Field Notes Doug Bell
June 12, 1988
Left Berkeley at 18:00, going north on HWY 101. Exactly 96.4 miles later I stopped at Squaw Rock to look for the peregrines. 20:00 - after watching the rock for only a few minutes, the tiercel came into view out of the NW. He arced across the rock face in long swoops, then landed on a small ~~~~~ rock to the left and below of the nesting ledge. It looked like he was holding a chunk of small bird in his r.t. foot, but the next minute he wasn't holding it anymore. I didn't see him eat it, so I might have just missed seeing him cache it in the corner. The tiercel is on a well-protected and overhanging rock that is walled on 2 sides dry cliff face. He preened his shoulder a bit, then looked around at some of the swallows flying by. Seems to be quite related.
I hiked up the opposite slope a ways to get a better view of the nest ledge. It looks good for all the ~~experiment~~ ~ white-wash. Do they have young? The falcon flew into view and landed on a ledge to the right and below the nest ledge. No sound of begging young. & preening. The male's back is to me - he looks very dark, especially the head. Malar stripe present as ~~a~~ "cap". His cere & feet are deep yellow - breast appears very "clean". The female as looks dark, but her soft parts are duller yellow. Watched these two sitting in their respective rocks until 21:00. No other activity seen. It is encouraging that they are roosting so close the nest ledge. Talked to Marty Kinners (BCM) over
