Just a few days after her publisher sent the final draft of her new book to the printer, Margaret Renkl saw the turtle. It was missing an eye, its shell was scarred — and it was cause for celebration.
Renkl, a weekly contributing columnist for the New York Times and bestselling author of "Late Migrations" and "Graceland, at Last," was delighted to spot the gnarled creature because she hadn't seen a wild box turtle in her suburban Nashville yard for more than two decades.
She'd lamented that fact in her latest book of essays out this month, "The Comfort of Crows: A Backyard Year." And then, that improbable reptile "amazingly" appeared after she had literally written off hope, said Renkl, who will be in St. Paul as part of the Talking Volumes series on Nov. 1.
The sense of delight in watching the creatures she loves even as she mourns those she misses fills the pages of "The Comfort of Crows." In the book, Renkl, a self-described backyard naturalist, chronicles Tennessee's seasons and her family's emptying nest over 52 weeks. She describes days of weather out of whack and ever fewer butterflies and birds.
Funny and vibrant, the book is by no means a downer, despite the fact that she writes of upended natural patterns and biodiversity loss.
"The book does occupy an uncomfortable sort of space," Renkl acknowledged. "I want to revel in the beauty and the joy of the world, but I want to be very conscious of how imperiled that beauty really is."

She knows, though, that getting people to care, truly care, is a more likely path to action.
"I hope that readers might fall in love with the things I love, because I have this really strong sense that people save what they love," she said. "So if it means that somebody reads this and notices the birds or the insects or other crawly critters in their own yard, and then thinks, 'How can I help?' That would be my real hope. If you think, 'How can I help?' then the world opens to you."
