Rufous-bellied Chachalaca (Ortalis wagleri) - HBW 2, p. 344

French: Ortalide à ventre marron German: Rotbauchguan Spanish: Chachalaca Ventricastaña
Other common names: Wagler's Chachalaca

Taxonomy: Ortalida Wagleri G. R. Gray, 1867, California and Mexico.
Forms superspecies with O. poliocephala, of which formerly considered a race; a few cases of hybridization in NW Jalisco were interpreted as proof of a narrow zone of intergradation in W Jalisco and W Colima, where intermediates were even considered a different race, lajuelae; cases of hybridization may have resulted from escapes of imported O. poliocephala (see page 312). Population of Sonora was considered a different race, griseiceps, but not usually recognized. Monotypic.

Distribution: W Mexico, from S Sonora S to NW Jalisco.
