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.

Herbivore adaptations to plant defense Protease inactivation can lead to many issues such as reduced feeding, prolonged larval development time, and weight gain. However, many insects, including "S. exigua" and "L. decemlineatu" have been selected for mechanisms to avoid the effects of protease inhibitors. Some of these mechanisms include developing protease enzymes that are unaffected by the plant protease inhibitors, gaining the ability to degrade protease inhibitors, and acquiring mutations that allow the digesting of plant tissue without its destructive effects. Herbivores may also produce salivary enzymes that reduce the degree of defense generated by a host plant. The enzyme glucose oxidase, a component of
