    • Trend estimates of common raven populations in the United States and Canada, 1966 - 2018

    Metadata Updated: October 29, 2025

    These data identify the mean population growth rate and ratio change in abundance of common raven (Corvus corax; ravens) populations from 1966 through 2018, delineated by ecoregions defined by the U.S. Environmental Protection Agency. This enables researchers and land managers to identify regions which may be more heavily affected by growing raven populations.
