The mistle thrush (Turdus viscivorus) is a bird common to much of Europe, Asia and North Africa. It is a year-round resident in much of its range, but northern and eastern populations migrate south for the winter, often in small flocks. It is a large thrush with pale grey-brown upperparts, a greyish-white chin and throat, and black spots on its pale yellow and off-white underparts. The sexes are similar in plumage, and its three subspecies show only minimal differences. The male has a loud, far-carrying song which is delivered even in wet and windy weather, earning the bird the old name of "stormcock".
Found in open woods, parks, hedges and cultivated land, the mistle thrush feeds on a wide variety of invertebrates, seeds and berries. Its preferred fruits including those of the mistletoe, holly and yew. Mistletoe is favoured where it is available, and this is reflected in the thrush's English and scientific names; the plant, a parasitic species, benefits from its seeds being excreted by the thrush onto branches where they can germinate. In winter, a mistle thrush will vigorously defend mistletoe clumps or a holly tree as a food reserve for when times are hard.
The open cup nest is built against a trunk or in a forked branch, and is fearlessly defended against potential predators, sometimes including humans or cats. The clutch, typically of three to five eggs, is incubated for 12–15 days, mainly by the female. The chicks fledge about 14–16 days after hatching. There are normally two broods. There was a large range expansion in the 18th and early 19th centuries, although there has been a small decline in recent decades, perhaps due to changes in agricultural practices. Given its high numbers and very large range, this thrush is classified by the International Union for Conservation of Nature as being of least concern.
Mistle thrushes are found as individuals or pairs for much of the year, although families forage together in late summer, and groups may merge to form flocks of several tens of birds; it is not uncommon for up to 50 thrushes to feed together at that time of year. They roost at night in trees or bushes, again typically as individuals or pairs, but with families roosting together in autumn.
The mistle thrush is quite terrestrial, hopping with its head held up and body erect; when excited, it will flick its wings and tail. The flight consists of undulating bounds interspersed with glides.
