Field Notes Doug Bell April 9, 1989 falcon [illegible] land yesterday. The next ledge from last year, the long horizontal cleft across the face of Squaw Rock, appeared to have been reduced in size - possibly due to rock slides. There are now two shelf areas, both with rocks piled up on their outer ledges, where I think there had been one long, continuous shelf. The rock piles appear to have been man-made (Monty Kivens' Group - ledge improvements), but they sure look fragile. Not too much experiment on the ledges proper. No sign of the falcons. The sun was setting, I kept hiking up higher, staying just in the shaded lee of the rock so I could still focus on it. Clearly saw the raven incubating in her nest. Lots of swallows up way high (500') and to the north of the rock. Air still, loaded with insects, warm. After long searching, I saw a falcon pop up from behind the rock pile on the right-hand ledge. It looked out over the area (possibly at me), then walked down out of sight behind the rocks after only a minute or so. That is, I guess, where the falcons are incubating.
