conditions:-Overcast; windy; moderate temperature. I saw a humming bird in the back yard when I got up; it was engaged in sticking its long bill into the flowers of a tree mallow (davatera assurgentiflora). I think it was Calypte anna. In the backyard was also a pair of Aphelocoma californica engaged in picking up food in a chrysanthemum bed. Regarding this species, I heard recently from a friend that they get into his hen-house during the day and suck the eggs. Of course I saw a great many Passer domesticus in the yard and as I went up the street. Females are more abundant than males. At the roundhouse I saw a small flock of young Larus occidentalis on a narrow strip of beach. On the bay I saw nodarua heermanni. I saw a couple of Uria troile on the water off Goat Island. San Francisco, bal. to Alameda Mole, bal. 5:15 P.M. to 5:35 P.M. conditions: Overcast; windy; slightly cold. I saw considerable numbers of Larus occidentalis flying and also a good many on a strip of sand north of Oakland creek. I saw two Larus heermanni both in flight. This species has decreased very suddenly in numbers. Off Goat Island was one Uria troile on the water. JUL - 7 1904 Alameda, bal. to San Francisco, bal. 7:00 A. M. to 8:00 A.
