Have you ever seen an eagle carrying prey or tree branches in its talons?
You may be wondering, how much weight can an eagle carry?
Can eagles carry dogs or people?

How Much Weight Can an Eagle Carry?
But despite their wide wingspan and powerful claws, they can’t carry a lot of weight.
The exact amount of weight an eagle can carry depends on the species.
Most species can only carry a few pounds at a time.
For example, bald eagles generally weigh about 10 to 12 pounds and can carry about a third of their own weight.
So the average weight a bald eagle can carry is 3 to 4 pounds.
Some bald eagles are bigger and stronger than others; these may be able to carry a slightly higher amount of weight.
The age of the eagle can also play a role; mature eagles in their prime will be able to carry more weight than very young or very old eagles.
Another important factor is momentum – how fast the eagle flies and how much it has to slow down to lift its load.
In general, more airspeed allows them to carry more weight because their momentum aids their strength.
A bald eagle (or any eagle, for that matter) can capture a large fish or bird of prey in flight, often barely slowing their flight pattern in the process.
They can carry a heavier load this way than if they had to land first.
“An eagle that lands on the beach to grab a fish, and then takes off again, is limited to a smaller load than an eagle that swoops down at 20 or 30 miles an hour and scoops up a fish.
That momentum and speed gives the bird the ability to carry more weight.”
Regardless of the exact weight, eagles cannot travel as far with heavier loads as they can with lighter loads.
If they cannot transport a large kill all at once, they sometimes divide their prey into smaller pieces and carry them to the nest in separate pieces.
What is the heaviest an Eagle can carry?
In North America, bald eagles may be able to carry up to 7 or 8 pounds if conditions are ideal.
Golden eagles may be able to carry a little more, but even most of the largest eagles in the world will not be able to carry more than 10 or 12 pounds at once.
This giant jungle-dwelling eagle can gather up to 20 pounds at once under ideal conditions.
In order to be able to carry the maximum weight, an shingle would need the following conditions:
A high rate of speed – at least 20 to 30 miles per hour – and the ability to maintain much of that speed as they grab their intended load;
The ability to pick up the load in flight without having to land;
Of course, these ideal conditions rarely come together at once, so although eagles can carry prey and objects of unusually large weight, they rarely do.
Can an Eagle Raise a Dog?
You may have heard stories of eagles diving at dogs and carrying them off, leash and all.
It is true that some eagles may have the strength to carry some puppies, depending on the weight of the dog.
Generally, however, eagles stay away from dogs because they don’t like to get too close to people.
So, the chances of an eagle picking up your dog, even if you see them hanging around your local dog park, are extremely rare.
Even larger dogs can be at risk if they are alone, as eagles have the ability to kill much larger prey than they can carry and will take whatever they can get if they are starving.
Can an Eagle Lift a Man?
Similar to the dog stories, there were rumors of eagles rising and carrying away children, especially younger children who are still quite small.
First of all, it is highly unlikely that an eagle could lift and carry a child, as even a newborn baby would be almost too heavy for an eagle’s small frame.
Also, again, eagles are unlikely to come close to humans.
They will not risk going to adults even if they are fairly confident in their ability to carry the children.
Having said that, it is important to keep children close at all times if you live in an area with eagles.
Young eagles can swoop at very young children who become lost or separated from others in the group, which can cause serious injury.
Young eagles learn how to hunt by experimenting, by testing the limits of what they can and cannot do.
Of all the eagles, the young are most likely to try to carry children or pets, but even then, this is extremely rare and unlikely.
Which Bird Can Heaviest Weight?
Earlier in this article, we talked about the harpy eagle.
This powerful bird, which lives in Central and South America, appears to be able to carry the most weight of any flying bird.
The harpy eagle stands 3 to 4 feet tall and has a wingspan of up to 8 feet.
These eagles weigh up to 20 pounds and can carry up to their own weight if conditions are ideal.
Although harpy eagles do not usually carry 20 pounds every time they go out hunting, they will regularly carry around 10 to 12 pounds.
Harpy eagles are known to eat a wide variety of prey, including ocelots, iguanas, boa constrictors, and even caimans.

