I'm retracting my previous post, and replacing it with:
There's a shorebird at the Montlake Fill, and I'm reasonably sure it's not
a Kildeer.

I went back to the Fill, this afternoon, armed with a little more
knowledge, but left with no more certainty than before.

On the first visit, there were 2 birds with yellow legs. At least one was
extremely flighty, and making noise. I don't recall it being distinctly
two-noted, and it and its buddy flew off towards the open water. Later, I
saw a lone yellow-legged bird, quietly feeding at the northern end of the
big pond, where I first saw the yellow-legged pair. I assumed it was one
of the previous pair, but it might have been a different bird. I got a
reasonably good look at it, considering it was rainy.

On the second visit this afternoon, the cooperative bird at the north end
of the pond was still there. The flighty, noisy bird(s) was absent. It
was no longer raining, so I got a good, long look. The bird never called.
It looked about Kildeer size, but the Kildeers were absent from the Fill,
so the size estimate might be wrong. The bill looked straight, but longer
than the head. The "knees" might have been knobby; that was a toss-up.
Without rain, the bird looked more chocolate brown than gray on the back,
especially toward the lower parts of the wings. The back was speckled, but
not as speckled as the Greater Yellowlegs photo on page 152 in Paulson.
It did a lot of jerking its head backwards and up when alarmed, but did
not fly away from the north end of the pond.

So, there's either a Greater or a Lesser Yellowlegs at the Fill. Someone
else will have to make the definitive call.
