Long-tailed tit
This species has been described as a tiny (at only 13–15 cm in length, including its 7–9 cm tail), round-bodied tit with a short, stubby bill and a very long, narrow tail. The sexes look the same and young birds undergo a complete moult to adult plumage before the first winter. The plumage is mainly black and white, with variable amounts of grey and pink. Vocalisations are a valuable aid to locating and identifying these birds. When in flocks they issue constant contact calls and are often heard before they are seen. They have three main calls, a single high pitched ‘pit’, a ‘triple trill’ eez-eez-eez, and a rattling ‘schnuur’.
