Yellow-Bellied Sapsucker Tracks Wasp (2542)
A Yellow-bellied Sapsucker tracks the flight of a wasp with his eyes and prepares to dispatch it with his bill. Sapsuckers drill a pattern of holes in trees that fill with sap. These sap wells are magnets for insects, mammals, and birds, and serve as a primary food for hummingbirds migrating north in the spring.
