Range
Common trumpeters are found in northwestern Brazil as well as portions of Colombia, Ecuador, Peru, Venezuela, and the Guianas.
Habitat
Common trumpeters are found in dense areas of tropical rainforest.
Reproduction
The common trumpeter is generally found in groups of three to twelve individuals. A single dominant female mates with as many as three dominant males. Three eggs are laid at a time, usually in a hole in a tree. Eggs hatch after approximately twenty-eight days. All adults in the group help in feeding and caring for the offspring.
Feeding habits
Common trumpeters eat fruit, mostly that which has been knocked to the ground by monkeys. They also eat some insects, particularly beetles, ants, and termites.
Conservation
This species has a large range, with an estimated global extent of occurrence of 2,800,000 km2. The global population size has not been quantified, but the species is not believed to approach the thresholds for the population size criterion of the IUCN Red List (i.e., less than 10,000 mature individuals in conjunction with appropriate decline rates and subpopulation qualifiers), even though the species is described as ‘uncommon’ in at least parts of its range (Stotz et al. 1996). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
Migration
Sedentary in all of its range.
