38. × In the forenoon I spent some time looking for petrels on the east side of the island near the wireless Telegraph station. I found three Oceano-droma homochroa in rock piles and under rocks. There was no semblance of a nest in any case, the egg being laid in a depression in the soil and bits of stone. I found a couple of Pseuduria columba eggs in a cranny in the rocks up on a hillside. × In the evening I searched a rock pile right in front of the house and found three more Oceano-droma homochroa, two of them with eggs. In the afternoon I worked about the west end. × No Petrels found although looked for. Uria troile. By thousands everywhere. An outlying islet on the north side was black with them as was also the north side of Manitop in certain places. No eggs hatched yet. Many were nesting under large rocks well back from shore. When disturbed they never resisted but huddled to- gather, making occasionally hoarse notes of alarm and distress. Pseuduria columba. Quite a few along shores, where they sit about on the rocks apparently resting. No nests were found on the west end. Lunda cirrhata. Very common about the cliffs and ledges. Flight resembles that of a parrot, notably Conurus bolo-chlorus. Found several nests in crannies and holes under rocks. No young found. Egg laid in depression in soil. Egg with chick nearly ready to hatch.
