     […] The flesh [of the mistletoe berry] is sticky, and forms strings and ribbons between my thumb and forefinger. For the mistletoe, this viscous goop – and by the way, viscous comes to English from viscum – is crucial. The stickiness means that, after eating the berries, birds often regurgitate the seeds and then wipe their bills on twigs – leading to the seeds' getting glued to the tree, where they can germinate and begin the cycle anew.
