The Kookaburra is a very large kingfisher with a heavy black and yellow bill, a pale head and underparts, a brownish back and a rufous, black barred tail. The call is a raucous laughing cackle ‘koo-koo-koo-kooah, ha-ha’. The diet is mainly earthworms, snails, insects, freshwater crayfish, frogs, lizards, rats, mice and small birds. Breeding is between November and February. The nest is in a tunnel bored in a rotten tree trunk, or in a cavity in a Pohutukawa. The clutch of 2 – 4 white eggs is incubated for about 23 days and the chicks fledge between 33 – 39 days. They may be fed for several weeks after. In recent years there have been 2 – 3 sightings on Tiri.
