4021; Æx galericulata & Aviary, Alameda, Cal.; Jan. 9, 1910; C.A.S. No. 16177. January 11, 1910. San Francisco, California. This morning when on Bush St. near Lough about eleven o'clock saw four Larus glaucescens (immature) flying in an easterly direction towards the bay. January 12, 1910. This morning I saw a flock of about thirty sandpipers in the light near the round house, Alameda, Cal. There were several flocks of ducks flying and large flocks on the water along the mole. Larus glaucescens is the predominant gull. This morning I saw a dozen or so on the piles close to the building on the south side of Alameda Pier. January 14, 1910. This morning there was a flock of about forty sandpipers on the beach near the roundhouse. On the water south of the mole there were several large flocks of ducks, all too distant to be identified. While standing in the back yard at 3256 Briggs Avenue this morning, I saw a pair of ducks flying over the eastern end of town, my attention being attracted to them by the whistling of their wings. They were flying high.
