The current RPI analyses (2009-2019) include data from 76 fall and spring count sites and include 1009 trend estimates for 28 diurnal raptor species. We present results for all of North America, and for four regions (West, Central, East, and Gulf). These analyses represent the most current assessment of the status of migratory raptors in North America. This research is possible because of data and time contributions of the sites, including their coordinators and counters, and the RPI partnering organizations. Results are viewable by: map and species combinations, by count site specific graphs for each species, and synthesized in short species conservation assessment reports.
