Mistle thrush International Union for Conservation of Nature as being of least concern. The mistle thrush was first described by Linnaeus in his "Systema naturae" in 1758 under its current scientific names. "Turdus" is the Latin for "thrush", and "viscivorus", "mistletoe eater", comes from "viscum" "mistletoe" and "vorare", "to devour". The bird's liking for mistletoe berries is also indicated by its English name, "mistle" being an old name for the plant. There are more than 60 species of medium to large thrushes in the genus "Turdus", characterised by rounded heads, longish pointed wings, and usually melodious songs.

Mistletoe the host plant. "Viscum album" successfully parasitizes more than 200 tree and shrub species. All mistletoe species are hemiparasites, because they do perform at least a little photosynthesis for at least a short period of their life cycle. However, in some species its contribution is very nearly zero. For example, some species, such as "Viscum minimum", that parasitize succulents, commonly species of Cactaceae or Euphorbiaceae, grow largely within the host plant, with hardly more than the flower and fruit emerging. Once they have germinated and attached to the circulatory system of the host, their photosynthesis reduces so far that it
