Puffinus auricularis (Townsend's Shearwater; Newell's Townsend's Shearwater; Manx)

Synonyms: Puffinus auricularis auricularis
Language: French; Spanish

Wikipedia Abstract

The Townsend's shearwater, Puffinus auricularis, is a rare seabird of the tropics from the family Procellariidae. Its relationships are unresolved. Its closest relatives are probably, but not certainly, the Hawaiian shearwater (Puffinus newelli) and possibly the Manx shearwater (Puffinus puffinus) (Austin, 1996; Austin et al., 2004). It formerly contained the former as a subspecies and was long considered a subspecies of the latter. The relationship of the Rapa shearwater, P. myrtae in regard to these species are also in need of research; this taxon was until recently placed in P. assimilis (Austin et al., 2004), but now raised to full species status by the IOC and the NACC of the AOU.
