Forget manicuring your lawn this fall. Endangered birds need messy yards to survive the winter.
There are a billion fewer birds in North America than there were 40 years ago, and a fifth of the bird species on the continent are listed as “vulnerable” to population collapse over the next few decades.
You can help many of them survive the winter by putting down the garden tools and going easy on yard work this fall, the Audubon Society says.
