Table of Contents

Have you ever wondered how many types of eagles exist around the world?

There are 68 types of eagles flying around the world. Yes, 68! These powerful birds are divided into four main families, each with unique and incredible traits. What’s interesting is how different each species can be and how they share certain qualities if they belong to the same family.

For example, did you know the Philippine Eagle is considered one of the largest and most powerful eagles, with a wingspan that can stretch up to 7 feet? 

These fascinating creatures continue to intrigue me, from their sharp eyesight, capable of spotting prey from miles away, to their impressive wingspans, which can reach up to 8 feet for some species! 

Let me share everything I gathered from years of eagle obsession. 

1. Snake Eagles

Let’s start by exploring these mid-sized raptors mainly found in Africa. I’ve been awestruck more than once by their impressive hunting skills. They use their long legs and sharp claws to catch reptiles. That’s where they get their nickname from—their slippery prey. 

While perched high up on a tree branch, Snake eagles can spot a snake slithering through the grass. What follows always amazes me. With lightning speed, the eagle would swoop down and snatch their prey using strong talons. 

Snake eagles are an important part of their ecosystem because they keep the snake population under control. Without them, the slithering predators would cause an imbalance in the food chain!

2. Brown Snake Eagle (Circaetus Cinereus)

Mostly found in savannas and open woodlands, this expert hunter is one of my favorite eagles to watch. It’s a fairly large species, about 30-ish inches long. As with other eagles, the wingspan is where it shows its impressive size—up to 6 feet 7 inches! 

If you’re lucky to spot a Brown Snake Eagle flying above, you’d see pale underparts and a relatively short tail. But that’s now how they typically hunt. Usually, I spot them perched on an elevated high branch for a better view. They typically feed on snakes and other reptiles; hence the name. 

Using their strong talons and sharp beak, they are experts at capturing and subduing their slippery prey.

3. Black-Chested Snake Eagle (Circaetus Pectoralis)

The Black-Chested Snake Eagle is a captivating sight, mostly found in savannas and sub-Saharan Africa’s open woodlands. I was always impressed by the contrasting plumage of this expert hunter. Its black chest band stands out against its pale underparts, making it an easy bird to spot. 

With a wingspan of up to 5 feet 7 inches, it’s a formidable predator, specializing in hunting snakes and other reptiles. It also uses the same hunting style of scanning the grounds from high branches. Of course, it also has keen eyesight and sharp talons that help it catch snakes before they slither away from its grasp. 

4. Short-Toed Snake Eagle (Circaetus Gallicus)

The Short-Toed Snake Eagle is a mesmerizing bird of prey found in various habitats across Europe, Asia, and North Africa. It blends seamlessly into its surroundings, with dark brown plumage and pale underparts. 

This eagle is about 22-26 inches long, with a wingspan of up to 6 feet. I’ve always thought that’s a wide wingspan for such a small body. The Short-toed Snake Eagle excels in hunting snakes and reptiles, again using its claws and beak to capture and control its prey. 

Whether perched on lofty branches or gliding above an expansive landscape, I think that this eagle embodies grace and effectiveness in its natural habitat.

5. Western Banded Snake Eagle

It’s a mid-sized eagle, about 25-29 inches long. Once, I had the pleasure of handling one and was surprised that it was not that heavy—just about 4 pounds.

6. Fasciated Snake Eagle

This is a fascinating bird of prey with a unique feather pattern. It’s easily recognizable as the stripes run across the eagle’s body. It also has a fairly large wingspan reaching up to 5.9 feet, with a mid-sized body of around 26 inches and 4 pounds. 

It is a skilled hunter, preying on snakes and small mammals with its sharp talons and keen eyesight.

In my view, this eagle is a true marvel of nature, blending camouflage and hunting prowess to thrive in its environment.

Named for the distinctive crest on its head, this eagle is a skilled hunter of snakes and lizards, using its sharp talons and powerful beak to capture prey. It is often seen soaring above forests, scanning for movement below. In my opinion, the Crested Serpent Eagle is a symbol of grace and power, showcasing nature’s intricate design for survival in diverse ecosystems.

8. Philippine Serpent Eagle (Spilornis Holospilus)

This is a medium-sized eagle native to the Philippines, measuring about 18-22 inches in length with a wingspan of 43 to 51 inches. 

It inhabits forests and wooded areas, preying on snakes, lizards, and small mammals. Perched on branches, it scans for prey using its sharp talons and beak. 

This eagle’s distinctive dark brown plumage with white markings and its unique call make it a captivating species.

Known for their impressive fishing skills, these small eagles prefer to feed mainly on fish. Many experts debate on whether they are different from sea eagles because their size is drastically smaller. However, their plumage is very similar—gray heads that slowly fade into dull brown feathers on their bodies and wings. Their bellies are white, like the sea eagles. 

Besides their smaller size, I can tell these eagles apart from sea eagles by the color of their tails. Fish eagles are native to Southeastern Asia, and I’ve often spotted them in the Indian subcontinent during my travels. Let’s take a better look at each one:

11. African Fish Eagle

African Fish Eagle

 

I find its appearance striking—a white head and tail feathers contrasting with dark brown plumage on the body. Yes, that’s similar to the plumage of the iconic Bald Eagle of America.

In my opinion, watching the African Fish Eagle dive gracefully into the water to catch fish is a mesmerizing experience, highlighting the beauty and resilience of nature’s predators in their aquatic habitats. 

12. Grey-Headed Fish-Eagle (Ichthyophaga Ichthyaetus)

This is yet another stunning bird of prey, with distinctive gray head and neck feathers that stand out against the white underparts and dark wings. The Grey-Headed Fish Eagle is native to Southeast Asia.

It’s a smaller eagle, measuring about 24-28 inches in length with a wingspan of 63-71 inches. Yet, I think it is an adept fish hunter. I’ve had the pleasure of seeing this eagle use its sharp talons and hooked beaks to catch prey from rivers and lakes. It swoops down and snatches fish right out of the water, with incredible precision. 

13. Sea Eagles

These are fascinating birds that typically live by the sea (or lakes). They are closely related to the “fish eagles” I mentioned earlier. Their sharp eyes help spot fish swimming below them as they soar high.  They also eat waterfowl, hunting them in much the same way that they fish.

I always found it thrilling to watch a sea eagle swoop down at top speed when it’s fishing. With a swift and agile movement, they use their strong claws to grab it from the water.

Sea eagles are found all over the world, except for South America. Although this group includes the infamous Bald Eagle, I’ve chosen to focus on lesser-known types worth studying.
