In this close up view of bayberries you can clearly see a whitish waxy coating. Bayberries are boiled to melt this wax for use in bayberry scented candles. One of the berries has been nibbled by a herbivore, most likely a insect. You can see from the nibbled surface how the wax forms a layer across the surface. Clearly the berry was distasteful to the (presumed) insect that was eating it as only a small portion of a small berry was devoured. Yellow-rumped Wablers swallow the berries whole and are then able to extract nutrition from them while distributing the seeds of the plant.

Educational Language
Pedagogical Use Description This image can be used in lectures dealing with behavioral and evolutionary biology. To introduce concepts of evolution and competition, this image can be used to illustrate the warblers' dependence on insects for their diet and survival. The discussion can proceed to mention the yellow-rumped warbler's special adaptation allowing this species to eat bayberries to avoid competition among other warbler species. This image can also be used in courses that take field trips in native habitats of the warblers.
