Solitary Sandpiper is a boreal shorebird familiar to many in the Neotropics.  Breeding across the boreal forest of Canada and Alaska, the species is found throughout Central and South America south to the central Southern Cone during the boreal winter.  This small Tringa is often found along the edges of protected freshwater pools and rivers, where it feeds along the shore while bobbing its rear end.  Frequently detected in overflight, Solitary Sandpipers give away their presence with high, piercing pseeeee-pseeee calls.  It is small, dark gray-brown above with small white spots, white spectacles, white underparts, and a white tail with brown barring and dark central tail feathers.  Typically, the species is found in relative isolation from large flocks of other shorebird species.
