The second nature book in a series developed by Yarmouth-based Islandport Press and Maine Audubon will get its official release on Saturday at Gilsland Farm in Falmouth. “A Little Brown Bat Story” follows “A Snowy Owl Story,” released in February. Both were written by Melissa Kim. A third book, on turtles, is scheduled to come out next year.

The event, on the farm’s Apple Day, is scheduled to be held from 10 a.m. to 2 p.m. and will include readings from the book by Kim and illustrator Jada Fitch. Both will sign books as well and a live bat will be on hand. It’s free for Audubon members and $7 for others. Children under 2 are free. For more information go to Maineaudubon.org.

“A Little Brown Bat Story” is the story of a bat who must find a safe place to spend the winter and avoid a fungus threatening bats in the United States and Canada.

The goal of the book series is to bring stories about wildlife, conservation and “respectful human interaction” to pre-K through second-grade readers, according to a news release from Islandport Press. For more information on the book go to Islandportpress.com.
