Etymology: The treecreeper is about as transparent as English compounds get: it is simply "tree" joined to "creeper," a bird that creeps up trunks. "Creeper" comes from the verb "creep," and the noun has long been applied to plants and animals that move low along the ground or climb, such as the creeping vine. Put the two together and the name describes the bird's whole method of feeding, spiralling upward and probing bark for insects. The first element traces back a long way. "Tree" descends from an ancient Indo-European root meaning something like "wood" or "timber," passing through Proto-Germanic and Old English "trēow" before becoming the modern form. The word has kept its core sense of a woody plant across all those stages, which is unusual for a term so central to everyday speech.

Synonyms: certhiid, small bird, woodland bird
