Pileated Woodpecker

Dryocopus pileatus

'Pileated' means 'wearing a cap,' for its flaming red crest, on a woodpecker the size of a crow.

Dryocopus is Greek for 'tree-beater'; pileatus is Latin for 'capped' (from pileus, a felt hat). In ancient Rome, the pileus was the felt cap given to freed slaves.
