Of all our woodpeckers, the Downy is the tich of the family while the Pileated is the giant (assuming the Ivory-billed and the Imperial woodpeckers remain extinct). The Downy is only 7" in length while the Pileated is almost 3 times as large at a massive 20".
The Pileated (pile-e-ated) instead is named for the prominent pointy tuft of red on its head -- resembling a Pileus (pile-e-us), or Roman felt cap, which it resembles.
Elsewhere in the Swamp, a wintering indigo bunting is found among the more numerous painteds.
