We all love David Sibley for how much his books have helped us with bird identification. Now, with a simple experiment he and his kids conducted at home, he may have single-handedly done more to protect birds than any of the rest of us will do in our lifetimes. Granted, we'll have to see if his method pans out after more testing. But if the Sibley method turns out to really work, we'll all be singing his praises for many years to come.
