The Solitary Sandpiper (Tringa solitaria) is a species of wading bird that breeds in the woodlands across much of Alaska and Canada. It is migratory and winters in Central and South America. It is very common in the Amazon River basin, and the Caribbean. It rarely is seen in western Europe. Its only relative in the Tringa genus is the similar Green Sandpiper.
This bird has a dark green back, grayish head and breast and otherwise white underparts. In flight, it is unmistakable, with dark wings above and below, and a dark rump and tail center. The dark rump is what distinguishes this species from the similarly related Green Sandpiper. In flight, this bird also has a three-note whistle.
Though this bird is non-gregarious, it sometimes can be seen in small numbers around suitable feeding areas. It is a fresh water bird, and sometimes it can be seen in areas that are too restricted for other waders, which prefer clear, open waters. Its food source is small invertebrates, and sometimes small frogs, that are picked off the mud along the shores of ponds.
The Solitary Sandpiper nests in trees, unlike most other scolopacids. The female lays 3 to 5 eggs in abandoned nests in trees. The young birds are believed to drop to the ground on their own soon after hatching.
