White-tailed eagles and fish eagles are two of the most impressive birds of prey, captivating the attention of birdwatchers and nature enthusiasts worldwide. While they share some similarities, these two species have distinct characteristics that set them apart. In this comprehensive blog post, we’ll explore the key differences between white-tailed eagles and fish eagles, covering their size, appearance, habitat, diet, and conservation status.
Size and Appearance
White-tailed eagles are among the largest birds of prey, with a length of 66-94 cm (26-37 in) and a wingspan of 1.78-2.45 m (5.8-8.0 ft). They have a distinctive brown plumage with a white tail and head, as well as a bright yellow beak and legs.
In contrast, fish eagles are smaller, with a length of 55-65 cm (22-26 in) and a wingspan of 1.2-1.5 m (4-5 ft). They have a brown head and chest, a white belly and underwing coverts, and a dark beak and legs.
Habitat and Distribution

White-tailed eagles are found in riverine and coastal habitats throughout Europe, Asia, and North America, preferring areas near water where they can find abundant fish and other aquatic prey.
Fish eagles, on the other hand, are native to the tropical regions of Africa and Asia, where they inhabit forests, wetlands, and coastal areas, thriving in a more humid and warm climate.
Diet and Hunting
White-tailed eagles are opportunistic feeders, consuming a wide variety of prey, including fish, birds, mammals, and carrion. They have powerful beaks and talons that enable them to catch and kill their prey, as well as to tear flesh and bones.
Fish eagles, as their name suggests, specialize in hunting fish, which they catch by diving into the water from a height or by snatching them from the surface. They have a reversible outer toe and a spiny sole that help them grip slippery fish and provide traction on wet surfaces.
Conservation Status
White-tailed eagles were once threatened by habitat loss, persecution, and pollution, but their populations have recovered in many regions thanks to conservation efforts. They are currently classified as a species of Least Concern by the IUCN.
Fish eagles, however, face different threats, such as habitat fragmentation, overfishing, and human disturbance. They are listed as Near Threatened by the IUCN, indicating a need for continued conservation efforts to protect their populations and habitats.
