Kokako characteristically bound and run among branches, interspersed with glides on short, rounded wings.
They are usually located by listening for song and calls. Voice: rich, sonorous, sustained, organ-like notes are sung by both male and female North Island kokako, frequently as duet, and typically from a high perch.
new populations are established with individuals from two different source populations, totalling 40 founders.
Threats and conservation Predation at nests by ship rats and possums is the primary cause of current declines of North Island kokako.
Kokako populations are easily isolated by forest fragmentation.
The tall forests they inhabit and their alert and skulking behaviour mean that most kokako are detected by their song and other vocalisation, frequently delivered from the tops of tall trees at dawn.
The largest populations, with more than 100 pairs each, are in Pureora Forest, Hauturu (Little Barrier Island ), Te Urewera, Mapara (Waikato), Rotoehu (near Rotorua) and Hunua Ranges.
Other large populations ( 50 prs) are at Mataraua/Waima (Northland), and Kaharoa-Onaia near Rotorua, and there are 14 other smaller populations.
Breeding North Island kokako typically raise one brood during November-February, after which they moult.
