Establishing a Mexican Breeding Bird Survey Program

Pardieck KL, Berlanga HA, Downes CM, Peterjohn BG, Ziolkowski DJ, Collins B

The North American Breeding Bird Survey (BBS) forms the foundation of non-game, land bird

conservation in the U.S. and Canada, providing large-scale, long-term population data for > 400

species. Similar population trend data are not available for most Mexican breeding bird

species, severely limiting Mexico's bird conservation planning efforts. A three-year BBS pilot

project in northern Mexico indicated expansion of the survey into Mexico was technically

feasible with 26, 28 and 34 routes sampled in 1993, 1994 and 1995, respectively. A total of 218

species was detected, including 29 of continental importance in the Southwest Avifaunal Biome

(Rich et al. 2004). However resources were insufficient at the time to implement and sustain

an operational Mexican BBS program. The Mexican avian conservation community has grown

substantially in the last decade as has their need for better trend assessment of breeding bird

populations. Dunn et al. (2005) estimate that a Mexican BBS program could provide adequate

population trend estimates for > 80 species of northern Mexican birds. Thus Mexico's National

Commission for the Knowledge and Use of Biodiversity has partnered with the U.S. Geological

Survey and Canadian Wildlife Survey to implement a Mexican Breeding Bird Survey program by

2010.
