Which bird species causes bird peck in walnut trees to access sap?

• A. Red-bellied woodpecker.
• B. Yellow-bellied sapsucker.
• C. Pileated woodpecker.
• D. Black-capped chickadee.

Answer: (B)

Sap-feeding by drilling sap wells in trees is a behavior most strongly associated with sapsuckers. The yellow-bellied sapsucker is the bird that routinely makes lined rows of small holes to access sap, and sometimes the insects drawn to those wells. This pattern of sap wells is a telltale sign of this species' feeding strategy, and it explains why you’d see sap being tapped in walnut trees. The red-bellied woodpecker and the pileated woodpecker focus mainly on insects within wood, not on sap wells, while the black-capped chickadee doesn’t create sap wells and instead forages for insects and seeds in different ways.
