Genus TRINGA

Bill slender, flexible, varying in length, straight or slightly curved downwards, both mandibles grooved ; nostril small, near the base of the mandible. Wing long, pointed, 1st quill longest, tertiaries nearly as long as primaries; tail nearly square, the median rectrices pointed and projecting slightly in some species. Tarsus rather short, scutulated ; hind toe present; anterior toes divided to the base, not webbed.

This genus comprises the Stints, which are distinguished from the Sandpipers (Totanus) by having a softer, more flexible bill, and by the almost entire absence of any web between the anterior toes. The species, about 20 in number, are often distributed amongst a number of genera on account of slight differences in the length or form of the bill; but it is evident that all are closely allied, more so than the species here referred to Totanus. No less than 9 forms of Stint have been recorded from India, Ceylon, and Burma; all are migratory birds, breeding in Northern Asia, and the majority are found in India in flocks, feeding on worms, small Crustacea, and insects and their larvae, which are obtained either from sand or mud banks on the coast or in estuaries, or from marshy ground inland.
