In 1991, PIF began developing a formal species assessment process that could provide consistent, scientific evaluations of conservation status across all bird species in North America, and identify areas most important to the conservation of each species. This process applies quantitative rule sets to complex biological data on the population size, distribution, population trend, threats, and regional abundance of individual bird species to generate simple numerical scores that rank each species in terms of its biological vulnerability and regional status. The process results in global and regional conservation assessments of each bird species that, among other uses, can be used to objectively assign regional and continental conservation priorities among birds. The information used and generated by this process is housed in the PIF species assessment database which is maintained by the Rocky Mountain Bird Observatory. The database is currently undergoing revision. Scores should be cited as “Partners in Flight Species Assessment Database. 2005. Rocky Mountain Bird Observatory www.rmbo.org/pif/pifdb.html”.
