Join Dave Leatherman, Master of Forestry, Duke University, for a free lecture Sept. 21 titled "Our Feathered Service Providers."

Leatherman will explore the ecological services provided by Boulder-area birds, including the pollination of plants, regulation of other organisms often labeled by human society as "pests", distribution of plant seeds and even how they inspire music and other art forms. Mingled throughout will be tips on how to encourage birds in our yards and public lands.

Thursday, Sept. 21, 7 p.m.
Hale Science, room 270
