"The Feather Wars" Meet Author James H. McCommons
Oskaloosa, IA
May 11, 2026
6:30 pm
We’re excited to announce that Book Vault & Mahaska County Conservation are partnering to bring author James H. McCommons to Mahaska County on from 6:30-7:30 pm on May 11th at the Environmental Learning Center.
McCommons is the author of the newly released “The Feather Wars”. When food, fashion, market forces, and even scientific inquiry demanded the deaths of birds, a colorful cast of turn-of-the-century Americans rose up in protest. James H. McCommons’ insightful history chronicles battles for bird protection in every corner of the country, waged with words and images and sometimes with guns. The Feather Wars is a reminder of the power of grassroots conservation and a plea to continue the fight.”—Melissa L. Sevigny, author of Brave the Wild River.
The list of characters of this conservation movement includes Oskaloosan John F. Lacey, William T. Hornaday & Ding Darling. Books are available now at Book Vault and will be available at the event.
Registrations are not needed. The event will be held in the lower level of the ELC. Parking and entrance are on the south side of the building. Doors will open early at 6 pm. The Environmental Learning Center is located at 2342 Hwy. 92, Oskaloosa, IA 52577.
