The ring-ousel, Turdus torquatus, has a dark bill and conspicuous white gorget, whence its name.
On the upper verge of the pine forests, or in the scrubby vegetation just beyond, the following are not uncommon - black woodpecker (Picus martius), ring-ousel (Turdus torquatus), Bonelli's warbler (Phylloscopus Bonellii), crested tit (Parus cristatus), citril finch (Citrinella alpina), siskin (Chrysomitris spinus), crossbill (Loxia curvirostra), nutcracker (Nucifraga caryocatactes), blackcock (Tetrao tetrix), and the alpine varieties of the marsh-tit (Parus palustris, borealis) and tree-creeper (Certhia familiaris, costae).
Thrushes have not been widely introduced, but the song-thrush and blackbird (Turdus musicus and Merula merula) are common in New Zealand; attempts were made, but unsuccessfully, to establish the latter in the United States.
The Latin proverb has it that "Turdus malum sibi cacat"; but the sowing is really effected by the bird wiping its beak, to which the seeds adhere, against the bark of the tree on which it has alighted.
This at least is not the Turdus migratorius.
