As the bird is not mentioned by any contemporary report, it was either very secretive or became extinct earlier than its congeners. Notably, it is not contained in the comprehensive listing of local fauna that Dubois made in 1671–72.
Given the bird's lack of presence in modern records, it could be either exceptionally secretive or have gone extinct earlier than its relatives. This is further supported by its absence from Dubois' comprehensive list of local fauna compiled between 1671 and 1672.
