The grey-winged trumpeter is a ground bird closely related to cranes and rails. It is a poor flier and prefers to run from danger.
What They Eat
Grey-winged trumpeters eat insects, fallen fruits, and vegetable matter.
Where They Live
These birds inhabit the tropical forests of the Northern Amazon and Guiana Shield in South America.
What They Do
Trumpeters are very social birds and often travel in groups of 5-8 individuals. There is typically one female in the group and the rest are males. When not in breeding season, trumpeters can form groups of up to 50 individuals.
How They’re Doing
Due to deforestation of the Amazon rainforest, populations of grey-winged trumpeters are decreasing. Populations are also decreasing due to hunting. They are easy hunting targets due to their lack of flying abilities.
-Indigenous people often keep trumpeters as pets. The trumpeter’s loud alarm call can alert people to the presence of snakes or other predators.
-The grey-winged trumpeter’s name was comes from the grey color of some of their wing feathers.
-Trumpeters are cavity nesters and lay their eggs in hollow trees.
-Courtship displays involve elaborate dancing, jumps, and even somersaults.
Grey-winged trumpeter populations are decreasing due to deforestation and hunting. Forests of the Amazon River basin are being cleared for roads, cattle ranching, and crop production. The trumpeter’s poor ability to fly also leaves them prime targets for hunters. Trumpeters are likewise commonly caught and kept as pets due to their natural “guard dog” like behavior.
