In 2014, the Rocky Mountain Bird Observatory (RMBO), in cooperation with its partner, the National Park Service, completed its tenth year of a habitat-based landbird monitoring program in the Northern Colorado Plateau Inventory and Monitoring Network. This program is designed to provide rigorous population trend data for most diurnal, regularly occurring breeding landbird species throughout the Northern Colorado Plateau Network. This population information is useful for land managers and supports the National Park Service’s goal of long-term monitoring of biological indicators for network parks. In 2014, RMBO biologists surveyed 45 survey locations in 11 national park units. Fifteen transects were located in each of the three habitats of interest: low-elevation riparian, pinyon-juniper, and sage shrubland. In 2014, each location was surveyed once (in previous years, each location was surveyed twice). The decrease in sampling effort resulted in the detection of fewer species and individuals when compared to past years. We do not expect the decrease in effort to significantly impact density estimates; however, a decrease in number of detections for a species in a given year due to decreased effort may impact the percent coefficient of variation (%CV) for that species. In addition to the habitat-based surveys, we conducted four point counts and four area searches at Pipe Spring National Monument, using a modified monitoring design.
