An analysis of a recreational hunter's red deer tallies in the Tararua Ranges, North Island, New Zealand
We examined the jaw size, age and sex distribution of 324 red deer constituting a comprehensive record of all recreational hunting kills made by a single hunter of the Tararua ranges of North Island New Zealand over a period 20 years (1976-1996). The proportion of stags shot at times other than the rut (March—April) was not significantly different to that in a sample of deer obtained by commercial helicopter hunting and did not change significantly after the first three years of hunting regardless of any effect of helicopter hunting.
Sex ratio of North Island kaka (Nestor meridionalis septentrionalis), Waihaha Ecological Area, Pureora Forest Park
The sex ratio of the kaka population inhabiting the Waihaha Ecological Area, Pureora Forest Park was estimated between late October 1994 and January 1995. The observed sex ratio estimate was three males to one female compared to a capture rate (using mist nets) of six to one in the same area between January and June 1994. Females appeared to be less susceptible to capture than males. The skewed sex ratio toward male kaka was significant and suggests that female kaka suffer higher mortality (probably due to predation at the nest) than males.
