Bannerman's Shearwater (1 Viewer)

'Puffinus lherminieri bannermani is a small black-and-white shearwater, which is endemic to the Ogasawara Islands, Japan. The taxonomic position of this shearwater is contentious. It is treated as a subspecies of Audubon's Shearwater P. lherminieri'

Audubon's itself was split from Little Shearwater Puffinus assimilis, how far can this be taken!

IOC lists at least 8 species (maybe up to 11?) that used to be lumped within Little, including Bannerman's.

But that treatment is quite old now, I believe based on

Austin, Jeremy J.; Bretagnolle, Vincent; Pasquet, Eric (2004). "A global molecular phylogeny of the small Puffinus shearwaters and implications for systematics of the Little-Audubon's Shearwater complex". Auk. 121 (3): 847–864

and detailed in the Onley and Schofield book from 2007.

These isolated island populations of widespread tubenoses are going to keep throwing up splits i think

Are they identifiable in the field as in, distinct from each other or will people tick them on range?

I guess that depends. Some look more different than others. Probably no worse than the Manx complex (yelkouan, fluttering, hutton’s etc)

I could not find this paper referenced anywhere through searches:
Kazuto KAWAKAMI1,#, Masaki EDA2, Hiroe IZUMI2, Kazuo HORIKOSHI3 and Hajime SUZUKI3
Phylogenetic position of endangered Puffinus lherminieri bannermani, 11Ornithol Sci 17: 11 – 18 (2018)

This is quoted by Clements as reason to split this taxon as a species. They show the species to be more closely related to the trio of Townsend's Shearwater, Newell's Shearwater, and Rapa Shearwater.

Sorry I did not express that very clearly. I did find the paper but I did not find a mention of it in the taxonomy forum here.
