S.B.Boorin 1968 Oceanodroma sp. White-rumped Storm Petrel (?) 10 Oct.- Saw first bird today, almost certainly a Leach's. 07°45'N; 166°38'W — 07°36'N; 165°48'W 11 Oct. SAW ONE BIRD TODAY; ALMOST CERTAINLY a Leach's. 12 Oct. 03°57'N; 169°10'W — 01°58'N; 170°37'W Numbers up to 4 today. Three more noticed in a group and shortly, there gets a single. All almost certainly in Leach's category. BOORUM & PEASE "NOTE" S.B.Boorin 1968 White-rumped Storm Petrel (?) McLean Island 14 Oct. Noted two birds settling between 2030 and 2100. One had a bare breast patch; other not caught. Neither raise near nest sites, sort of settling short in, open along W. side. 15 Oct. Sighted one dead fully-feathered young along swell wall midway of the island on West side. Began an evening observation at 1820 at well on W. side. 1823: first adult bird flying over rocky area between two m. in large section of rock walls. 1824: second bird was in air 1827: 3rd bird was settled nearby area. 1828: 3rd bird settles coming in and alighting. Couldn't find any one of the three— 1933: two birds noted flying by wall along Serenian along lagoon. For hour or so before I would sit out until 1945. Other keep looking in on spot, but always flying off and circling some more before returning. Finally lost them — 1845 now too dark to see. 17 Oct. Birds have three marked nests; two with chicks and one with ad. settling in empty nest. Accidentally broke a recently incubated egg last night under a clump of Corallina. No parent attending at 2005 (1600). The birds call from the nest cavity in a soft grunted "grrrr, grrrr, grrrr". Thus for most birds, these were good about such calls. Perhaps in July '68 when so many were found under clumps of Corallina that there was a population peak and birds were perhaps forced out at night.
