英文摘要	In 2012, landbirds were surveyed within all 11 of the Sonoran Desert Network (SODN) parks. Sample points were located along a transect (in most cases) or a grid. A total of 46 transects or grids was surveyed in 2012. Survey efforts were focused on the breeding season, when increased territorial behavior by songbirds results in higher detection rates and greater sampling efficiency. The window of primary breeding and, therefore, sampling was from April into June, with adjustments made for individual park visits based on latitude and elevation. We used point-transect surveys to estimate and monitor landbird population parameters. Surveys were conducted twice for each transect or grid to facilitate estimates of occupancy, which rely on an encounter-history matrix derived from repeated visits, rather than a detection function to account for detectability.
