Abstract
While examining red-cockaded woodpecker (Picoides borealis) cavity contents in eastern Texas, the authors observed cavity tree resin avoidance by southern flying squirrels (Glaucomys volans). The tree surface around an active red-cockaded woodpecker cavity is coated with sticky resin which flows from resin wells created by the woodpecker. The southern flying squirrel is a competitor for red-cockaded woodpecker cavities and is known to be quire capable of entering active cavities in trees with a well developed resin coating. However, observation indicates that in some circumstances the resin coating can offer some deterrence
