Ptychoramphus aleuticus. As usual, eggs and young in various stages. Adults on eggs, young always alone. One adult bit me quite severely; usually they make no defense. Oceanodroma homochroa. Got 12 to-day. With two one or two exceptions all with eggs. Nests as usual in rock piles or under with soil and bits of stone at end & burrow with no nest structure. Found one under railroad tie; saw tail and wings sticking out. Another had a nest lined with short grass stems, but evidently they were there originally or had worked in through a crevice; it is not likely that the bird carried them there. Nearly all would eject orange-colored oil when caught. Can throw it a foot or more. Is it done in defense or merely to appease the enemy? All of the eggs but one were fresh or slightly incubated; in that one incubation was quite advanced. (June 26, 1911? Saw one female Carpodacus mexicanus June 27, 1911. in garden at house.) S. E. Strallond., Calif. Wind NW; 35 miles per hr. I'm the forenoon worked around the main hill at the east end. Saw two or three Pseudiria columba and Lunda cirrhata nests with eggs but no young yet. Saw these two species and Urid troile and Ptychoramphus aleuticus as usual. Larus occidentalis common. I worked in the cove near the north landing place for petrels. Took twenty of Oceanodroma homochroa from stone walls and rock piles.
