Muthagrot (cont) At 4:50 the red & left the nest looking wet and bedraggled and with a feather stuck to his bill which he removed with foot after several attempts to snap it off on the ground. Female F was calling from ridge tops about 25 yards from nest. The red &, however, arrived slightly downhill diagonally, walked 20 yards or so, then stopped to preen for about 3 or 4 minutes. Female F did not see her although only 15 yards away. The red & did not seem disturbed by the calling F, but definitely did not head towards her. After preening, the & continued diagonally downhill and then was seen by the F, who started after her. When they met, the & fluffed + postured and the F darted away about 5 yards. One or both gave twittery-squeaky sounds that could hear 70 or 80 yards away. After her dart, the F returned, but the & ran off, initiating a chase that lasted 40 or 50 yards downhill. Not a well-small food-down chase like the territory disputes, but more of it at a fast run with weavings + sharp turns. The & finally gave her (and me) the slip.

At 5:35 she seemed to see or hear something uphill and started at a run after it. Went swiftly about 50 yards up the gully beyond the nest, making me as another occasion of a long bare rock slide. When she had gone up about 50 yards she looked (puzzled), looked
