R. S. Crossin 1965 Christmas I. Shearwater (contd) bushes on the east side of the island. This bird was collected on 21 July. The flight of this species is distinctly different from the wedge-tails. The straight-held rounded wings differ markedly from wedgies. August 7 - Estimation still remains at 3,000 at least 30 burrows were found so far with large young. These dark young are as large or larger than the parents, but still down covered. August 10- A banded bird (544-38003) was found with another mated bird which was not caught. A number of birds were found on the north end along the beach under the large boulders, some large chicks were noted here. Bonin Island Petrel - Aug. 7 - About 20 birds sitting in grass or at burrow entrances. No indication of nesting. About 1 dozen dead individuals found - at least one of these freshly dead. Estimated population 50 - 100 birds on the nights of the 5 and 6 only a few individuals were seen. August 8 Birds are increasing each night. 10 Aug - At least 10 birds seen by each of the members of the party during the nights banding. A few pairs seen by burrows. " 11 Over 30 individuals seen by me during the nights banding. Comparable numbers seen by other members of the crew. Considerably more pairs are now being seen. Husted and I observed one individual digging a burrow in the grass cover on west side. A few others were noted digging by other people. Bulwer's Petrel - Laysan 18-21 July On the first night on the island I discovered a pair of adults at the burrow; one outside, the other within. A chick estimated to be no more than a few days old was found within the burrow about 12" deep under a large tuft of grass in mixed grass-Seaevola cover at W side of island. Occasionally I found a single bird sitting quietly in clearings in the Scaevola cover. In the evening birds often were seen flying back and forth over Scaevola apparently attempting to locate their nest site. I believe the birds are not adept at locating the nest sites and may make 30-40 passes before finally zoning in. As a bird flies over the area near the nest site it moves very slowly and hesitatingly and once past the immediate area appears to recognize unfamiliar ground and immediately speeds up, takes a new swing around and repeats the process. A pair of birds were collected from a burrow on the 21 July. One of these was banded. Estimated population = 2,000 birds. 7 August Estimated population at least 2,000 birds. Many singles or pairs sitting by burrows, but the burrows are invariably empty. A few chicks are found. These small, down covered. Red-tailed Tropicbird - Laysan 18-21 July Estimated population = 3,000 birds. The red-tails nest primarily, if not exclusively under Scaevola frutescens and generally only where
