Larus philadelphia. I saw three or four gulls at a distance which acted like this species. Buteo borealis. Yesterday a little after noon I saw a large hawk, apparently this species, around Nob Hill, San Francisco, quite high in the air. It was a very clear day. September 18, 1907. Alameda to and from San Francisco, cal. Conditions: - Very warm; clear; W W wind in the af- ternoon. The tide was so high this morning when I went to the city that there were no gulls on the beach near the roundhouse. A short ways off shore, however, I noted a flock of about thirty bunched together on the water. I rode inside the steamer both ways, but an occasional Larus californicus and one Larus heermannii were noted. For the past few evenings I have noted a great many Euphagus cyanocephalus in the eucalyptus trees along the shore near 5th St. Station.
