A harpy eagle, one of two birds David Anderson is currently studying through his work at the Peregrine Fund. Anderson is an ornithologist there in addition to climbing trees whenever he can.

Since my friends and relatives know I follow eagles (literally and figuratively!), they'll send me things that they think will interest me related to eagles.  My cousin in Conn. just sent me the two attached pics, which of course made me have to look up info about them.  ;D

"Harpy Eagles are among the world's largest and most powerful eagles. Their rear talons are about 3-4 inches long ? the same size as a grizzly bear's claws!"

"The Philippine eagle, also known as the monkey-eating eagle or great Philippine eagle, is an eagle of the family Accipitridae endemic to forests in the Philippines."

This info made me curious as to which eagle was the biggest, and this is what I found:

The World's Largest Eagles:

Haast's Eagle, 300 cm (118 inches)
Steller's Sea Eagle, 250 cm (98.4 inches) ...
White-tailed Eagle, 244 cm (96 inches) ...
Australian Wedge-Tailed Eagle, 230 cm (7.55 inches) ...
Golden Eagle, 220 cm (7.23 inches) ...
Philippine Eagle, 220 cm (86.6 inches) ...
Harpy Eagle, 200 cm (78.7 inches) ...
Martial Eagle, 193 cm (75.8 inches) ...

I wondered why the bald eagle wasn't on the list, so I looked that up also:

"A sea eagle, it has two known subspecies and forms a species pair with the white-tailed eagle."

So if I'm understanding this correctly, the bald eagle would be up near the top of this list by Stellar's Sea Eagle and the White Tailed Eagle.

(Originally posted on the Flyway thread, but realized it should go somewhere else.)

Thanks, NW. The numbers you quoted are wingspans, which I learned from reading the article the figures came from: https://www.worldatlas.com/articles/the-largest-eagles-in-the-world.html. Wingspan isn't the primary measurement to consider when determining the "largest," because wingspan depends on the eagles' habitats. Well, everything depends on their habitats...

Before reading the source of the info, I was guessing Steller's as #1, maybe tied with Harpy and/or Philippine, and not considering Haast's at all.

That source says the Philippine eagle is the "largest and heaviest known eagle."  Haast's eagle is ranked #1 because it was the largest ever known, but is now extinct. It's a little hard to gauge the source's accuracy since they don't define what "large" means. But aren't they all spectacular?!

Thanks for that info T40!  I wonder why they still have an extinct eagle on the list?  And thanks for noting that those were the wingspans.  I was in a hurry with my boss in the office and only had time to post what I was able to.  I had seen a video on the Philippine eagle a while back and remembered that their diet consisted of monkeys.  Beautiful eagles.  And the Harpy eagle looks fearsome!
