Query: Waders of the Lost Ark

This book is poignant and RIVETING. The protagonist is as "muck"rakingly mortal as a Ross Macdonald sleuth and the Delta-country bit parts have the idiosyncrasies of Dashiell Hammett collaborating suspects. The woodpecker himself, whether guilty of existing of not, is as elusive and infuriatingly (intentionally?) mysterious as a John le Carre double agent. And the stakes, a second chance for all of us, to find and preserve the "Lord God bird" are so heartbreakingly high as to be virtually Biblical.
