''Tringa'' is a genus of waders, containing the shanks and tattlers. They are mainly freshwater birds, often with brightly coloured legs as reflected in the English names of six species, as well as the specific names of two of these and the green sandpiper. They are typically associated with northern hemisphere temperate regions for breeding. Some of this group — notably the green sandpiper — nest in trees, using the old nests of other birds, usually thrushes. The willet and the tattlers have been found to belong in ''Tringa''; these genus changes were formally adopted by the American Ornithologists' Union in 2006.〔Pereira & Baker (2005), Banks ''et al.'' (2006)〕 The present genus in the old, more limited sense was even further subdivided into ''Tringa'' proper and ''Totanus'', either as subgenera or as full genera. The available DNA sequence data suggests however that neither of these is monophyletic and that the latter simply lumps together a number of more of less closely related apomorphic species. Therefore it seems unwarranted to recognize ''Totanus'' even as a subgenus for the time being.〔Ballmann (1969), Pereira & Baker (2005)〕 ==Living species== These are listed in systematic sequence: * Green sandpiper, ''Tringa ochropus'' * Solitary sandpiper, ''Tringa solitaria'' * Grey-tailed tattler, ''Tringa brevipes'' - formerly ''Heteroscelus brevipes'' * Wandering tattler, ''Tringa incana'' - formerly ''Heteroscelus incanus'' * Spotted redshank, ''Tringa erythropus'' * Greater yellowlegs, ''Tringa melanoleuca'' * Common greenshank, ''Tringa nebularia'' * Willet, ''Tringa semipalmata'' - formerly ''Catoptrophorus semipalmatus'' * Lesser yellowlegs, ''Tringa flavipes'' * Nordmann's greenshank, ''Tringa guttifer'' * Marsh sandpiper, ''Tringa stagnatilis'' * Common redshank, ''Tringa totanus'' * Wood sandpiper, ''Tringa glareola'' File:Spotted Redshank (Tringa erythropus) at Bharatpur I IMG 5552.jpg|''Tringa'' legs are either red (spotted redshank, ''T. erythropus''), ...
