roundhouse-there were a good many swale Tringa and a few gulls this morning. The same species were observed this evening but in greater numbers. On the bay this evening the following species were observed:- Larus glaucussens. As usual: Several stood on the piles as the boat left the slips allowing it to pass within half a dozen feet of them. All were immature. Occasionally one standing peacefully on a pile is driven from it by another cow at him and uttering a sharp squawk just as it is about to alight, apparently on the other's back. Larus occidentalis. An adult seen flying about in front of the slips. Larus Californicus. Abundant as usual. Several immature once seen. It is common thing each evening to see quite a few of this species on the water all the way across, both singly and in flocks.
