General characteristics 

This EBA includes a number of mountain ranges of eastern Mexico, principally within the Sierra Madre Oriental and the Sierra Madre de Oaxaca. The northern end of the EBA begins in the Sierra Madre Oriental from southern Tamaulipas and eastern San Luis Potos

Restricted-range species 

All of the restricted-range birds are forest species, with humid montane forest being a particularly important habitat, though there are some marked distributional differences between the species. Glaucidium sanchezi is currently known only from the forests of southern Tamaulipas and eastern San Luis Potos

Threats and conservation 

The majority of the forests of this EBA have already been lost or degraded, and today this destruction continues through logging, agricultural expansion, firewood-gathering, road and associated tourist developments, sheep-ranching and overgrazing, as well as intensive urbanization (Dinerstein et al. 1995).

This habitat destruction is the main reason for the threatened status of Dendrortyx barbatus and Cyanolyca nana. Several Key Areas for these birds have been identified by Wege and Long (1995), but they have not been recorded at most sites for more than 20 years, being known with certainty to occur in only a couple. Cerro San Felipe in the Sierra Aloapaneca is the only current site for C. nana, in spite of many bird surveys in parts of its former range (A. T. Peterson in litt. 1995). Coatepec in Veracruz (G
