Abstract Video camera technology is an increasingly common
tool in the study of burrow-dwelling animals. A camera used to observe the
inhabitants of narrow burrows on Takapourewa (Cook Strait, New Zealand) is
described. Population densities (animals per m2) of up to 1.1 for
fairy prions (Pachyptila turtur), 0.06 for sooty shearwaters
(Puffinus griseus), and 0.15 for tuatara (Sphenodon punctatus)
were estimated in four different habitats. These data are similar to other
estimates collected in more labour intensive studies on the island, and provide
baseline information for future conservation work on Takapourewa.
