Never Arm Wrestle a Bald Eagle

A Raptor’s Talons Have Fierce Gripping Power


Reading Time: 3 minutes

I’m smart enough to know I should never shake hands with a Bald Eagle because their talons have a killer grip.

I saw their fierce grip on display this week, playing out in the sky several hundred feet above me.

I’m not far from the Hudson River near the Kingston-Rhinecliff Bridge in Kingston, New York, and a bird with a massive wingspan catches my eye.

I see the white head and tail, and my mouth drops, as most people do when seeing Bald Eagles in the wild.

The bird’s rapid wingbeats indicate the eagle is powering to its destination, carrying a red squirrel in both its talons.

Probably a feast for its hungry eaglets.

My Talons are Fiercer Than Yours

While I’m enjoying the sight of this beautiful raptor, I see another large bird coming into view.

This time it’s a Red-tailed Hawk dive-bombing toward the eagle.

Now I’m watching this epic struggle play out above me.

Suddenly the hawk attacks the eagle in an attempt to grab its dinner, and the eagle lets go of the squirrel in its left talon while keeping a firm grip of it in its right talon.

Then with its left leg free, the eagle uses it as a weapon striking the hawk and pushing it from its path.

One powerful push and the hawk was on course.

The hawk circles back for a second attempt, but never gets into an aggressive position to grab the squirrel.

The Bald Eagle emerges triumphant and powers on with his squirrel feast.

Fierce Gripping Power of an Eagle’s Talons

And it got me thinking about the fierce gripping power of a raptor’s talons.

A raptor’s feet are incredible hunting tools.

The word raptor comes from the Latin word “rapere,” which means to seize by force.

Eagle and hawks both have two giant talons on their first and seconds toes, giving them a secure grip on their prey.

Prey that they like to eat alive.

The power of an eagle’s grip comes from its leg muscles, tendons, and bones.

When an eagle contracts the tendons on its legs, the muscles close the bird’s talons.

The tendons are contained in tendon sheaths, and both the tendons and tendon sheaths have tiny ridges.

When an eagle’s tendon contracts, ridges on the tendon and sheaths interlock, creating a “ratchet” effect enabling the bird to keep its talons closed over long periods while subduing large prey.

So an eagles grip is to be feared.

Raptor with the Strongest Grip

According to scientists at HawkQuest, an environmental education nonprofit in Colorado, a Bald Eagles gripping strength is ten times stronger than the average grip of an adult human hand.

A Bald Eagle can exert upwards of 400 pounds per square inch (psi).

Googling a raptor’s gripping strength, I find unscientific research focusing on five bird species with the strongest talon crush rates, and it includes some of the fiercest raptors in the world.

The data indicate psi gripping strength varies among raptors, but the number is the average from several references.

These numbers are not scientifically proven, but help illustrate a point about the power of a Bald Eagle’s grip.

Great Horned Owls have a 500 psi.

Philippine Eagles have a psi higher than 500.

Harpy Eagles have a 598 psi.

Gold Eagles have a 791 psi.

Bald Eagles have an 823 psi.

Never try arm wrestling a Bald Eagle. You'll lose!

Conclusion: Never Arm Wrestle a Bald Eagle

So in the bird world, the hawk I mentioned earlier is not prying the squirrel from the Bald Eagle’s powerful clutches.

The eagle is not letting go of that squirrel until it is ready to let go.

It was fabulous seeing the natural world play out above me and using it as the inspiration to learning more about the gruesome power of a Bald Eagle’s talons.

Just another reason to marvel at these majestic birds when you see them in the wild and to value and protect Bald Eagles and other wildlife at all costs.

Project the birds, and you protect the earth! Let’s all coexist.
