142 nesting sites in five study areas totalling 7 800 km2 around Marlborough, Kaikoura, North Canterbury, Cass and Fox Glacier were used to measure local densities of New Zealand falcons. Adult falcons are considered to be sedentary. The spacing of nesting territories in each study area is illustrated. Territories in Marlborough and North Canterbury averaged 3.80 and 3.95 km apart. Six territories near Fox Glacier averaged 13.7 km apart but some pairs had probably been overlooked. Falcon pairs in open country probably had home ranges of about 15.0 km2, and those in forest areas ranges of less than 189.0 km2.
