Genus
Until recently the shearwaters were devided in two genera Calonectris and Puffinus, but based on dna-analysis Penhallurick and Wink (2004) have proposed a splitting of the shearwaters into three genera: Calonectris for the large shearwaters of the Northern Atlantic, the Mediterranean and the waters around Japan, Ardenna for a group of large Southern Hemisphere breeders and Puffinus for the smaller shearwaters such as the Manx’ group, Audubon’s and Little Shearwaters. This new taxonomy is now widely accepted, but not by all and is stil subject of discussion.
Physical charateristics
Small, dark brown, rather fluttering shearwater. Often entirely sooty-brown except narrow, silvery underwing bar. Some have white bellies. Long, slender bill is notable. Plumage similar to Short-tailed Shearwater P. tenuirostris but it has short, stubby wings, weak flight and longer bill. Differs from Audubon’s Shearwater P. lherminieri in its browner plumage, dark body and less white on underwing

Range
Pacific Ocean : West. Puffinus heinrothi is known from the Bismarck Archipelago and the seas around Bougainville in Papua New Guinea and Kolombangara in the Solomon Islands
Habitat
The only observations of this species ashore, and a comparison with closely-related species, suggest that it breeds in high mountains. It is believed to be a relatively sedentary species and its total population may not be above a few hundred.

Conservation
This species is categorised as Vulnerable on the basis of an estimated very small population and breeding range. However there is very little data on this species and on threat processes operating at breeding colonies; were more information available this might lead to a reassessment.
Although it is likely to breed on high, inaccessible mountains, all these islands have introduced rats, cats and dogs. Rats have been seen to at least 900 m on Kolombangara and are a potential threat to this burrow-nesting species, although cats are perhaps a greater threat.
