The region's avifauna is exceptionally diverse: over 500 birds species have been recorded in the region, and 17 species are unique to it (endemic)--specialties such as the Yellow-footed Gull, Xantus' Hummingbird, LeConte's Thrasher, and Rufous-winged Sparrow. For another 20 species, over 50% of their entire world population resides in the region.
While humans have been a presence for over 10,000 years, in recent times "snowbirds" and city folks have flocked to the desert in ever-increasing numbers, drawn by the sun, open space, and hard soils to retirement living, military exercises, and off-road driving. It is no wonder the forces of conservation have begun to concentrate on the fragile deserts of the Southwest.Early in 1999, when numerous conservation planning efforts were in full swing and converging on North American hotspots of biodiversity, individuals from The Nature Conservancy, the Arizona Game and Fish Department, and the U.S. Fish and Wildlife Service convened an international meeting to discuss the conservation needs of the unique Sonoran Desert ecosystem. From this meeting fledged a new and different Joint Venture: a venture dedicated to international cooperation, between the U.S. and Mexico, and to a then novel "all bird" approach. Since its inception this JV has embraced the "all bird" concept, in recognition of the Sonoran Desert's many unique habitats and upland species.

The Sonoran Joint Venture has since expanded its boundary and influence: it now includes the Mojave Desert to the north, the state of Sinaloa (Mexico) to the south, and the unique coastal scrub of Baja and Southern California to the west. The JV continues its cutting-edge approach with an innovative Awards Program. Recognizing the need for baseline information and education in the desert, the Awards Program has supported an amazing array of projects--north, south, and cross-border.
Last year the Sonoran JV supported training workshops in Mexico, interns and graduate students doing important research, standardized monitoring projects of common and priority species, and Mexican participation in a fall 2003 workshop in Yuma, Arizona. Led by PRBO and coordinated by Terrestrial Ecology Biologist Chris McCreedy, the workshop began work on a Desert Bird Conservation Plan and produced many new partnerships, bringing researchers, government biologists, land managers, and Audubon Society volunteers together for the first time in the name of desert birds--a dynamic convergence for conservation.
