Hunting and Diet

Prey Species

The Philippine Eagle and the American Bald Eagle are both apex predators in their respective habitats. However, their diets differ significantly due to their geographical locations and available prey species.

The Philippine Eagle primarily preys on a variety of mammals, birds, and reptiles. Its preferred prey includes monkeys, flying lemurs, civets, snakes, and large birds such as hornbills. These eagles have also been known to hunt small deer, although this is less common.

On the other hand, the American Bald Eagle predominantly feeds on fish. It is highly adapted to a diet of fish and has been observed hunting for salmon, trout, and other fish species. They are often found near bodies of water, where they can dive down and snatch fish from the surface.

Hunting Strategies

The Philippine Eagle and the American Bald Eagle employ different hunting strategies to catch their prey. The Philippine Eagle is known for its stealth and agility. It perches high up in the forest canopy and patiently waits for its prey to come within striking distance.

Once spotted, it swoops down with incredible speed and accuracy to catch its prey.

The American Bald Eagle, on the other hand, is known for its impressive aerial hunting skills. It soars high in the sky, scanning the water below for fish. When it spots a potential target, it dives towards the water, using its sharp talons to snatch the fish from the surface.

This hunting technique is called “plunging.”

Both eagles have sharp talons and strong beaks that enable them to capture and kill their prey effectively.

Feeding Ecology

The feeding ecology of the Philippine Eagle and the American Bald Eagle also differs due to their respective habitats and prey availability. The Philippine Eagle is a solitary hunter and typically consumes its prey on the spot.

It will tear its prey apart using its powerful beak and consume it immediately. However, if the prey is too large, the eagle will carry it back to its nest to feed its young.

The American Bald Eagle, on the other hand, is known for its scavenging behavior. They are opportunistic feeders and often steal food from other birds or scavenge carrion. They are also known to steal fish from other birds, such as ospreys, by harassing them until they drop their catch.

This behavior is commonly referred to as “kleptoparasitism.”

Breeding and Nesting

Mating Displays

Both the Philippine Eagle and the American Bald Eagle engage in elaborate mating displays to attract a mate. These displays are not only visually stunning but also serve as a way for the eagles to establish their dominance and fitness.

The Philippine Eagle performs an acrobatic courtship flight, soaring high in the sky while engaging in synchronized dives and loops. This display showcases the eagle’s strength and agility, impressing potential mates.

The American Bald Eagle, on the other hand, engages in a mesmerizing aerial courtship display, where the eagles lock talons mid-air and freefall together before separating just before reaching the ground. This breathtaking display is a true testament to the eagle’s grace and precision.

Nest Building

The nesting habits of the Philippine Eagle and the American Bald Eagle differ significantly. The Philippine Eagle constructs its nest high up in the canopy of large trees, usually in remote and inaccessible areas of the forest.

These nests can reach enormous sizes, with some measuring up to three meters in diameter and weighing over a ton! The eagles use branches and twigs to build the nest, which is lined with softer materials such as leaves and moss.

The American Bald Eagle, on the other hand, builds its nest in tall trees near bodies of water, such as rivers or lakes. The nest is constructed using sticks and twigs, and it is lined with softer material such as grass and feathers.

While not as large as the nests of the Philippine Eagle, the American Bald Eagle’s nest can still reach impressive sizes, measuring up to two meters in diameter.

Incubation and Chicks

Both species of eagles take turns incubating the eggs and caring for the chicks. The incubation period for the Philippine Eagle is around 58 to 68 days, while the American Bald Eagle’s incubation period is slightly shorter, ranging from 34 to 36 days.

Once the eggs hatch, the parents continue to provide care and protection for their young. The chicks of both species grow rapidly and are fully fledged within a few months. However, the Philippine Eagle chick stays with its parents for a longer period, often up to two years, while the American Bald Eagle chicks become independent after about 10 to 12 weeks.

It is fascinating to observe these magnificent birds in their natural habitats, engaging in their unique breeding and nesting behaviors. If you have the opportunity to witness their incredible displays and witness the devoted care they provide for their young, it is truly an experience that will leave you in awe.

Threats and Conservation

Historic Declines

The Philippine Eagle and the American Bald Eagle have faced significant threats throughout history, leading to a decline in their populations. The Philippine Eagle, also known as the Monkey-eating Eagle, has experienced habitat loss due to deforestation and illegal logging in the Philippines.

This loss of habitat has greatly impacted the eagle’s ability to find suitable nesting sites and prey. Additionally, hunting and trapping of the Philippine Eagle for its feathers and body parts have further contributed to its decline.

Similarly, the American Bald Eagle has faced its own set of challenges. In the 20th century, these majestic birds were on the brink of extinction due to the widespread use of pesticides, particularly DDT.

This chemical made its way into the eagles’ food chain, causing thinning of their eggshells and reproductive failure. With the ban on DDT in the 1970s and subsequent conservation efforts, the American Bald Eagle made a remarkable recovery and was removed from the endangered species list in 2007.

Current Protections
