What secondary food source supplements the Yellow-bellied Sapsucker's diet besides the primary sugar from tree sap?
Answer
Insects that become trapped in the sticky, flowing sap.
Although tree sap provides the essential sugar foundation for the Yellow-bellied Sapsucker's year-round sustenance, its diet is not purely vegetarian. The process of drilling wells naturally creates a hazard for small arthropods. As the sap oozes out and becomes sticky, it acts as an unintentional trap, ensnaring various insects attracted to the sweet flow. The bird then consumes these trapped invertebrates, providing necessary animal protein. This secondary source of nutrition becomes particularly significant as the seasons progress, especially when the bird needs more diverse nutrients during demanding periods like the breeding season.
