Taxonomy
The Ashy Storm Petrel was first described by American ornithologist Elliott Coues in 1864. Both its common and scientific name, homochroa, "uniformly colored", from Ancient Greek (h)omoia (όμοια), "alike" + "chroma" (χρώμα) "color", come from its coloration. One authority has suggested naming it Coues's Storm Petrel after its describer.
