Falcon rusticolus 7 July - Colville R. the gyp's feet. They both started at each other many times, each circling away towards her own nest after an encounter. It was beautiful to watch. There was no question that the gyp was faster than the peregrine and forcibly dominated the situation, although the peregrine did not retreat. Once they moved to each other feet locked together in the stealthy fashion of fighting raptors, and they fell ca 60-70 feet through the air before breaking apart. The gyp was on top and apparently she held the peregrine. This about 30 min. They quieted down and each bird went back into her own area. This is the first chance I have had to see an encounter between these two species near a gyp nest, and the difference in behavior of the gyp at her own nest is striking. When really pressed there can be no doubt that the gyp is the superior bird. In this I must now capitulate to Stevens and Melton, both of whom lose their views on observation of trained birds.
