one fresh egg. It was about 15 feet from the ground, and the hole about 15 inches deep. There was considerable wood on the ground which had been dug out by the birds, one of which left the nest as we approached the tree. A couple of feet below was another hole of the same depth from which a Megascops asid was extracted. Two incubated eggs were found on the soft bottom of dead wood, etc. Hedymeles melanocephala, Psaltriparus minimus, yanophyia amoena, and 3 or 4 distant hawks were seen in this region. Agelaius phoenicus was observed about a deep swamp east of Leona Heights. At low tide this morning at the foot of Briggs Avenue I observed one Numenius hudsonicus, hundreds of sandpipers, two distant Ardea herodias, and one Nycticorax nycticorax in flight. May 12, 1908. Alameda to and from San Francisco, cal. Immature Larus californicus are common on the bay and on the exposed sand near the roundhouse at low tide. Two or three days ago there were quite a number of terns (apparently Sterna forsteri) along the mole. Quite a few shore birds, both large and small are also to be seen.
