I heard another flight + screeching from the second ridge beyond nest. I located three females, all within a few yards of each other. One which I took to be a female, was acting most belligerent. She climbed onto a rock and started screaming at the other two birds faced. The red bird at this point took a short flight with screeching across the gulley to his feeding grounds. Soon lost his try trying to watch the birds on the second ridge, also lost those birds. A little while later I heard sustained screeching from the big lode across the main gulley. Looking over, I located three ternors. One was a male fostering actively to a female, who started away at his advances. The other bird I didn't get any dope on. I didn't see a red on any of the, although they were fairly far away & I wouldn't be positive one wasn't red. I watched the ? (I think) wander away by herself for 10 minutes or so. Bird returned to nest at 9:35, screeched up gulley. March 15 Went to nest #1 at 8 A.M. There was flying down hill to left & bird as I approached. I thought the bird was off the nest. Looked
