Bill Arvey Journal Pt. Baker, beneath Golden Gate Bridge Marin Co., Calif. (3) Nov. 11, 1966 although of course one would have to know what the sequence is and so on before you could judge. There are several cormorants on the rock; I'll try to get a relative number of Brandts to Pelagics. I'm watching a Brandts Cormorant that flew up on top of one of the higher parts of the rock where there aren't any others and I'm watching his movements. He's picked up a whole beakful of grasses and lichen as if gathering nest material. Very strange; I wonder what he's going to do with it. He's still picking it up in his beak. Maybe this is one of the ones that was displaying down there, and if so he might bring it back. One of the pairs that I mentioned as being Pelagic that were displaying on the rock I now think are Brandts. I notice this fellow when he wants to go just a short distance on the rock, he'll take alternating short steps, but when he wants to go a little further and higher, he makes a hop thrusting with both legs. First he extended his neck, then he made a hop with both legs and flapped his wing once. Then he hopped a foot or 2. Off he flew, flying back in, gliding. He went around to the other side. I'll go around to see how many cormorants are on the other side of the rock. 7:30: just returned from the other side of the
