The largest species of eagle is the Steller's Sea Eagle (Haliaeetus pelagicus), which is native to the coasts of northern Japan, Russia, and Korea. It can weigh between 3 to 7.5 kilograms (6.6 to 16.5 pounds) and has a wingspan of up to 2.5 meters (8.2 feet). Steller's Sea Eagle is known for its striking appearance, featuring a massive yellow beak and dark brown plumage. This powerful bird primarily feeds on fish, particularly salmon, as well as other marine life. Due to habitat loss and environmental threats, its population is considered vulnerable, highlighting the need for conservation efforts to protect its natural habitat.
