General characteristics 

Several mountain ranges in southern Oaxaca and southern Guerrero states of Mexico together form the Sierra Madre del Sur. The isolated Sierra de Miahuatl

Restricted-range species 

The restricted-range birds are found mainly in humid montane forest consisting of many evergreen tree species, especially oaks, with variable amounts of pine at higher altitudes. Because the altitudinal ranges of particular forest types vary according to the local topography and climate, the restricted-range species appear to show quite wide altitudinal preferences.

Lophornis brachylopha is still known from only a single 25-km stretch of the Atoyac-Para

Threats and conservation 

Many of the forests of these mountains are being cleared for large-scale agricultural expansion or for timber, and it has been suggested that all are in danger of complete destruction (Navarro 1992). The lower montane forest is being cleared for corn, fruit (notably citrus fruits in the Sierra de Miahuatl
