Abstract
This paper describes the search-phase echolocation calls of lesser sho rt-tailed bats (Mystacina tuberculata) and long-tailed bats (Chalinolo bus tuberculatus). Calls were recorded from all three subspecies of sh ort-tailed bat and seven populations of long-tailed bat, three in Nort hland, two in the central North Island, and two in the lower South Isl and. The calls were recorded in the field and digitised, then three sp ectral components and one temporal component of the calls were measure d. Calls of the lesser short-tailed bat could be loosely classified in to subspecies by means of multivariate discriminant function analysis. Similarly, long-tailed bat calls showed regional variation, and discr iminant function analysis was able to fit calls to regional groups wit h a high rate of success. The significance of the results presented is discussed in terms of the conservation of New Zealand bats and the un ique ecology of the lesser short-tailed bat.
