The scarcity of natural tree cavities prevents many birds from nesting.

But if properly constructed and installed, man-made nest boxes and other nest structures can serve as good substitutes and help increase the population of more than 25 East Tennessee bird species.

Join instructor Marcia Davis for a new non-credit course called All About Birdhouses (Saturday, February 27, from 9 a.m. to noon).

The course fee is $39; online registration is available.

She will discuss habitat requirements, nest box specifications, features of a well-designed nest box, and maintenance, monitoring, and predator protection.

Davis, who has a master’s degree in biology, is author of the “Birdlife” column in the Knoxville News Sentinel.
