Black-Necked Stilt

Thank you. I think you have your ID now. Job done. How satisfactory. And lucky you being there.

Reading further in Wikipedia, I see "The Hawaiian Stilt is sometimes considered a subspecies of the Black-necked Stilt." And it seems to have more black on the neck. Thank you for this spotting. Very interesting.

Very curious. It should be a stilt, but the only stilt that should be there is the Black-necked Stilt (Himantopus mexicanus) which has a white breast and white down the front of the throat (see http://en.wikipedia.org/wiki/Black-necked_Stilt). Did you take any more photos? Could you see the bill? Was it long, straight and pointed? Perhaps the stance changes the appearance of the neck.
