The long-tailed tit or long-tailed bushtit (Aegithalos caudatus), occasionally referred to as the silver-throated tit or silver-throated dasher, is a common bird found throughout Europe and Asia. The genus name Aegithalos was a term used by Aristotle for some European tits, including the 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’. The calls become faster and louder when the birds cross open ground or if an individual becomes separated from the group.
The long-tailed tit is globally widespread throughout temperate northern Europe and Asia, into boreal Scandinavia and south into the Mediterranean zone. It inhabits deciduous and mixed woodland with a well-developed shrub layer, favouring edge habitats. It can also be found in scrub, heathland with scattered trees, bushes and hedges, in farmland and riverine woodland, parks and gardens. The bird's year-round diet of insects and social foraging bias habitat choice in winter towards deciduous woodland, typically of oak, ash and locally sycamore species. For nesting, strong preference is shown towards scrub areas. The nest is often built in thorny bushes less than 3 metres above the ground.
The long-tailed tit is insectivorous throughout the year. It eats predominantly arthropods, preferring the eggs and larvae of moths and butterflies. Occasional vegetable matter is taken in the autumn.
The nest of the long-tailed tit is constructed from four materials - lichen, feathers, spider egg cocoons and moss, with over 6,000 pieces used for a typical nest. The nest is a flexible sac with a small, round entrance on top, suspended either low in a gorse or bramble bush or high up in the forks of tree branches. The structural stability of the nest is provided by a mesh of moss and spider silk.
