The Northern Screamer (Chauna chavaria) is a large, goose-like bird native to the wetlands of Colombia and Venezuela. It is known for its distinctive loud calls and spiky crown feathers. This species thrives in marshy areas where it feeds on plant material and plays a crucial role in local aquatic ecosystems.

Chauna chavaria, commonly known as the Northern Screamer, is native to northern South America. Its geographical distribution is primarily in Colombia and Venezuela, particularly in the lowland regions near the Orinoco River basin and the northern parts of the Amazon basin.

The Northern Screamer inhabits wetland environments, including marshes, swamps, and wet savannas. These areas are characterized by freshwater bodies, dense aquatic vegetation, and a humid tropical climate with high annual rainfall and warm temperatures.

As a wetland bird, the Northern Screamer plays a role in the ecosystem by feeding on aquatic plants and occasionally small invertebrates. Its presence indicates a healthy wetland ecosystem, and it may contribute to the dispersion of plant seeds through its droppings. The species is adapted to life in shallow waters and dense vegetation, which provides cover from predators.
