Range Description

Hydrobates macrodactylusmay persist on Guadalupe, Mexico, 280 km west of Baja California. It was abundant in 1906, but the last record of a breeding bird was in 1912. Searches in 1922, 1925 and the early 1970s failed to find the species. However, there has been no thorough survey in the appropriate season since 1906. Relatively recent reports of storm-petrels calling at night and the apparent persistence of breeding Leach's Storm-petrel H. leucorhouson the island raises some hope that it may survive, although this is unlikely unless it is able to nest in rock crevices in areas inaccessible to cats (Keitt et al. 2009).
