Formerly lumped in with Trichoglossus haematodus, it is endemic to the twin islands of Biak and Superiori in the Papua province of Indonesia.

[2] As a newly separated species, specific information is scarce.

It is assumed to be similar to other Trichoglossus parakeets in preferring lowland forest including secondary growth and plantations.

[1] On Biak, forest is under heavy pressure from logging and subsistence farming.

Its population is believed to be decreasing, with fewer than 10,000 mature individuals in the wild.
