Similar species

Very similar to female MacGregor's Bowerbird, but rich blue not blue-grey leg colour, and ranges don't overlap.


Endemic to northwest New Guinea, Indonesia (Vogelkop Peninsula, Onin Peninsula, Bomberai Peninsula and Wandammen Mountains).
Widespread and common in its range.


This is a monotypic species[1].

To have grammatical consistency, the scientific name has been changed from Amblyornis inornatus to Amblyornis inornata.


Rainforest at 1000 - 2075m, mainly 1200 - 2000m. Bower sites traditionally on ridge spines and flanks with sloping ground. Avoids bare karst.



Feeds probably on fruits and insects.


Display season from July to February. A polygynous species, the male builds a bower to attract females, the female builds and attends the nest alone.
The bower is a cone-shaped hut-like tower, almost 1m high and 160cm in diameter. An entrance is propped up by two column-like sticks. Its' woven around a saplin in the centre. In the front of the hut an area of some 2 square meters is cleaned from debris and laid out with moss. On this area and around the entrance of the bower colourful flowers, fruits, dead leaves and other material are arranged as decoration.
When the female arrives the male rushes into the bower and starts to sing. Then it stands stiff and erect, occasionally running out of the bower with the head cocked to one side, then dashing in again.
The female builds a sparse nest and lays 1 egg.


A resident species.
