Second record of Bryan’s Shearwater Puffinus bryani from Midway Atoll, with notes on habitat selection, vocalizations and at-sea distribution. Marine Ornithology 42: 5–8. Little is known about the conservation requirements of Bryan’s Shearwater Puffinus bryani, first described in 2011 based on a specimen collected in February 1963 near an area containing concrete rubble at Midway Atoll. Here we document a second Bryan’s Shearwater observed on Midway during the winters of 1990/91 and 1991/92. It was vocalizing from a 0.5–0.7 m crevice within an accumulation of artificial concrete and coral rubble. Recent winter specimens of Bryan’s Shearwaters from the Bonin (Ogasawara) Islands, Japan, were also collected in areas with rocky crevices, possibly burrows they co-utilize with summer-breeding Bulwer’s Petrels Bulweria bulwerii.
