Despite their elusive behavior, the Grass Green Tanager has a loud and distinct call, making it easier for birders to locate them in the wild. Their call is a series of high-pitched, fast-paced notes that can be heard echoing through the forest.

Threats and Conservation Status

As with many species in the animal kingdom, the Grass Green Tanager's habitat is under threat due to human activities. Deforestation, specifically for agriculture and urbanization, has resulted in the loss and fragmentation of their natural habitat.

These birds are also captured for the pet trade, which has further contributed to their declining population. However, their population is not yet considered endangered, and they currently hold a conservation status of "Least Concern" on the IUCN Red List.
