Authors Michael Forsberg (On Ancient Wings) and Paul A. Johnsgard (eight titles with UNP, including Crane Music) are featured in the documentary Crane Song.

From Forsberg’s webpage on the documentary: "Crane Song weaves together striking visuals and majestic sounds of the birds’ journey with the stories and
insights of the individuals who observe these creatures, as well as landowners endeavoring to ensure a habitat that is welcoming to the cranes."

Crane Song aired on PBS Nebraska station NET on March 18, March 19, March 24, and March 25.  If you missed it, you can purchase the DVD on NET’s website.  You can also watch a promo below.
