Which tree species are frequently cited as prime targets for Yellow-bellied Sapsuckers in their northern breeding range?
Answer
Aspen and Birch
Habitat selection for the Yellow-bellied Sapsucker is closely tied to tree anatomy suitable for sap access. In the northern breeding zones, certain deciduous trees are preferred. Aspen and Birch are specifically noted as frequently cited prime targets in these areas, likely due to the ease with which their bark can be drilled and the characteristics of their sap flow during the warmer months when breeding occurs.
