Birds from Coahuila, Mexico

by Emil K. Urban

Archilochus colubris (Linnaeus).—Friedmann, Griscom, and Moore (1950:180) remarked that the Ruby-throated Hummingbird is a moderately common migrant, wintering from sea level to 9350 feet throughout México, except in a few states. The only published record of a specimen of this hummer in the State is of a male taken on April 22 in a small arroyo twenty miles west of Saltillo (Burleigh and Lowery, 1942:191).

*Archilochus alexandri (Bourcier and Mulsant).—Specimens examined: total 2: ♂ 31035 from the Río Grande (=17 mi. S Dryden, Terrell County, Texas, in Coahuila), 600 ft., March 18, 1952; and ♂ 32052 from 2 mi. S, 11 mi. E Nava, 810 ft., June 16, 1952.

Miller (1955a:165) stated the Black-chinned Hummingbird was common in the desert area at the base of the mountains of the Sierra del Carmen, and that Marsh, on July 25, obtained this hummingbird "near Piedra Blanca (Conejo)." Burleigh and Lowery (1942:191) obtained a female in an arroyo about twenty miles west of Saltillo on April 22.

**Selasphorus platycercus platycercus (Swainson).—Specimens examined: total 2: ♂ 31583 from 20 mi. S Ocampo, 6500 ft., April 4, 1954; and ♀ 32673 from 13 mi. E San Antonio de las Alazanas, 9950 ft., July 6, 1955.

Miller (1955a:165) indicated that the Broad-tailed Hummingbird was fairly common in the Sierra del Carmen. According to Burleigh and Lowery (1942:191) this species is not uncommon in the pine woods bordering the summit of Diamante Pass; they saw the bird between 4900 and 10,000 feet.

*Eugenes fulgens fulgens Boucard.—Miller (1955a:165) obtained a male Rivoli's Hummingbird on Loomis Peak, 8800 feet, on April 11 in the Sierra del Carmen.

**Lampornis clemenciae clemenciae (Lesson).—Specimens examined: total 2: ♂ 31036 from 26 mi. W Santa Teresa, 7050 ft., April 5, 1952; and ♀ 32668 from 13 mi. E San Antonio de las Alazanas, 9950 ft., July 6, 1955.

The Blue-throated Hummingbird occurs between 5000 and 9950 feet in Coahuila. Miller (1955a:165) remarked that it was found in canyon bottoms, "whether at 7500 feet among the rocky slopes, oaks, and white pines ... or at 5000 feet in the madrone, maples, elms, and basswoods...." No. 32668, was obtained in a Douglas fir-pine-aspen association at 9950 feet.

[Amazilia yucatanensis chalconota Oberholser.—The Buff-bellied Hummingbird seems to be uncommon in Coahuila. Friedmann, Griscom, and Moore (1950:172) and the AOU Check-list Committee (1957:306) stated that this hummingbird occurs in Coahuila.]

Megaceryle alcyon alcyon (Linnaeus).—Miller (1955a:165) saw a Belted Kingfisher at Carboneras Canyon in the Sierra del Carmen. Miller, Friedmann, Griscom, and Moore (1957:15) stated that one specimen of M. a. alcyon was obtained in Coahuila on November 14.
