Research Interests

Ecological Studies
Laurie Eberhardt studies the behavior and ecology of woodpeckers, especially sap feeding behavior. Sap feeding poses intriguing problems because the birds must overcome a tree's defenses and also may experience nutritional limitations to feed on sap. Recent student projects in her lab group have included studies on tree species preference, variations in sucrose content and flow rate of sap, changes in sap feeding behavior with weather conditions, and microscopic examination of sap hole structure.
