, March 29, 1952; and
[Female] 32059 from 7 mi. S, 4 mi. E Bella Union, 7200 ft., June 25,
1952.

Say's Phoebe occurs commonly in Coahuila. Miller (1955a:167) obtained a
female with an active brood patch in Boquillas Canyon of the Sierra del
Carmen, and remarked that Marsh took a juvenile on September 2 at El
Rincon. Sutton and Burleigh (1939a:33) saw this phoebe several times in
southern Coahuila and obtained a male "near San Pedro" on January 29.
Burleigh and Lowery (1942:193) recorded this species as "a common
breeding bird both on Diamante Pass and on the arid plateau around
Saltillo." No. 32059 was a juvenile.

_Empidonax traillii brewsteri_ Oberholser.--Amadon and Phillips
(1947:578) look a Traill Flycatcher of the subspecies _brewsteri_ at
Las Delicias on August 11.

_Empidonax minimus_ (Baird and Baird).--_Specimen examined:_ one,
[Male] 31470, from Sierra del Pino (=5 mi. S, 3 mi. W Acebuches), 6200
ft., May 13, 1954.

Amadon and Phillips (1947:578) obtained two Least Flycatchers at Las
Delicias on August 12. Dickerman took No. 31470 in pine-oak vegetation.

_Empidonax hammondii_ (Xantus).--_Specimen examined:_ one, sex ? 31657,
from the north slope of Sierra Guadalupe (=11 mi. S, 7 mi. W General
Cepeda), 7800 ft., April 20, 1953.

No. 31657 is similar to _E. wrightii_ (Wright's Flycatcher); however,
the outmost (tenth) primary is equal to or slightly larger than the
fifth primary. Yet, the underparts of No. 31657 are darker and more
uniform in coloration than those of typical representatives of _E.
wrightii_. Miller, Friedmann, Griscom, and Moore (1957:88) stated that
Hammond's Flycatcher is "transient" in Coahuila. Burleigh and Lowery
(1942:193-194) reported that _E. hammondii_ was the most prevalent of
the small flycatchers in southeastern Coahuila. They (_loc. cit._)
obtained specimens of this flycatcher from the Chorro del Agua and
Diamante Pass. Miller (1955a:167) characterized _E. hammondii_ as a
common migrant, "chiefly in stands of low oaks in the pine-oak belt but
also occasionally in the desert scrub" of the Sierra del Carmen.

_Empidonax wrightii_ Baird.--Amadon and Phillips (1947:578) reported
one Wright's Flycatcher from Las Delicias. Miller (1955a:167) stated
that this species was a common migrant and occurred chiefly in the
lower oak belt and in the desert scrub. Sutton and Burleigh (1939a:34)
obtained specimens of _E. wrightii_ from San Pedro on January 29.
