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.

Common Seal

The most widely distributed pinniped, harbor seals inhabit temperate and subarctic coastal waters of both the North Atlantic and North Pacific. Adults reach up to 130 kg and spend roughly equal time at sea hunting fish, squid, and crustaceans and hauling out on beaches or rocks to rest. Their large, expressive eyes are adapted for underwater vision in low light. Harbor seals are a critical food source for orcas, sharks, and polar bears.
