What Weight Can Falcon Bird Lift and Continue Flying
If you've seen videos or heard stories of eagles swooping down to grab or attack large animals, you know how scary that can be. The thought of a large bird snatching and carrying away your child or pet is the stuff of nightmares. So, now, you're probably wondering, how much can a bird even lift?
The heaviest recorded and verified weight a bird can lift is 15 pounds, held by the bald eagle for lifting a mule deer fawn of the said weight. However, many experts claim that birds can't carry more than half their weight in flight unless the wind conditions favor them.
What Birds Can Carry the Heaviest Weight?
Eagles are the only birds that carry the heaviest weights. Most of them can lift off anything from 5 to 6 pounds from flat ground.
Eagles with the greatest weight-carrying capacity are the bald eagle, the Philippine eagle, the harpy eagle, and the crowned eagle.
These eagles may carry more off the ground depending on their mode of flight and the wind conditions.
However, if the prey is too heavy, they may drag it to a safe place where they dismember it into manageable pieces before consuming or taking it to their nests.
Since each eagle has different wing and flight characteristics, it's worth exploring these birds and knowing how much they can carry.
The Bald Eagle
With the bald eagle being the national emblem of the United States, one can only imagine how powerful, majestic, and independent this bird is.
Characterized by its dark brown plumage and white head and tail, the bald eagle has highly developed and powerful talons for attacking and piercing its prey.
It weighs between 6.6 and 13.9 pounds and measures 28 – 40 inches, which is naturally intimidating for its prey.
Talking of prey, bald eagles mainly feed on fish, but their diet also consists of birds and mammals.
There have been cases where bald eagles were recorded preying on livestock, with some weighing as much as 24 pounds.
In one case, a bald eagle killed an adult, pregnant ewe, which weighed more than 132 pounds.
However, they can't lift this much weight and have only been proven to carry up to 15 pounds, which is the heaviest load recorded and verified for any flying bird.
The bald eagle can carry this much weight because of its wingspan – between 71 to 90 inches – and its diving speed between 75 – 99 mph.
The Harpy Eagle
Although the harpy eagle only weighs between 13 to 20 pounds, it is considered the world's most powerful bird of prey.
It has distinguishable slate-black feathers on its upper side and white on its underside.
It also has a distinctive bold look with a pale grey head and a black band across its upper breast.
In terms of body length, the harpy eagle measures between 34 – 42 inches and has a wingspan of 69 – 88 inches.
The harpy eagle's legs and talons are the thickest and largest of any bird of prey.
This extraordinary physical characteristic means that it won't settle for small animals. Instead, it focuses more on mammals like sloths and monkeys.
With its deadly talons, the harpy eagle can carry prey as heavy as its weight.
Males have mostly been recorded to carry about half their weight or medium-sized prey.
An adult female harpy can snatch like sloths and monkeys weighing about 13 to 20 pounds from trees and continue its flight without landing.
The Crowned Eagle
The African crowned is another large bird of prey worth mentioning for its weight-carrying capacity.
Although not as large as the martial eagle, it's considered Africa's most powerful eagle because of the weight of its prey.
The female adult crowned eagle weighs about 7 – 10 pounds, with the male considerably lesser at a weight of 5.5 – 9 pounds.
Its wingspan is between 59 – 71 inches, which is relatively short for its huge size.
It also has thick legs and long talons that it uses to crush the skulls of its prey and penetrate their brains.
Like most eagles of its size, the crowned eagle majorly feeds on:
- Mammals like monkeys
- Mongooses
- Feral cats
- Monitor lizards
- Snakes
- Rats
Some reports indicate that the crowned eagle can carry more than its body weight in flight.
Although these claims are not verified, they may be hypothetically true as remains of prey as large as 20 and 66 pounds have been found in its nest.
However, the crowned eagle mainly kills on the ground before tearing up the prey into pieces that it carries into its nest.
Chances are, it did the same with those large animals found in its nest.
Philippine Eagle
The Philippine eagle, as the name suggests, is endemic to the Philippines.
It is one of the largest birds in the world, considering its body length and wingspan, which measures 34 to 41 inches and 71 to 87 inches, respectively.
Despite being so massive at 8.9 to 17.6 pounds, the Philippine eagle is relatively fast and agile. It enjoys a diet consisting of:
- Monkeys
- Deer
- Flying lemurs
- Giant cloud rats
While there is no specific record of this bird's weight-carrying capacity, prey specimen found in its nest are in the 0.35 oz to 31-pound range.
Can a Bird Carry a Human Being?
So, you've seen how much different eagles can carry and are wondering if they can lift a human being. Well, the answer isn't so far away.
A bird can't carry an adult human being because the average human being weighs 136 pounds, which is nine times greater than the highest weight of 15 pounds recorded for a flying bird.
In theory, it would take nine bald eagles to lift an adult human being.
Although an eagle may lift a dog or cat as they weigh considerably less, it may find it challenging to carry them directly from the ground.
This is because a bird's load-carrying capacity depends on factors like its flight speed and wing size.
The faster the bird is swooping down toward its prey, the greater its lift potential.
The amount of load a bird can lift also depends on how it carries the said load. A bird can lift more if it's taking the load on its back than if it's holding it in its talons.
