Eagle Enemies: 13 Creatures That Prey on These Birds of Prey

Eagles are often seen as the kings of the sky, soaring majestically above the landscape. But even these powerful birds face threats from other animals. While eagles are fierce hunters, they’re not invincible. In fact, several creatures see them as potential meals or competitors. From crafty mammals to surprising insects, the list of eagle predators might shock you. Ready to discover which animals dare to take on these iconic birds? Here’s a look at 13 creatures that aren’t afraid to challenge eagles.

Great Horned Owls

Great horned owls are formidable nighttime hunters that sometimes target eagle chicks and eggs. These silent flyers can swoop into nests undetected, making them a real threat to young eagles. Adult eagles are usually safe from owls, but nesting sites require constant vigilance against these nocturnal predators. Great horned owls have been known to successfully prey on eaglets of various species, including bald eagles and golden eagles.

Bears

Bears, especially grizzlies and black bears, may raid eagle nests for eggs or chicks. These large mammals are excellent climbers and can reach nests high up in trees. While adult eagles can usually escape, their young are vulnerable to these opportunistic omnivores. In areas where bears and eagles coexist, such as Alaska and parts of Canada, bear predation can significantly impact eagle breeding success.

Wolverines

Wolverines are fierce and determined hunters that will go after eagle nests if given the chance. These muscular members of the weasel family are surprisingly agile climbers. They’re known to scale cliffs and trees in search of food, including eagle eggs and chicks. Wolverines’ strength and tenacity make them formidable opponents, even for adult eagles trying to defend their nests.

Raccoons

Raccoons are clever and nimble creatures that can easily access eagle nests. Their dexterous paws allow them to manipulate eggs and small chicks. Nesting eagles must be on high alert for these nocturnal raiders, which can quickly decimate a clutch of eggs or young birds. Raccoons are particularly problematic for eagles nesting in urban or suburban areas, where these adaptable mammals thrive.

Crows and Ravens

Crows and ravens are intelligent birds that often harass eagles, especially near nesting sites. While they’re unlikely to take down an adult eagle, they may steal eggs or attack chicks if left unguarded. These corvids often work in groups, mobbing eagles to drive them away from their territories. Their persistent harassment can force eagles to abandon nests or hunting grounds, indirectly affecting eagle populations.

Hawks

Some larger hawk species, like the goshawk, may attack eagle chicks or compete with eagles for food. While not typically a threat to adult eagles, hawks can be fierce rivals in shared hunting grounds. They may also opportunistically raid eagle nests when the parents are away. In some cases, hawks have been observed engaging in aerial battles with eagles over territory or prey.

Golden Eagles

Interestingly, golden eagles sometimes prey on other eagle species, particularly their young. These powerful birds are known to attack the nests of bald eagles and other raptors. In areas where their ranges overlap, golden eagles can be a significant threat to other eagle populations. Golden eagles have even been documented killing adult bald eagles in rare instances of direct competition.

Foxes

Foxes are opportunistic predators that will raid eagle nests if they can reach them. While they can’t climb as well as some other predators, foxes may access nests built on cliffs or low in trees. Their keen sense of smell helps them locate nests, making them a potential threat to eagle eggs and chicks. Foxes are particularly dangerous to ground-nesting eagle species or those that build nests on low cliff ledges.

Snakes

Some large snake species, like pythons and rat snakes, can climb trees and prey on eagle eggs or chicks. These stealthy reptiles can slither into nests without alerting the parents. In some regions, snakes pose a significant risk to nesting eagles, especially in warmer climates. Certain constrictor species have been known to consume not only eggs and chicks but also occasionally attempt to prey on adult eagles.

Lynx

Lynx are agile wildcats that can climb trees and may occasionally target eagle nests. While they’re more likely to hunt on the ground, lynx have been known to go after bird nests when the opportunity arises. Their sharp claws and excellent balance make them capable of reaching even high nests. In boreal forest regions, where lynx and eagles share habitats, these cats can be a notable threat to nesting raptors.

Parasitic Insects

Tiny but troublesome, parasitic insects like mites and flies can seriously harm eagle chicks. These pests feed on the blood of young birds, weakening them and potentially causing death. While not predators in the traditional sense, these insects can be a significant threat to eagle populations. Heavy infestations of parasites can lead to reduced fledging success and even complete nest failure in severe cases.

Humans

Unfortunately, humans remain one of the biggest threats to eagles. Habitat destruction, pollution, and illegal hunting all put pressure on eagle populations. While many countries now have laws protecting eagles, human activities continue to impact these birds in various ways. Collisions with vehicles, power lines, and wind turbines also pose significant risks to eagles in many areas.

Other Eagles

In some cases, eagles may be their own worst enemies. Territorial disputes between eagles can turn deadly, with stronger birds sometimes killing weaker ones. This is especially true when food is scarce or during breeding season when competition for mates and nesting sites is fierce. Intraspecific aggression can lead to injuries or fatalities, particularly among younger or less experienced eagles competing for limited resources.
