Calidris minuta
A small compact wader with dark legs and short, almost straight dark bill. Noticeably smaller than Dunlin, and with shorter, and straighter bill. Similar in size to Temminck's Stint, but legs dark, tail shorter (and grey) and markings on back less plain. Juveniles with prominent white V on back, and split white supercilium. Upperparts of adults rufous brown in summer, and light grey in winter.
Contact call a quite soft, short, high pitched "pit". Sometimes uttered in series, or as soft chattering. Song a cyclic series of thin "peee-peee-peee" rising and falling in pitch.
