(Scolopacidae; † Green Sandpiper T. ochropus) Late Med. L. tringa name given to the Green Sandpiper by Aldrovandus 1599  < Gr. τρυγγας trungas thrush-sized, white-rumped wading bird that bobs its tail, mentioned by Aristotle, not further identified, but taken by later authors to be a sandpiper, wagtail, or dipper; "78. TRINGA.  Rostrum teretiusculum, longitudine capitis.  Pedes tetradactyli: postico uniarticulato a terra elevato." (Linnaeus 1758); "Tringa Linné, Syst. Nat., ed. 10, 1, 1758, p. 148.  Type, by tautonymy, Tringa ocrophus Linné (Tringa, prebinomial specific name in synonymy)." (Peters, 1934, II, p. 264).  Linnaeus's Tringa comprised thirteen species (T. Pugnax, T. Vanellus, T. Gambetta, T. Interpres, T. tobata, T. Fulicaria, T. alpina, T. Ocrophus, T. Hypoleucos, T. Canutus, T. Glareola, T. littorea, T. Squatarola).
