There are two main types of crested eagles: Sea Eagles and Snake-eagles. These two groups of eagles differ in their habitat, prey, and physical characteristics.
Sea Eagles: The Fish-Hunting Raptors
Sea Eagles, also known as fish eagles, are large birds of prey that primarily feed on fish. They can be found on every continent except South America and Antarctica, living near water bodies such as rivers, lakes, and coastal areas. Some notable species of Sea Eagles include:
- White-bellied Sea-eagle
- African Fish-eagle
- Bald Eagle
Sea Eagles have powerful talons and beaks that are well-suited for catching and tearing apart their aquatic prey. They are known for their impressive hunting skills, often swooping down from the sky to snatch fish from the water’s surface.
Snake-eagles: The Reptile Specialists

Snake-eagles, on the other hand, are medium-sized raptors that specialize in hunting snakes and other small reptiles. They are found in tropical parts of Asia and Africa, where they can take advantage of the diverse snake populations. Some examples of Snake-eagle species include:
- Short-toed Snake-eagle
- Black-chested Snake-eagle
- Crested Serpent-eagle
Snake-eagles have adapted to their specialized diet, with strong legs and sharp talons that allow them to effectively capture and subdue their slithering prey. They are often seen soaring over grasslands and forests, searching for their next meal.
Other Types of Eagles
In addition to the Sea Eagles and Snake-eagles, there are several other groups of eagles, including:
- Booted Eagles: Comparable in size to a common buzzard or red-tailed hawk
- Solitary Eagles: Known for their solitary behavior
- Golden Eagles, Bald Eagles, and African Fish Eagles: Some of the most well-known eagle species
These eagles can be found in various habitats, from open grasslands to dense forests, and they prey on a wide range of animals, from small rodents to large mammals.
Characteristics of Eagles
Eagles are large, powerful birds of prey with several distinctive features:
- Heavy heads and beaks for ripping flesh from their prey
- Strong, muscular legs and powerful talons
- Extremely powerful eyesight, with an estimated visual acuity twice that of a typical human
- Females are larger than males
- They build their nests, called eyries, in tall trees or on high cliffs
Eagles are apex predators in the avian world, and their hunting strategies and prey preferences vary depending on the genus and species.
In conclusion, there are two main types of crested eagles: Sea Eagles and Snake-eagles. Sea Eagles are specialized in hunting fish, while Snake-eagles primarily target snakes and other reptiles. These two groups of eagles, along with several other types, make up the diverse and impressive world of eagles.
