Lykkers, the white-bellied sea eagle is one of nature’s most impressive raptors. Known for its striking appearance and powerful presence, this bird dominates the skies along rivers, lakes, and coastal regions.

First described by Johann Friedrich Gmelin in 1788, it is closely related to the Sanford’s sea eagle from the Solomon Islands. Together, they form a fascinating superspecies that amazes birdwatchers worldwide.

The white-bellied sea eagle is instantly recognizable, with its pure white head, chest, underwing coverts, and tail contrasting beautifully against its gray upper parts and black flight feathers.

Size and Appearance

These eagles are large and majestic. Female white-bellied sea eagles are bigger than males, measuring up to 90 cm (35 inches) long, with a wingspan of about 2.2 meters (7.2 feet), and weighing nearly 4.5 kg (9.9 lbs). Juveniles have brown feathers which gradually turn white as they reach five or six years old. Their loud, goose-like calls make them easy to detect even before we spot them soaring above. Watching them glide with such effortless grace is a breathtaking experience that reminds us of the wild beauty of nature.

Habitat and Range

White-bellied sea eagles are found from Sri Lanka, across Southeast Asia, and throughout Australia. They prefer living near water, which provides both food and nesting opportunities. Fish make up about half of their diet, but they are opportunistic feeders, eating carrion and other animals as well. We often find them perched high in trees overlooking rivers or gliding elegantly above estuaries, scanning the water for their next meal. These habitats offer the perfect setting for observing their hunting skills and majestic flight patterns.

Diet and Hunting

Fish are their main prey, but white-bellied sea eagles are adaptable hunters. They swoop down from high perches or glide low over the water to catch fish with their sharp talons. Their hunting strategy is both patient and precise. In addition to fish, they may feed on small mammals, birds, or even carrion when the opportunity arises. Observing their hunting technique gives us insight into their intelligence and adaptability in the wild.

Conservation Status

Globally, white-bellied sea eagles are classified as Least Concern by the IUCN. However, populations are declining in some areas of Southeast Asia and southeastern Australia. In Victoria, they are considered threatened, and in South Australia and Tasmania, they are vulnerable. Human disturbance near nesting sites and removal of large trees suitable for nesting are the main threats. We can help protect these eagles by preserving their habitats and minimizing disruption in key nesting areas.

Cultural Significance

White-bellied sea eagles are not just stunning predators—they are deeply respected by Indigenous Australians and feature in many traditional stories. They symbolize strength, keen vision, and a connection to nature. Seeing one in flight can feel like witnessing a living legend, connecting us to generations of folklore and local traditions. For nature enthusiasts, spotting a white-bellied sea eagle is always a memorable and inspiring experience.

How to Spot Them?

If we want to see a white-bellied sea eagle, rivers, lakes, and coastal areas are the best spots. Early morning or late afternoon is ideal when they are most active. Look for the distinctive white head and chest, gray upperparts, and black wing feathers. Binoculars help, but patience is key. Once we spot one, take a moment to enjoy its powerful glide and unique call—an experience that reminds us why nature is so incredible.

Soaring Above

Lykkers, the white-bellied sea eagle is a true marvel of the skies. From its striking appearance to its hunting prowess and cultural significance, it embodies the beauty and resilience of wildlife. Next time we explore rivers or coasts, keep an eye on the horizon—you might just catch a glimpse of this majestic sea eagle soaring above, a living symbol of freedom and strength.
