Ptychomorphus alenticus. Burrows everywhere. Found one with nest in crevice where bird could be seen from outside. [In front of the keepers' houses there are a great many dead which have struck the telephone wires at night.] Larus occidentalis. By thousands on crest and northwest parts and on Maintop, where young were seen at the very top. On the northwest part they hovered over me by thousands while I was passing through a low level place where their young were abundant. Found several nests with two and three incubated eggs. The minute cormorants or murres leave their nests the rascally gulls are down breaking and eating eggs. The gulls keep up a continual calling, and when one gets in their nesting quarters they also make an angry clucking note, very often swooping at one at the same time. Saw one or two adults with banded tails, but no brown young. Phalacrocorax penicillatus. A very large colony on northeast side, nests about two feet apart. One nest with two similar eggs and one about 1/3 natural size. Another colony on northwest corner near Arch Rock, and still another colony on southwest corner. No young yet. Adults losing head filaments. Four eggs laid. Phalacrocorax pelagicus. Here and there on cliffs high up. Fair reports eggs in some nests. No large colonies. Phalacrocorax auritus. Colony of perhaps a hundred near summit of Maintop. With young, some well feathered, others in black down. One egg seen, perhaps added. Saw gull pursue adult Dolichotis obsoletus. Common on east and west ends. Two or three sparrows[c]?
