18 June 1964 Thur. Oahu – Mokauuia Island left can about 1830 + walked ¼ mile up beach to Kalanai Pt. All our gear was in a waterproof (almost) plastic bag. The island lies only about 400' offshore, + is easily waded to. A current from E to W. runs through the channel, waves were light. Military say this may be of importance. No birds were in the air when we arrived at island (1700). No shearwaters appeared over land before dark, and only 2 or 3 did before we left. Nests at N. end of island (Wedge-tailed Shearwaters) hard to find, a bird handled tended to readily abandon area. Near Oahu (S.W. end of island) there is fine soil, & the wedge-tail burrows long (2' - 4') burrows in this. They can be handled & stuffed back into burrow, + will not abandon the egg. Burrows are not dense, scattered over the island, many in open or under tree – most seemed on lee side of tree, rock, or bush. Birds Banded: 615-15626-32 (9 birds) Birds handled with bands: 544-45408 " - 45416 " - 45478 615-03961 " - 07703 " - 15-- Of 13 birds in hand, 6 were banded previously. We can use recapture data to estimate island population
