Take a look at that image to the left. That is not a computer simulation or some mad taxidermist’s display. That is an actual photo of a herring gull sitting on top of a white-tailed eagle. I found it in the November 5 issue of New Scientist. It was taken by Markus Varesvuo. According to one commenter out there in the Internetsphere, the reason the eagle eye looks dead is because it has an inner eyelid that it is using to protect its eye.
Good idea because actually the gull is not sitting on the eagle, it’s attacking it. Apparently the gull is protecting its young. Here’s the interesting part: “Some gulls also defecate or even vomit on the predator for good measure.” Go daddy.
A quick search determined the location of this altercation to be Norway. Oddly, a further search on herring gulls gave me a bunch of pages indicating the range of the bird to be in North America. Even more freaky was that the herring gulls pictured on the webpages all have nice pink legs. Take a closer look at the gams on the gull in photo. Right. Yellow legs.
This was not making sense so I defaulted to Wikipedia. Aha! There’s an American herring gull and then there’s a European herring gull. Mystery solved: this is a European herring gull.
But not so fast. Wikipedia says European herring gulls have pink legs too. There is a species of gull that used to be a herring gull, but due to the vagaries of continuously updated taxonomy, is now considered a separate species. Guess what its name is? Right. Yellow-legged gull.
Do yourself a favor. Do not try and research this further. If you do, you will hurt yourself. You can see why with this sample from the Wikipedia entry:
“The Yellow-legged Gull (Larus michahellis), sometimes referred to as Western Yellow-legged Gull (to distinguish it from eastern populations of yellow-legged large white-headed gulls)… was formerly treated as a subspecies of either the Caspian Gull L. cachinnans, or more broadly as a subspecies of the Herring Gull L. argentatus. It is named after the German zoologist Karl Michahelles.”
Thank you Mr. Michahellas. Are we sure that it’s not really the gull formerly known as the yellow-legged large white-headed?
I don’t even dare to check out white-tailed eagles. I mean couldn’t that bird just as easily be a brown-feathered eagle with whitish tips on its tail. Or maybe the buff-headed, black-winged eagle that is distinguished from the yellow-beaked, brown-headed by the slight upturned tail and devious demeanor. Or something.
And you thought birds were boring.
