Their interesting name probably originates from the deep low sounds they use to communicate. One sound is used as a flocking call while the other is a threatening call.
Grey-winged trumpeters are non-migratory terrestrial birds.
These birds perform elaborate and noisy courtship dances involving strutting, leaping, and even somersaults in their excitement.
These birds are polyandrous, meaning that the females may mate with more than one male.
Grey-winged trumpeters rarely fly, but can run fast if necessary.
Ecology and Conservation
The primary threat to this species is accelerating deforestation in the Amazon basin as land is cleared for cattle ranching and soy production, facilitated by expansion of the road network.
In some areas, trumpeters are considered game birds. They do not seem to fear humans, nor are they good fliers. This makes them prime targets for hunters.
In some parts of their range, grey-winged trumpeters have been hunted to extinction.
