Having worked on various horseshoe crab projects in the Delaware Bay, I am familiar with this bird as it stops off en route from Argentina to fatten up on crab eggs...
Red Knot, Calidris canutus: dark legs, dark bill; breeding plumage is mottled grey on top ("scaley") with reddish face, throat and breast (not visible above) and light-coloured rear belly
