller (1955a:171) found this subspecies of Hermit Thrush wintering
with _H. g. gu
