Use Trade

This species is found in the pet trade and populations from Indonesia are subject to CITES quotas.

Yuwono (1998) recorded the trade of this species from Indonesian New Guinea, and that thousands of specimens could be collected if required.

Natusch and Lyons (2012) noted the trade of this species from Jayapura and the Vogelkop in Indonesian New Guinea. Fifteen and forty-four individuals respectively were recorded at wildlife traders between September 2010 – April 2011. The quota for this species was 500 from Papua and 800 from West Papua.

There is no quota from Papua New Guinea.
