Common Black Hawk

The common black hawk (<em>Buteogallus anthracinus</em>) is a medium-sized raptor of the family Accipitridae, classified as Least Concern on the IUCN Red List. It inhabits aerial, terrestrial, and aquatic environments across its range, which includes Colombia, Ecuador, Venezuela, and, notably, Norway, suggesting occasional vagrant or introduced occurrences outside its core Neotropical distribution. <em>Buteogallus anthracinus</em> is typically associated with riparian forests, mangroves, and wetland edges, where it hunts crabs, fish, frogs, and other aquatic prey along stream banks and shorelines. The bird is predominantly black with a broad white tail band, making it distinctive in the field. It often perches conspicuously on exposed branches near water, scanning for prey below. The species typically nests in tall trees near water, constructing large stick nests used across multiple breeding seasons. Biological traits of this species remain poorly documented in the scientific literature.
