The little-known Heinroth's shearwater ("P. heinrothi") is sometimes considered a subspecies of either Audubon's or the little shearwater. Though it is likely to be another member of that close-knit group, its actual relationships remain uncertain due to lack of specimens. Audubon's shearwater itself has around 10 subspecies. Several have at one time or another been suggested to constitute separate species. For example, the Galápagos Islands population has turned out to be a very distinct species, the Galápagos shearwater ("P.
Persian shearwater Persian shearwater The Persian shearwater ("Puffinus persicus") is a seabird in the family Procellariidae formerly lumped in with Audubon's shearwater ("Puffinus lherminieri"). There are two listed subspecies of the Persian shearwater: After breeding, the northern subspecies ranges from the southern Red Sea, the Gulf of Aden and the Somali coast across the south of the Arabian Peninsula to the Gulf of Oman, Pakistan and western India. The southern subspecies stays in the area around the Comoros and the Tanzanian and northern Mozambican coast. The nominate subspecies is thought to number in the thousands of pairs on the Khuriya Muriya Islands