Most eagles can carry 3 to 4 pounds, although some can carry much more.
The harpy eagle, for example, can carry up to 20 pounds of weight at once.
The amount of weight an eagle can carry depends on their species, how fast they fly, how wide their wingspan is, and even how old they are.
On February 12 of 2020, a DM2 pole vaulter to the nest with a stick that looked more like a small tree!
On November 6 of 2019, Mr North dropped a stick of unknown weight, although it was clearly more than he could lift from the ground: https://youtu.be/x0Cb6S79Kz4.
And on November 4th of 2015, photographer Alex Lamine photographed the female bald eagle at Coleg Berry carrying a very large stick, which she dropped.
How much can a bald eagle carry?
Under the right conditions, just over 100% of their body weight!
We’ve speculated quite a bit about how much weight eagles can carry.
I spoke to Professor Jim Grier (he has studied birds of prey extensively and owns golden eagles), Brett Mandernack, Neil Rettig, Chuck Sindelar (a friend of Bob’s who was very involved in bald eagle recovery), Jon Gerrard (who wrote The Bald Eagle: Haunts and Habits of a Wilderness Monarch with Gary Bortolotti), and Professor David Bird (among other things, author of The Bird Almanac, A Guide To Essential Facts and Figures of the World’s Birds).
They told me that the amount of weight a bird could carry depended greatly on the situation, including:
How the object was carried.
Was it caught and carried in flight (with momentum) or picked up dead from the ground?
In the direction the object was being lifted.
Was the object being lifted up or down?
It looks like he broke off the stick somewhere above the nest and glided down instead of up.
What the eagle experts said about eagles, flight, and sticks
Grier compared eagles to airplanes and talked about the dynamics, conditions of flight, and how the object was carried: “I sometimes had the impression that my golden eagle could carry as much or more in its crop than in its feet, but no measurements were obtained ever good or write details.
For example, he could catch a large rabbit that he couldn’t fly with… but then he would eat most of it and be able to fly with a very full crop.
I think wing trim, as in aircraft, and the drag/balancing of items being carried, are important.” He added: “Flying conditions make a big difference, especially at a weight limit, as with aircraft.
The best conditions are high air pressure with a steady wind plus room and conditions for a good takeoff, all of which affect the ability to get airborne and then stay airborne.
I’ve seen bald eagles carry large fish under certain conditions, for example, that they couldn’t under other conditions.”
According to the FAA, center of gravity deviations as small as three inches can dramatically change the handling characteristics of some fully loaded aircraft.
When Jim’s golden eagle was eating a large rabbit, it was for all practical purposes ‘balancing’ the cargo in its crop, which is located in the middle of its neck above its chest.
In this case, balance was more of an issue than weight when it came to lift and stable flight.

Chuck Sindelar wrote about watching golden eagles play with sticks outside of nest building season.
A second golden eagle would follow the first up into the sky and take to a position where, when the first bird with the stick dropped it, the second bird would swoop down and grab it again, often before the stick reaches the tops of the trees below. .
Sometimes he would have to pull out of his dive and let the stick hit and go into the trees, and then the two birds would move a bit away and do this again with a new stick.” He also pointed out that although he had never seen bald or golden eagles carrying such large sticks, he had often seen them in nests.
Jon Gerrard expressed interest in how sticks are carried.
In the case of the Berry woman and DM2: “…it would be more common for an eagle to fly into an arm, usually a dead limb, and cut it off in flight.
And how far did he carry it before dropping the leg?” He told a story from the book “The Bald Eagle Haunts and Habits of a Wilderness Monarch”, which he wrote with Gary Bortolotti (pages 35 and 36)
The female regularly caught and carried Snow Geese (Blue period) – probably weighing 4.5 to 6 pounds – for up to a mile and a half to her nest.
The Geese were held aloft and the eagle managed to glide down to the nest with the goose.
The feat was likely possible because the geese were held high in the air and going to the nest was downhill.
As this eagle nests in the southern part of the range, the weight of the female would likely be between 8 and 11 pounds, so the bird would probably have been carrying around half its weight.”
Neil Rettig shared some of the observations he made filming bald eagles along the Mississippi river: “In 2015 I managed to get a nice shot on video of a Bald Eagle near Stoddard gathering a large branch from the canopy of a cottonwood tree.
I also filmed a young bald eagle 2 winters ago catching a full grown mallard in the air and having a hard time keeping it aloft.
In strong winds eagles can rise more, as Jim pointed out.
Overall, the expert panel felt that it would be unlikely, in most circumstances, for a bald eagle to carry much more than 50-60% of its body weight.
However, it could be more if the incentives and flight conditions were right: favorable winds, run-down vs. lift-off, momentum capture vs. deadlift, plenty of room to maneuver and flap, balanced load, and a highly desirable object such as a large stick or a dead fawn.
How much can birds carry?
Professor Bird provided a table from his book, The Bird Almanac, A Guide To Essential Facts and Figures of the World’s Birds, which I found absolutely astonishing!
According to his knowledge, a bald eagle should be able to carry 108% of its body weight.
Check out the American kestrel at 145%, the Pallas’s Osprey at 160%, or (Bella fans take note!) the Calliope Sparrow carrying his mate – 116% of his body weight!
Taken from his book, The Bird Almanac, A Guide to the Essential Facts and Figures of the Birds of the World.
Under favorable conditions, eagles can carry, or at least glide, around 108% of their body weight.
It probably weighed around nine pounds, although we don’t know how much the stick weighed.
But he took off at a low angle, he had to do a lot of work to gain lift, the wind was blowing from an unfavorable direction, he lost lift making a turn towards the nest, and the stick was swaying a bit, making it is more difficult. to carry
Once he dropped the stick, it was more than a mortal could pick up from the ground.
So why did DM2 bring in a heavy stick when Mr. North and the woman from Berry College?
Those two eagles may have had ideal conditions for breaking sticks (favorable winds and plenty of space), but they were trying to lift heavy sticks, with the poor balance with the weight to one side.
Their sticks quickly collapsed to hang like a weight under each shingle, causing them to roll, pitch, and lose lift.
Sudden changes in center of gravity are never a good thing, especially when the object you’re flying with weighs more than you!
DM2 seemed to be gliding down, not rising, and his path was taking him – and his huge stick – into the nest!
Big thanks to Jim Grier, Chuck Sindelar, Jon Gerrard, David Bird, Brett Mandernack, and Neil Rettig for talking to me!
