Adult Gyrfalcon
December 24, 2011
Fort Pierre National Grassland

This adult gyrfalcon killed a prairie chicken as we watched from 1/2 mile away.
As we drove closer, a red-tailed hawk and a rough-legged hawk were both trying to take her kill.

Here she is voicing her rage at the other raptors.

It appeared that the red-tail won out, the gyr left and flew south toward Sheriff Dam.
