In 1953, ornithologist and educator Roger Tory Peterson and a friend took a 100-day trip around the United States to explore birds and the places they seek shelter. Peterson, known for his many birding guidebooks, recounted the trip in the book "Wild America."
Nearly 70 years later, retired journalists Anders and Beverly Gyllenhaal packed their lives into a 23-foot Airstream trailer and set out on a similar journey. They weren't taking an ordinary birding trip. Instead, they wanted to report on the how changes in us and our country have affected birds.

The country they traveled would have twice as many people and billions fewer birds than the one Peterson explored. Their journey also resulted in a book, "A Wing and a Prayer: A Race to Save Our Vanishing Birds," (Simon & Schuster, $30). A plea to help echoes through every page.
One of their first stops was to visit with John Fitzpatrick, director emeritus of the Cornell Lab of Ornithology, whom the Gyllenhaals call "the hemisphere's most influential voice on behalf of birds."
"They — the birds — are telling us that we need to look carefully at what's going on," Fitzpatrick tells them.
What the Gyllenhaals find as they continue their exploration renders Fitzpatrick's comment gentle understatement.
Bird conservation is not rocket science, Fitzpatrick told the authors. "It's more complicated than that."
In 2019, a group of researchers found a way to calculate North America's total bird population. The report, published in the journal Science, showed a loss in the past 50 years of 3 billion birds, nearly a third of the continent's bird population.
