Woodpeckers are best known as the family that chisel into tree trunks with their beaks. Most species eat insects that they prise out of wood with their beaks and tongue, but the sapsucker consumes tree sap. Wrynecks are also in this group and spend most of their time on the ground feeding on ants.
Scientific name: Picidae
