I have, over 20 years or so, seen 5 or 6 gulls, all Ring-billed I think, that I was
sure were one-legged.
However, in at least three of those cases I watched the bird in question, sometimes for up to 10-15 minutes and discovered that each in fact had two good legs but that for some reason had chosen to draw one up so high it was invisible. And I'm talking about hopping on the shore, taking off and landing and everything in between with one leg tucked into the belly.
Can't say that the others did not have a missing leg, or that yours didn't but to me the interesting question is "
Why do they do that?" as opposed to "
What happened to the other leg?" Either way - true pegleg or not - an interesting observation.

PS Do any of the expert birders have an answer to either question?
