Beck’s petrel, ''Pseudobulweria becki'', is a small species of shearwater. Its specific epithet commemorates American ornithologist Rollo Beck. It is believed to nest on small islands with tall mountains around Melanesia. Described in 1928, and long known from only two specimens, sightings and collections in the 2000s confirmed the birds still existed, but are considered critically endangered by the IUCN. ==Description== It is dark brown above and on the head and throat. It is dark underneath the wings with a fairly distinct white wingbar. The belly and breast are white. It flies over open oceans with straight wings that are slightly bent back at the tips.
