The green sandpiper (Tringa ochropus) is a small wader (shorebird) of the Old World. The genus name Tringa is the New Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific ochropus is from Ancient Greek okhros, "ochre", and pous, "foot".
