The long-term effects on this population will be serious. Disproporti...
متن کاملEnergetics of South Island Kaka (nestor Meridionalis Meridionalis) Feeding on the Larvae of Kanuka Longhorn Beetles (ochrocydus Huttoni)
Kaka (Nestor meridionalis meridionalis) studied in Big Bush State Forest spent 35% of their feeding time digging out Ochrocydus huttoni larvae from live mountain beech trunks (Nothofagus solandri var. cliffortioides). Larvae of O. huttoni had a high energy value compared to that of other insects. The assimilation efficiency for energy of two captive kaka was 91 j: 3% when fed a diet of O. hut/o...
