The Solitary Sandpiper is the New World equivalent of the Green Sandpiper (Tringa ochropus).

Its non-breeding plumage is similar to its breeding plumage but a bit paler with the throat almost white and with smaller spots on the upperparts.

The Solitary Sandpiper nests in the forests of Canada and Alaska then migrates to South America starting in about July. See the distribution map at xeno-canto. They are the commonest shorebird in inland Brazil and, as their name suggests, they are seldom found in flocks.
