Townsend's shearwater Townsend's shearwater 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
Yelkouan shearwater Yelkouan shearwater The yelkouan shearwater, Levantine shearwater or Mediterranean shearwater ("Puffinus yelkouan") is a medium-sized shearwater in the seabird family Procellariidae. Yelkouan shearwaters are 30–38 cm long, with a 76–89 cm wingspan. It has the typically "shearing" flight of the genus, dipping from side to side on stiff wings with few wingbeats, the wingtips almost touching the water. This bird looks like a flying cross, with its wing held at right angles to the body, and it changes from very dark brown to white as the dark upperparts and paler undersides are alternately exposed as it travels low over the
