The seeds are coated with a sticky material called viscin.ost mistletoe seeds are spread by birds that eat the 'seeds' (in actuality drupes). Quite a range of birds feed on them, of which the mistle thrush is the best-known in Europe, the Phainopepla in southwestern North America, and Dicaeum of Asia and Australia.
