Nest
In a hollow of a tree, in a chamber tunnelled into a termites' nest in a tree, or, more rarely, in an earthen bank.
Eggs (Guide)
1 - 4, usually 2; white; rounded; about 46 x 36 mm. Incubation: about 24 days beginning with the laying of the first egg; by female with helpers.
Young
Altricial, nidicolous. Fledge in about 35 days. Fed by all members of the group.
Subspecies
Long known as Dacelo gigas, but name novaeguineae (dating to same year) has priority. Species does not occur in New Guinea, and Sonnerat's first description of it from there seems to have been a deliberate falsification.
The following 2 subspecies are recognised:
novaeguineae (Hermann, 1783) - Eastern and south-eastern Australia, introduced to Tasmania, south-western WA and New Zealand.
minor Robinson, 1900 - Cape York Peninsula, south to about Cooktown.
Similar Species
In eastern and north-eastern Australia possibly with Blue-winged Kookaburra (Dacelo leachii).
