With its snowy white head and intimidating large stature, the bald eagle conjures images of power and dominance. As the national symbol of the United States, this regal bird seems untouchable. But even bald eagles have natural predators that threaten them in the wild.
If you’re short on time, here’s a quick answer: The main predators of bald eagles are other eagles, large owls, coyotes and foxes. However, bald eagle predation is rare overall.
In this comprehensive guide, we’ll take a deeper look at what eats bald eagles. We’ll overview their role in the food chain, highlight their known predators, and examine how age, habitat and other factors influence bald eagle survival rates when facing these threats.
Bald Eagles’ Place in the Food Chain
The bald eagle, America’s national symbol, holds a unique place in the food chain as an apex avian predator. With their sharp talons and powerful beaks, these majestic birds of prey are formidable hunters.
They primarily feed on fish, using their keen eyesight to spot prey from high above and their impressive diving skills to snatch fish from the water’s surface. However, bald eagles are opportunistic feeders and will also scavenge on carrion and prey on small mammals and birds.
Role as apex avian predator
As apex predators, bald eagles play a crucial role in maintaining the balance of ecosystems. By controlling populations of smaller prey species, they help prevent overpopulation and maintain biodiversity.
Their presence also affects the behavior of other animals, as many species modify their activities or habitats to avoid becoming prey. It is fascinating to see how these magnificent birds have adapted to become top predators in their environment.
Threats differ for juveniles vs adults
While bald eagles are powerful predators, they are not without their own threats. Juvenile bald eagles, in particular, face challenges as they learn to hunt and survive on their own. They may fall victim to larger birds of prey, such as golden eagles or great horned owls, who see them as competition or easy prey.
Additionally, human activities, such as habitat destruction, pollution, and collisions with power lines, pose significant threats to bald eagle populations.
According to a study conducted by the National Wildlife Federation, collisions with power lines account for a significant number of bald eagle deaths each year. These collisions can result in electrocution or severe injuries.
Organizations like the American Bird Conservancy are working tirelessly to reduce these collisions by advocating for the use of bird-safe power lines and promoting education to raise awareness about the issue.
Avian Predators of Bald Eagles
Territorial battles with other eagles
Bald eagles, with their majestic appearance and powerful presence, are often seen as the kings of the skies. However, even these regal birds are not immune to threats from other avian predators. One of the biggest challenges they face is territorial battles with other eagles.
Bald eagles are known for their fiercely territorial nature, and clashes between them can be intense and dramatic.
These territorial battles usually occur when two adult eagles, often males, vie for the same territory or nesting site. They engage in high-speed aerial duels, locking talons and spiraling towards the ground before breaking apart at the last moment.
These battles can be both physically and mentally draining for the eagles involved, and injuries are not uncommon. In some cases, the weaker eagle may be forced to retreat and find a new territory.
Owl attacks at nesting sites
Another avian predator that poses a threat to bald eagles is the owl, particularly the great horned owl. These large and powerful owls are known for their stealth and agility, making them formidable opponents for bald eagles.
Great horned owls are known to attack bald eagles, especially when they are nesting. They target both adult eagles and their young, swooping in silently under the cover of darkness. The element of surprise gives the owl an advantage, and it can inflict serious injuries with its sharp talons and powerful beak.
In some cases, the bald eagle’s nest may be completely taken over by the owl, leading to the abandonment of the site by the eagles. This can be a devastating blow, as bald eagles invest a significant amount of time and effort in building and maintaining their nests.
It’s important to note that while territorial battles and owl attacks are threats to bald eagles, they are not the primary cause of their decline in numbers. The major factors contributing to the decline of bald eagle populations include habitat loss, pollution, and human disturbance.
Efforts to protect and conserve these majestic birds are crucial for their survival.
Mammalian Predators of Bald Eagles
Bald eagles are often seen as majestic and powerful birds, but they are not without their own predators. While they may be at the top of the avian food chain, there are a few mammals that pose a threat to these iconic birds.
Coyote attacks on ground-feeding eagles
Coyotes are known for their opportunistic feeding habits, and this includes preying on bald eagles. Although coyotes primarily feed on smaller mammals like rabbits and rodents, they have been observed attacking ground-feeding eagles.
These attacks are more likely to occur when the eagles are scavenging on carrion or feeding on fish near the water’s edge. Coyotes are cunning and adaptable predators, and they can pose a significant threat to bald eagles, especially when they are vulnerable during feeding.
Fox raids on unattended nests
Foxes are another mammalian predator that can pose a danger to bald eagles. While bald eagles typically build their nests in tall trees or on cliffs, there are occasions when they may leave their nests unattended.
This is when foxes seize the opportunity to raid the nests and steal eggs or young eaglets. Foxes are known for their agility and stealth, making them capable of sneaking into these nests undetected. Bald eagles must be vigilant in protecting their nests and young from these opportunistic predators.
It is important to note that these mammalian predators are not the primary threat to the overall bald eagle population. The main dangers to bald eagles come from habitat loss, pollution, and human activities, such as illegal hunting and disturbance of nesting sites.
However, understanding the natural predators of bald eagles helps us appreciate the challenges these majestic birds face in their daily lives.
Other Threats and Risk Factors
While predators may be a significant threat to the bald eagle, there are other factors that can also pose risks to this majestic bird’s survival. Let’s take a closer look at some of these threats:
Although the bald eagle is a formidable predator itself, it can still face the risk of starvation. Factors such as the depletion of its prey population or competition with other scavengers can lead to a lack of food for the eagle.
This is especially concerning during the winter months when the availability of food can be limited.
As the bald eagle’s habitat often overlaps with human-populated areas, vehicle collisions can be a significant threat to their population. These collisions can result in severe injuries or fatalities for the birds.
It is crucial for drivers to be aware of their surroundings and exercise caution when driving in areas where bald eagles are known to reside.
Lead poisoning is a serious concern for bald eagles and many other birds of prey. This occurs when eagles consume prey that has been shot with lead-based ammunition. The lead fragments can poison the eagles, leading to severe health issues or even death.
Efforts have been made to encourage the use of non-toxic ammunition to reduce this threat.
The destruction of natural habitats is a significant risk factor for the bald eagle. Urbanization, deforestation, and pollution can all have detrimental effects on their nesting sites and food sources.
Conservation efforts and the protection of their habitats are crucial to ensure the survival of this iconic bird.

Despite having few natural predators, bald eagles face a variety of threats ranging from large owls to lead poisoning. Their status as apex predators helps mitigate risks, especially for mature adults.
Understanding what preys upon these iconic birds can inform conservation efforts and help preserve America’s majestic national emblem.
