Woodpecker

Nothing could be more like a woodland construction worker than the drilling sound of a bark busting, burrowing little birdie. So unlike the noises made by other industrious animals, the unique staccato sound must seem so strange to the rest of the feathered forest dwellers. Not a high pitched call or a rustling of the leaves. This bird doesn't go about whistling and wandering, gathering his nest from the garbage on the ground, he hammers out his house from the trunk of a living tree! There are about 200 species in the Woodpecker family. Many are threatened or endangered due to loss of habitat or habitat fragmentation. Two species, the Ivory-billed Woodpecker and the Imperial Woodpecker, have been considered extinct for about 30 years. Woodpecker bills are typically longer, sharper and stronger than the bills of other similar birds. Many of the foraging, breeding and signaling behaviors of woodpeckers involve drumming and hammering using the bill. To prevent brain damage from the rapid and repeated knocking, woodpeckers have evolved a number of physical adaptations.
