The black-winged trumpeter (Psophia obscura), also called the dusky trumpeter, is a species of bird in the family Psophiidae.

It was formerly listed as a subspecies of the dark-winged trumpeter but is now considered a separate species.

It only has a population of about 50–250 individuals, with its small population continuing to decrease.

[1] This species is vulnerable to hunting and its population may be so low that it is likely split into two subpopulations.
