Abstract

We report the 1st use of a satellite transmitter to track the endemic New Zealand falcon (Falco novaeseelandiae). The movements of an adult female bush falcon in Kaingaroa Forest east of Lake Taupo, central North Island were monitored during a 3-year period from Feb 2002. The geolocations of the falcon were mapped and revealed that the falcon remained close to her nesting territory throughout the study. The home range included an area of c.200 km2. The falcon nested in pine compartments (0–3 years old) for 3 consecutive years; her nests averaged 5 km apart. After nightfall the falcon was located within the 95% isopleth of her home range, highlighting her sedentary nature. During the breeding season the falcon appeared to wander outside of her home range, with the furthest recorded distance from its centre being 137 km. Throughout the 3 years, observations suggest the falcon preferred to stay close to open areas, which may be related to the frequency of hunting opportunities.
