A Northern Breeding Record for the Mexican Black Hawk in New Mexico
A Northern Breeding Record for the Mexican Black Hawk in New Mexico.-The most northern breeding record for the Mexican Black Hawk (Buteogallus anthracina) in New Mexico has.been in the vicinity of the town of Glenwood, situated in the southwestern corner of the state. Mrs. Bailey (Birds of New Mexico, 1928:176) reported that “Mr. Ligon has seen specimens taken on the Gila River east of Cliff, where he is quite sure that they nest; while Mr. Kellogg has a specimen taken on the Gila in the summer of 1918 and found a pair nesting in a cottonwood grove on the Gila, 20 miles west of Silver City, May 29, 1921.” Mr. Ligon has subsequent nesting records near Glenwood, more to the north, and Chauncie Snyder of Silver City found a nest in the summer of 1956 at the junction of the west and middle forks of the Gila River just east of Glenwood.
Between May 15 and August 10, 1956, Elmo Traylor of the New Mexico Game and Fish Department had a Mexican Black Hawk nest under observation in Mills Canyon, which opens into the Canadian River in northeastern New Mexico (fig. 1). The nest site is approximately seven miles west of Mills. This nesting station is approximately 162 miles north and 234 miles east of Glenwood. The nest was 60 feet up in a ponderosa pine and it contained one young in June and July. The young one left the nest by July 26. The adults and young had left the general area by August 10, 1956.-WAYNE H. Born, New Mexico Department of Game and Fish, Santa Fe, New Mexico, September 28, 1956.
