MOST DETAILED RESPONSE:  This is a woodpecker of the Ladder-backed variety. More specifically a Yellow-Bellied Sapsucker. There are very few woodpeckers that have the distinctive red patch on both their crown AND under the chin/neck area. Also the longitudinal wing stripe is characteristic to the sapsucker family.
ADDED INFO:  It’s a Yellow-bellied Sapsucker. My book states the male is the only Missouri woodpecker with a red chin patch.

Pileated Woodpecker
