The Broad-billed Hummingbird Cynanthus latirostris is a fairly common and widespread species in Mexico whose range barely extends into the southwestern United States. It is a summer visitor from southwestern New Mexico (Cloverdale Mountains) to south central Arizona (Baboquivari Mountains) (A.O.U. Check-list, 1957); it has straggled as far east as west Texas (Chisos Mountains) (R. H. Wauer, pers. comm.). In Arizona it occurs between mid-March, occasionally the first week of March, to mid-September, occasionally to 1 October; one remained near Tucson to 4 December 1960 (Phillips et al., The Birds of Arizona, 1964).
