Raptors at Risk

Sharp-shinned Hawk Image by Dave Brandes

Raptors at Risk have been determined through evaluating both ten and twenty year migration count trends and determining the top 30% of the species exhibiting the highest percentage of declines over the last two decades.

Raptors at Risk (red and orange). The red research and conservation priority group was determined for those species that showed the highest proportion of declines during migration counts and Christmas Bird Count winter surveys. The orange research and conservation priority group was determined for the species which approached the highest proportion of declines during migration counts and Christmas Bird Count winter surveys for the 10 year trend results. The 20-year trend results also are consulted to understand continental patterns. Red-tailed Hawk and Cooper’s Hawk have generally declined on migration counts but have been shown to be increasing during wintering surveys in northern states. Red-tailed Hawks have been shown to be short-stopping or shifting their wintering range Although further research is needed, we suspect both species are changing their migration behavior, thus we are not including them as Raptors at Risk at this time.

Raptors on the Rise (green) show the lowest proportion of declines during both migration counts and Christmas Bird Count wintering surveys, with strong increases in the 10 or 20-year period.

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.
