General characteristics 

This highland EBA extends from the Chisos mountains of southern Texas in USA, south-eastwards along the north-east edge of the arid central-northern Mexican plateau in Coahuila state to the northern part of the Sierra Madre Oriental in Nuevo Le

Restricted-range species 

The EBAs two restricted-range species overlap in the northern part of the Sierra Madre Oriental, which encompasses the entire range of Rhynchopsitta terrisi. The breeding range of Vermivora crissalis extends the EBA further north. Lanning et al. (1990) showed that V. crissalis was present in most areas of open pine oak forest where the average height of the trees reached 8

Threats and conservation 

The mixed-conifer forests of this EBA are being destroyed by fire, logging and clearance for agriculture. This habitat destruction is the reason for Rhynchopsitta terrisi, which has a relatively circumscribed range, being judged to be threatened. The largest single observation since 1978, and perhaps ever, was made in October 1994 when 1,480 birds were seen (E. Enkerlin in litt. 1995). A significant portion of the southern half of this EBA, and indeed the range of R. terrisi, is covered by the Cumbres de Monterrey National Park (2,465
