White-necked/Vanuatu Petrel ID

["Greg & Val Clancy" <>]

Hi Tom,

I will have a look at your photos but am not confident that I could tell 
them apart.

The Vanuatu Petrel was as a new species, and not just a subspecies of the 
White-necked, in a paper in Emu in 2001.  The reference is:
Imber, M. J. and Tennyson, A. J. D. (2001).  A new petrel species 
(Procellariidae) from the south-west Pacific.  Emu 101: 123-127.
It is an interesting read!

Regards

Greg Clancy
