treecreeper (English)

Where does "treecreeper" come from?

The name treecreeper is a straightforward compound of two Germanic words: 'tree' and 'creeper.' 'Tree' traces back to the Proto-Indo-European *dóru, which carried connotations of strength and firmness, while 'creeper' originates from the Old English 'creopan,' meaning to crawl or move close to the ground. Together, they perfectly capture the behavior of these small birds, which spend their lives creeping along the trunks and branches of trees.
