What people are saying

"The Invisible Mammal" does an impressive job of driving home the urgent need to save as many bats as possible, while we still can.

Rae Alexandra

KQED

"The Invisible Mammal" can best be described as a highly entertaining stereotype-buster.

Peter Wong

Beyond Chron

Certainly, it will be hard to look at these "rats with wings" s budding Nosferatus ever again after watching a scientist bottle-feed an orphan. Prepare to be ahh-ed.

Pam Grady

San Francisco Chronicle

It all flows as beautifully as a murmuration of bats!
