Newell's shearwater donkey-like braying call around the breeding areas. Townsend's shearwater ("P. auricularis") is very similar but has dark undertail-coverts, a shorter tail and a less sharp boundary between the black and white on the face. It was described as a new species "Puffinus newelli" in 1900 by the American ornithologist Henry Wetherbee Henshaw using specimens obtained by Brother Matthias Newell from residents of Maui.

Later, Townsends's shearwater was raised back to species status with Newell's shearwater as a subspecies of it. This
Giannutri in the northern part which become "garrigue" in the southern. Plants as "arbutus", "Myrtus", "pistacia lentiscus", mock privet, Mediterranean buckthorn, "juniperus phoenicea" and "limonium sommierianum" knew only on Isola del Giglio and Montecristo, grow up on the island.
