Abstract

The spatial distribution of Wedge-tailed Shearwater burrow entrances on Rottnest Island, Western Australia, was investigated using the
single- and two-sector nearest neighbour methods ofpoint pattern analysis. Both analyses yielded similar results. Mean burrow density was
0.32 ±0.02 SE burrows m-2, burrow entrances were not distributed at random and entrances tended towards an even distribution. Evenness
ofdistribution was positively correlated with burrow density. Social and structural factors are likely to be important in determining burrow
entrance distribution by Wedge-tailed Shearwaters and there appears to be a density-dependent trade-off between social benefit (aggregated
burrow entrances at low densities) and colony stability (evenly distributed burrow entrances at high densities).
