The bald eagle is a majestic bird of prey that serves as the national symbol of the United States of America. With its white head and tail feathers and large yellow beak, the bald eagle is easily recognizable. Wolves are apex predators that live in packs and were once found throughout much of North America before human encroachment greatly reduced their numbers. Given their iconic status, many are curious as to how the sizes of bald eagles and wolves compare.
Quick Facts on Bald Eagles
The bald eagle (Haliaeetus leucocephalus) is a large bird of prey that is native to North America. Here are some quick facts about the bald eagle:
– Wingspan: 6-7.5 feet
– Body length: 28-37 inches
– Weight: 8-14 pounds
– Lifespan: Up to 28 years in the wild
Bald eagles are found near coasts, rivers, large lakes, and other bodies of water where they feed on fish, waterfowl, and small mammals. They make very large nests called eyries high up in tall trees. Bald eagles were endangered for many decades but have made a remarkable recovery across North America.
Quick Facts on Wolves
The gray wolf (Canis lupus) is a canine predator that lives in packs and was once widespread in North America. Here are some quick facts about the gray wolf:
– Height at shoulder: 26-32 inches
– Body length: 4.5-6.5 feet
– Weight: 40-175 pounds
– Lifespan: 7-8 years in the wild
Wolves prey on large mammals like deer, elk, moose, and bison. They live in family groups called packs of around 6-8 wolves on average. Wolves communicate via body language, growls, and howls. Though their populations were decimated in the lower 48 states, gray wolf populations have rebounded in some regions in recent decades.
Size Comparison
When comparing the sizes of bald eagles and gray wolves, it is clear the two animals are quite different in size.
Wingspan
Bald eagles have wingspans between 6-7.5 feet across. An adult gray wolf standing on all four legs is only around 4.5-6.5 feet in length from nose to tail. So a bald eagle’s wings are wider than the entire body length of a gray wolf.
Weight
Bald eagles weigh 8-14 pounds on average. Gray wolves weigh between 40-175 pounds. So even a small gray wolf outweighs a bald eagle many times over.
Height
When standing, bald eagles reach heights of 30-37 inches. Gray wolves at the shoulder reach heights of 26-32 inches. So while a large bald eagle could potentially match the shoulder height of a small wolf, most wolves are still taller than eagles.
Size Comparison Table
Here is a table summarizing the size differences between bald eagles and gray wolves:
| Measurement | Bald Eagle | Gray Wolf |
|---|---|---|
| Wingspan | 6-7.5 feet | 4.5-6.5 feet body length |
| Weight | 8-14 lbs | 40-175 lbs |
| Height | 30-37 inches | 26-32 inches at shoulder |

As you can see from the image, the wolf is far larger in body size compared to the eagle.
Wingspan vs. Height Comparison
This chart compares the wingspan of a bald eagle to the height of a gray wolf standing on all fours:
| Wingspan of Bald Eagle | Height of Gray Wolf |
|---|---|
| 6 feet | 26 inches (2.2 feet) |
| 7 feet | 28 inches (2.3 feet) |
| 7.5 feet | 30 inches (2.5 feet) |
As the table shows, even a small bald eagle has a greater wingspan than the height of a gray wolf on all fours. The wingspan is one dimension where the eagle exceeds the wolf in size.
Weight Comparison
This chart compares the weight ranges of bald eagles and gray wolves:
| Bald Eagle Weight Range | Gray Wolf Weight Range |
|---|---|
| 8 lbs | 40 lbs |
| 10 lbs | 80 lbs |
| 14 lbs | 120 lbs |
| 175 lbs |
The chart illustrates how even the smallest gray wolves outweigh the largest bald eagles by significant margins. The weight difference is one of the clearest size differences between the two species.
Conclusion
In conclusion, while bald eagles have imposing wingspans, gray wolves are clearly much larger animals in terms of body size, height, and weight. An average bald eagle weighs around 10 lbs, while an average gray wolf weigh 90-110 lbs – nearly 10 times the weight of the bird. The wingspan of the bald eagle is the only dimension that can exceed a gray wolf’s body size. Overall, the two species are quite different in scale, with the bald eagle being a bird that is dwarfed in overall size by the far larger canine grey wolf. So while the bald eagle and wolf are both icons of wilderness and nature, the majestic bald eagle is definitely not as big as a wolf.
Additional Facts on Bald Eagles
Feeding Habits
– Bald eagles are opportunistic feeders and will eat fish, birds, reptiles, amphibians and small mammals.
– Fish comprise much of their diet, especially salmon in the Pacific Northwest.
– They also scavenge carrion and steal food from other birds.
– Bald eagles utilize their large talons and beaks to capture and kill prey.
Breeding and Nesting
– Bald eagles mate for life, returning to the same nesting sites annually.
– Nests are constructed from sticks and can measure up to 13 feet deep and 8 feet wide.
– Nests are usually built in tall trees near water, averaging 60-100 feet above ground.
– Females lay 1-3 eggs per year which hatch after about 35 days of incubation.
Conservation Status
– Bald eagle populations severely declined due to pesticides like DDT causing their eggshells to thin.
– The species was listed as endangered in 1967 but has recovered significantly since DDT was banned.
– Bald eagles were removed from the endangered species list in 2007 but remain protected under other laws.
– There are estimated to be over 300,000 bald eagles across North America today.
Additional Facts on Gray Wolves
Social Structure
– Gray wolves live in hierarchical packs usually consisting of a breeding pair and their offspring.
– The average pack size is 6-8 wolves but can range from 2 wolves to over 20.
– The pack has a strict social order with a dominant breeding pair.
– Wolves communicate through body language, barks, growls and howls.
Hunting Habits
– Gray wolves primarily prey on large hooved mammals like deer, elk, moose and caribou.
– They hunt in coordinated packs to take down big game that would be difficult for a single wolf.
– Wolves also eat smaller mammals like beavers, rabbits and rodents when available.
– The average gray wolf requires about 7-8 pounds of meat per day to survive.
Range and Conservation
– Gray wolf populations were decimated in the lower 48 states by the early 20th century.
– They lost 95% of their range in the continental U.S. before modern wildlife protections.
– Wolves have begun to rebound in the Great Lakes states and the northern Rockies.
– There are now roughly 6,000 gray wolves in the contiguous United States.
– The species has recovered enough to be delisted from the endangered species list in some states.
Summary and Conclusion
In summary, while the bald eagle and gray wolf are both large predators native to North America, the wolf exceeds the eagle significantly in terms of body size. The wingspan of a bald eagle can surpass the height of a gray wolf on all fours, but wolves are taller standing upright. More dramatically, gray wolves weigh approximately 10 times as much on average compared to the bird. While bald eagles weigh 8-14 pounds, gray wolves weigh 40-175 pounds fully grown. Other than wingspan, wolves exceed bald eagles in all typical measurements of animal size. Hopefully this comparison helps illustrate the size discrepancy between these two iconic but very differently-scaled North American predators. Their recovery stories show how wildlife protections can help bring back threatened species.
