Many of the smaller species found in coastal habitats are often called "sandpipers". The smallest member of this group is the least sandpiper, small adults of which can weigh as little as 15.5 grams and measure just over 13 cm (5 inches). The largest species is believed to be the Far Eastern curlew, at about 63 cm (25 inches) and 860 grams (1.9 lb), although the beach thick-knee, is the heaviest at about 1 kg (2.2 lb).
