Clearly, given the background, that is a Sandpiper of Mordor.
That is a very dark photo of a bird.
I did see the crested caracara last week. Those people who saw it out hunting got killer views. It did not hunt while I was there, and I saw a part bird buried in a fir tree away from the attentions of the corvids.
It's weird. I comes up a little underexposed on my monitor at home, but not like this. I do have a correctly exposed shot, but only of the back half of the bird, as it walked out of shot. When seen on a different monitor, it's a terek sandpiper.
Well done on the caracara
A sandpiper that is very easily recognisable because of the bill - we need more of those! Except I wouldn't have recognised it from your photo because I was expecting a bigger bird. You've caught it with its neck outstretched and I just wasn't even thinking of a small peep. My brain was interpreting yellowlegs size.
For a peep it does have rather a long neck. And it's to the larger end of peeps: it has almost the same size range as lesser yellowlegs, according to my field guide.
