These raptors are noted to be increasing in population in North America based on our recent analysis.
Raptors on the Rise (green). We identify species with wide-spread increases (dark green) as those with migration TSI’s greater than or equal to 0.7 during any time period (10-yr, 20-yr, or both), and species with moderate increases (light-green) as those with migration TSI’s greater than or equal to 0.4.
Note: Species with trend data from less than five sites continent-wide, e.g. Prairie Falcon, were not categorized due to insufficient trend data relative to the species distribution.
