Related Species

described as Aestrelata cahow Nichols and Mowbray 1916; type locality southeastern side of Castle Island, Bermuda. Holotype a live bird found at Gurnet Rock during a strong storm 22 February 1906 that later died at the Bermuda Aquarium (now American Museum of Natural History [AMNH] 789769).

Bermuda Petrel is most closely related to other gadfly petrels that nest on islands of the Caribbean (currently, Black-capped Petrel Pterodroma hasitata) and the eastern North Atlantic, Fea's Petrel (Pterodroma feae), "Desertas Petrel" (Pterodroma feae deserta), and Zino's Petrel (Pterodroma madeira) (Jesus et al. 2009). The most comprehensive analysis of this group of gadfly petrels, by Jesus et al. (2009), used morphological characters and mitrochondrial DNA sequences and confirmed the monophyly of this group. Within this assemblage, hasitata is basal to a clade that includes cahow, deserta, and feae.
