The Foods, Foraging Behavior and Habitat Use of North Island Kokako in Puketi State Forest, Northland
The foraging behaviour, diet and habitat use of North Island kokako (Callaeas cinerea wilsoni) were studied in Puketi State Forest from October 1981 to August 1982. Kokako fed mainly from branches and twigs of canopy and upper-understorey plants. Although 68 different foods were eaten, only eight contributed more than 5% to the observed diet in any season. The diet consisted of fruit (44%), unknown foods (18%), leaves (15%), epiphytes (11%), invertebrates (8%), buds (2%), flowers (l%) and nectar (1%). The use of these food- types varied seasonally.
