An investtgat1on into the association between covered burrow entrances and the breeding status
of occupants of burrows was prompted when Wedge-tailed Shearwaters were seen covering the
entrances to their burrows. The results showed that neither covered nor cleared entrances should be
used as indicators for occupied breeding burrows. Burrows with covered entrances may contain
incubating birds, and those with cleared entrances may only be used at night by immature birds. The
incidence of burrows with covered entrances was related to habitat type which influenced the availability
of litter and debris.
