In January 2001 burrow occupancy for two species of Shearwater
Puffinus carneipes and
Puffinus pacificus
was ascertained by using a burrowscope to inspect burrow contents at various sites on Lord Howe Island. Burrow
occupancy (and burrow lengths) for
Puffinus carneipes and
Puffinus pacificus averaged 60 per cent (1.4 m) and
57 per cent (0.8 m) respectively. Neither burrow density nor the amounts of litter covering burrow entrances were
good indicators of burrow occupancy.
