The solitary sandpiper (Tringa solitaria) is a small shorebird. The genus name Tringa is the Neo-Latin name given to the green sandpiperbyAldrovandus in 1599 based on Ancient Greektrungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific solitariaisLatin for "solitary" from solus, "alone".[2]
This species measures 18–23 cm (7.1–9.1 in) long, with a wingspan up to 50 cm (20 in) and a body mass of 31–65 g (1.1–2.3 oz).[3][4] It is a dumpy wader with a dark green back, greyish head and breast and otherwise white underparts. It is obvious in flight, with wings dark above and below, and a dark rump and tail centre. The latter feature distinguishes it from the slightly larger and broader-winged, but otherwise very similar, green sandpiper (T. ochropus) of Europe and Asia, to which it is closely related.[5] The latter species has a brilliant white rump. In flight, the solitary sandpiper has a characteristic three-note whistle. They both have brown wings with little light dots, and a delicate but contrasting neck and chest pattern. In addition, both species nest in trees, unlike most other scolopacids.
As its name indicates, the solitary sandpiper is not a gregarious species, usually seen alone during migration, although sometimes small numbers congregate in suitable feeding areas. The solitary sandpiper is very much a bird of fresh water, and is often found in sites, such as ditches, too restricted for other waders, which tend to like a clear all-round view.
The sandpiper lays a clutch of 3–5 eggs in abandoned tree nests of songbird species, such as those of thrushes. The young birds are encouraged to drop to the ground soon after hatching.[6]
