Biel Orway Journal Ft. Baker, beneath Golden Gate Bridge Marin Co., Calif: (4) Nov 11, 1966 rock; there are approximately 15-20 cormorants on the south or S.F. side of that rock that I can see, and I'm sure there are some on the corner that I can't see. So maybe upwards of 40 cormorants can roost here. Some of the Brandts are roosting on very narrow ledges, as opposed to the usual prefer- ence for wider ledge, and it seems possibly that there is some overlap here between preferences at least for roosting between the Pelagics and the Brandts. In the breeding season, of course, the one that prefers the flat, open area is the Brandts, whereas the narrow ledge nester is the Pelagic. In the last few minutes I've seen several of the cormorants fly out from the rock, wheel around about 1/4 mi. off, and come back in. I don't know exactly what this means; maybe it's a warm up or something. From where I sit in the car now, there are 21 cormorants in view on this east side or left side of the rock. 7:36(1/2): a 5-min. observation: In--4; Out--1 The tide is coming in now because those rocks are underwater now, so it's raised about a foot in the 1/2 hr. I've been here. Quite alot of pelican activity out today, not too many big scans of cormorants, but I've seen 2 or 3 flights of pelicans, about 10 birds in each. Very interesting now; it looks like the tide is starting to rush in through the Gate, and I can see the line where the backwash is meeting the in-wash, so to speak, and out there in this moving water are pelicans that are diving like crazy, fishing, hovering, floating on the water, getting up and diving. I've seen this many times now, and there are lots of them out there. Also seems to be an abnormal number of gulls, too, that are working this incoming water, so possibly the incoming tide is bringing lots of food into the Bay, and this is what they're following and feeding on. I still have to look up the tide tables to see what high tide at the Gate is, but I'd bet it won't be long from now and I'd predict within a 1/2 hr. we'll see alot of cormorant activity into the Bay. A couple of minutes ago I saw a cormorant leave the rock, (7:50) fly off to the east. Before he went
