The Sparrow Hawk is locally common in Coahuila. Miller (1955a:162)
noted the species occasionally in the lower canyon areas of the Sierra
del Carmen at 5000 feet from April 20 to 28. Dickerman saw two Sparrow
Hawks in the Sierra del Pino on May 12, 1954. Sutton and Burleigh
(1939a:27) took a male at La Rosa on January 30 that was typical for
_F. s. sparverius_. Burleigh and Lowery (1942:188) noted Sparrow Hawks
almost daily about Saltillo and infrequently in the open valley south
of Diamante Pass; they took a female at Saltillo on April 22 that was
assigned to _F. s. sparverius_.

The Bobwhite is locally common in northeastern Coahuila. Aldrich and
Duvall (1955:18) indicated that _C. v. texanus_ has been recorded from
two separate localities in northeastern Coahuila and from several
localities in Texas along the Rio Grande. Findley saw Bobwhites 2 mi. S
and 3 mi. E San Juan de Sabinas on June 22, 1952. The specimens of
Bobwhite from 3 mi. W and 1 mi. S San Geronimo seem to extend the known
range of _texanus_ nearly 100 miles west. The sizes of the testes (11,
16, 15, 15 mm.) of Nos. 29408, 32032-32034, respectively, indicates
breeding by the Bobwhite in Coahuila.
