Sierra
Madre Occidental
Description: The Sierra Madre Occidental mountain
range runs northwest to southeast parallel to the Pacific Coast from
the Mogollon Rim and isolated mountain ranges in southeastern Arizona
and southwestern New Mexico through Sonora to central Mexico, where
it connects with the Sur del Altiplano Mexicano. It is characterized
by high elevations and a complex topography with the presence of oak-pine,
pine, and fir forests along the mountain range and of semiarid scrub
habitats on eastern slopes. In Mexico there are more than 20 IBAs in
this BCR, including El Carricito, a remnant of old-growth pine-oak forest
and habitat for the presumably extinct Imperial Woodpecker and other
important species, such as Golden Eagle, Military Macaw, Thick-billed
Parrot, and Eared Trogon. Other priority landbirds of this BCR in Mexico
are the Rose-throated Becard, Spotted Owl, Golden Eagle, and Peregrine
Falcon. Among the species whose range extends into the United States
in this region, highest priorities include the Red-faced Warbler, Stricklands
Woodpecker, and Montezuma Quail. Riparian areas in lowlands support
many in-transit migrants as well as breeding Thick-billed Kingbirds,
Western Yellow-billed Cuckoos, and Southwestern Willow Flycatcher. Most
uplands in the United States are publicly owned, but lower-elevation
grasslands and riparian habitat are subject to development and conversion.
The whole region is an important corridor for migration of many species
in the west. Significant wetland habitats, such as Santiaguillo Lagoon
in Durango, Mexico, provide wintering habitat for large numbers of aquatic
birds, highlighted by Northern Pintails and American White Pelicans.
