_Coccyzus erythropthalmus_ (Wilson).--Miller (1955a:163) reported a migrant Black-billed Cuckoo taken in the maples and basswood near a water hole in the bottom of Boquillas Canyon in the Sierra del Carmen, 5200 feet, on April 22. Friedmann, Griscom, and Moore (1950:132) reported that this cuckoo is presumably a regular transient in México, but generally overlooked.
*_Geococcyx californianus_ (Lesson).--_Specimen examined:_ one, [Female] 32049, from 8 mi. N, 2 mi. W Piedras Negras, June 18, 1952.
Miller (1955a:163) heard several Roadrunners calling at Boquillas Canyon in the Sierra del Carmen, where he obtained two females. Burleigh and Lowery (1942:190) stated that the species proved to be "unexpectedly scarce" and was noted but once by them on April 22 when a single bird was observed in "the open desert west of Saltillo." Sutton and Burleigh (1939a:30) noted that the Roadrunner was not common anywhere in southern Coahuila; they obtained one female at San Pedro on January 29. The size of the largest ovum (15 mm. in diameter) of No. 32040 indicates that this species breeds in Coahuila.
*_Crotophaga sulcirostris sulcirostris_ Swainson.--_Specimen examined:_ one, [Female] 32039, from 2 mi. S, 3 mi. E San Juan de Sabinas, June 22, 1952.
No. 32039, obtained by Harrison B. Tordoff in a cypress woods along the shore of a lagoon, provides the first record of the Groove-billed Ani in Coahuila. The size of its largest ovum (10 mm. in diameter) and the date indicate breeding by this species in Coahuila.
**_Tyto alba pratincola_ (Bonaparte).--The Barn Owl seems to be uncommon in Coahuila. To my knowledge, there are two records of the Barn Owl in Coahuila. Ridgway (1914:607) recorded this owl at the "head of Las Vacas Creek." Miller (1955a:163) heard the Barn Owl at 5000 feet in the oak belt on April 25 in the Sierra del Carmen.
*_Otus asio suttoni_ Moore.--_O. a. suttoni_ is found in the higher country of the Sierra del Carmen and western Coahuila. Miller (1955a:163) stated that Screech Owls were common in groves of oaks both at 7000 feet and 5000 feet in the Sierra del Carmen, and remarked that his series from the Sierra del Carmen matched well a series of _suttoni_ from Chihuahua and Durango. Miller (1955a:163-164) also stated that Marsh took an adult at Jardín del Sur on August 28 and said that the specimen from the Sierra del Carmen referred to as _cineraceus_ by Marsh and Stevenson (1938:286) agreed well with his series of _suttoni_. _O. a. suttoni_ probably occurs no farther east than the Sierra del Carmen.
