The Andaman serpent eagle (Spilornis elgini) is a cool bird of prey. It's also called the Andaman dark-serpent eagle. This medium-sized bird belongs to the Accipitridae family, which includes eagles, hawks, and kites. You can only find this special eagle on the Andaman Islands in India. Sadly, its population is shrinking, and it's considered a vulnerable species. We still have a lot to learn about this eagle, like how it behaves and lives.

About the Andaman Serpent Eagle
The Andaman serpent eagle is part of a group of six serpent eagle species. Most of these eagles live only on islands. They are known as "Old World" birds because they are mostly found in Asia and Africa.
Scientists first thought the Andaman serpent eagle was a type of Crested serpent eagle. But later, they found it was its own unique species. It seems to be a bit different from the other serpent eagles. Even so, all serpent eagles are quite similar. They look alike and live in similar places. This is because they are all found in the Old World, often on islands.
What Does It Look Like?
The Andaman serpent eagle makes a call that sounds like three or four short whistles. These birds are mostly dark brown. But they have bright yellow faces and legs. You can see spots on their wings and chests. Their tails have thick black bands. The underside of their wings has white and black bands.
Like other birds of prey, they have a strong, hooked beak. This helps them tear apart their food. Young Andaman serpent eagles are lighter in color than adult birds. They also have a white head. It's hard to tell male and female eagles apart just by looking at them. They look very similar!
Where Do They Live?
The Andaman Islands are a group of over 200 islands. Most of these islands are covered in forests. The Andaman serpent eagle lives on all of these islands. They even live on very small islands, some as tiny as 0.8 square kilometers. They sometimes live on two different islands at the same time!
These eagles usually live deep inside evergreen forests. They like hillsides and tropical lowland areas. But you can also find them closer to the coast. They even visit farm areas. They build their nests in mangrove marshes and near creeks. These eagles need specific places to live and raise their young. Sadly, these important areas are now being disturbed, which puts the eagles at risk.
How Many Are There?
Even though you might see them often on the Andaman Islands, there aren't many Andaman serpent eagles in total. There are fewer than 4,000 of them. These birds live for about 8 years.
How Do They Live?
What Do They Eat?
As their name suggests, Andaman serpent eagles love to eat snakes! But they also eat other animals. This includes other birds, rats, frogs, and other reptiles. Some have even been seen eating crabs and prawns from the ground.
Serpent eagles have thick scales on their legs and short toes. Scientists think this helps them catch snakes without getting bitten. The Andaman serpent eagle hunts from high places. They often sit on tree branches below the forest canopy. When they spot food, they swoop down quickly to grab it.
How Do They Raise Their Young?
Serpent eagles are known for their amazing aerial courtship dances. This is how male and female eagles show off to each other before mating. For these birds of prey, it means both eagles fly together. They do fancy moves like locking their talons (claws) in mid-air. They also roll and dive together.
What Threats Do They Face?
The number of Andaman serpent eagles is going down. This is because of several dangers to the eagles and their homes.
- Farming: More people are moving to the islands, and they need more food. So, forests where the eagles live are being turned into farms. These farms grow crops and provide land for animals.
- Logging: The Andaman Islands have many trees. Logging companies cut down these trees for wood. This also happens because more homes and farms are needed. When trees are cut, the eagles lose their homes. Their habitat gets broken into smaller pieces.
- Hunting and Trapping: Some people hunt or trap the Andaman serpent eagle. This directly reduces the number of eagles.
- Tourism: More tourists are visiting the islands. To support tourism, new buildings are needed. This includes airports, hotels, and roads. Building these places means cutting down more forests that the eagles depend on.
- New Species: Sometimes, new animals or plants are brought to the islands. These are called "exotic species." They can be harmful to the eagles. For example, new birds might compete with the eagles for food. They might not have natural enemies, so their numbers grow fast. This makes it harder for the native eagles to find enough food.
Farming, logging, and tourism are the biggest dangers. They all destroy the eagles' natural homes. Andaman serpent eagles only live on the Andaman Islands. They do not fly to other places. This means they really need their forest homes. If they lose these homes, it's harder for them to find food and raise their young. This will cause their numbers to drop even more.
What Is Their Status?
The Andaman serpent eagle is currently listed as a vulnerable species. This means it has a small population and lives in a limited area. Because their homes are being destroyed by people moving to the islands and by logging, their numbers are expected to keep falling.
People are working to help these birds. They are watching the eagles on the Andaman Islands. They are also teaching people about the eagles and why they need protection. Important areas where the eagles live have been found. Since we don't know everything about this eagle, more studies could help us find the best ways to protect them.
