Which group of tree species are commonly noted targets for Yellow-bellied Sapsuckers due to reliable sap flow?
Answer
Maples, birches, cherries, elms, pines, and spruces.
Yellow-bellied Sapsuckers display flexibility, having been documented feeding on the sap of over fifty different tree species, indicating they are not excessively selective. However, ornithologists observe distinct preferences driven by the sweetness and consistency of the sap flow. Specific species are frequently targeted across various geographies. These commonly preferred sources include deciduous trees known for rich sap, such as maples and birches, alongside certain conifers like pines and spruces. Cherries and elms are also often included in the list of favored trees tapped by these specialized feeders.
