Yellow-bellied Sapsucker
Sphyrapicus varius
Neat rows of holes circle a tree trunk, marking a sapsucker’s feeding place. The bird may return repeatedly, taking sap and insects from wells it has opened in living bark.
When to Notice
Late fall–winter (October–March) for widespread visitors; some birds breed locally in higher mountain forests.
Where to Look
Look in deciduous and mixed woods, wooded edges, and parks with mature trees. Fresh wells on a living trunk may be easier to find than the bird- watch from a distance for a returning sapsucker.
WHAT MAKES IT UNIQUE
ROWS OF SAP WELLS
Small holes or rectangular wells are often arranged in repeated rows on living trees.
WHITE WING PATCH
A long white patch lies along the folded wing against darker plumage.
BOLD FACE STRIPES
Black and white stripes frame the face, with red on the crown of adults.
THROAT COLOR
Adult males have a red throat; adult females have a white throat. Young birds are less boldly marked.

Its place in the Blue Ridge
A Feeding Place Others Can Use
Sapsuckers open wells in living trees, including maples and birches, to reach sap. They also eat insects drawn to or caught around those feeding places. Hummingbirds and other animals can use the exposed sap. A maintained row of wells creates a small food source that would otherwise remain beneath the bark.
Different Needs Within One Tree
Living trees supply sap, while softened or decayed wood can provide places to excavate nest cavities. Sapsuckers therefore use trees in more than one condition and for more than one purpose. A wooded patch with a variety of ages and stages of decay offers feeding trunks alongside possible nest sites. Old wells remain as visible signs after a bird’s seasonal visit ends.
The Blue Ridge offers a southern foothold for a bird more closely associated with northern forests. Yellow-bellied sapsuckers visit widely in winter, while scattered breeding populations occupy higher mountain woodlands. Protecting these forests helps the species continue nesting near the southern edge of its breeding range.
A small wonder
Sap wells are tended feeding sites. A bird may return and renew the openings rather than simply drill once and leave. The repeated rows on a trunk can record visits made over time, with fresh and weathered marks side by side.
Notice for yourself
Compare two rows of wells on a tree visible from the path. Look for differences in the bark edges, dark staining, or fresh sap. Then wait quietly at a distance to see whether a bird returns, without touching or enlarging the openings.
