Español Distribution, Abundance, and Reproductive Status of the Mexican Duck on the Sonoran and Sinaloan Coasts
Project Description The increase in agricultural development in Sinaloa and Sonora in recent decades has caused important changes in habitats where the primary vegetation was originally lowland forest. The hydro-agricultural infrastructure, such as wells, dikes, and drains has supported the emergence of new niches that bird species are taking advantage of in both states. Despite

Masked Bobwhite Monitoring in Known and Potential Habitat in Sonora, Mexico
Project Description Masked bobwhite (Colinus virginianus ridgewayi) is one of the most endangered birds in North America. With fewer than 100 birds estimated in the wild on Buenos Aires National Wildlife Refuge and a suspected population of 300 birds in Mexico, this species is at its lowest numbers in decades. Prolonged drought conditions accompanied by continued

Montane forest birds in the Santa Catalina Mountains: monitoring population trends and reproductive success and examining potential limiting factors for breeding populations
Project Description The goal of this study is to further our understanding of the population status, reproductive success, habitat needs, and potential limiting factors for breeding populations of montane forest birds in the Santa Catalina Mountains of southeastern Arizona. We will assess population status by conducting breeding bird surveys on four study plots. We will

Distribution and abundance of birds of conservation interest and identification of important bird areas in Sonora, Mexico
Project Description We propose to present information on distribution, abundance, and habitat of breeding birds throughout Sonora, Mexico, and identify areas of conservation interest across a range of vegetation communities. To generate estimates of value of significance, we will devise a ranking system based on species richness, presence of species that are locally or regionally
