Harrison Pravder (Department of Biology, Washington University in St. Louis, USA) and colleagues have published in the Journal of the Hawai‘i Audubon Society 'Elepaio on the breeding phenology of the Wedge-tailed Shearwater Puffinus pacificus on the Hawaiian island of Oahu.
Although it has no abstract the full paper is available free-access on line. "The goal was to document the timing of egg laying and chick hatching, to obtain more up to date breeding phenology data, and to estimate the duration of incubation for the species at this breeding location."
