You have to take pity on the woodpecker family of birds. This is the second time I’ve run across a woodpecker with a name that doesn’t describe the bird.
These birds are seen around here. You can hear them tapping holes in trees and they do suck sap.
All of the pictures are from Wikimedia Commons.
On tree that the Yellow Bellied Sapsucker likes is the Birch Tree.
