The Bald Eagle

This is a comeback story. A story fuelled by the indomitable spirit of one individual.

In the Rocky Mountains, seeing a bald eagle is now relatively common. But that wasn’t always the case.

Once threatened in the lower 48 United States because of poisoning from the use of the now banned pesticide DDT, the population was reduced to just over 400 breeding pairs. The bald eagle’s best hope, in America at least, was widely believed to be the population in and around the world’s oldest national park: Yellowstone.

And it was here, in 1982, that one remarkable, female eagle was born.

 

Like many unsung heroes, her story went unnoticed for decades. She hatched, fledged and took to the skies to carve out her life.

She did the usual bald eagle things. At five, she started to breed and raise her own chicks. She survived and thrived – helped her young survive and thrive – thanks to the eagle’s evolutionary superpower: sight.

With both monocular and binocular vision, they can use each eye on their own to search for prey, or both together, like people. Pretty cool, but not as cool as this: eagles also have two focal points – one that looks straight ahead and the other that SIMULTANEOUSLY looks to the side. You know, so they can steer clear of mountains, while not taking their eye off that kill almost five kilometres away.

Wait, what?

Yes, almost five kilometres away, an eagle can spot its prey in technicolour – seeing more colour than you or me – and UV wavelengths, helpful in picking up, say, blood trails of animals wounded by mammal – two or four legged.

Anyway,

back to the story.

Our eagle’s journey of survival and reproduction was abruptly halted when she was hit by a vehicle. But her story didn’t end. She was rescued, rehabilitated and re-released into the wild, but not before her importance to her species was understood.

This eagle? She was 34 years old –the third oldest recorded wild bald eagle. During her life, she raised anywhere from 29 to an astounding 87 chicks to adulthood – many of whom would go on to reproduce and contribute to an increasingly healthy gene pool of eagles on both sides of the border.

Think about it. One eagle in one ecosystem, at a dire time, played a massive role in bringing back an iconic species from the brink. The power of one, helped along with a little help from her friends.

So look up and if you see an eagle soaring in the sky, don’t just think of it as beautiful or the symbol of one of eight countries and numerous Indigenous nations, wonder about its story and what that eagle might be doing, unheralded, in the ecosystem where you live.
