Ivory-billed Woodpeckers

In 2005, students and I discovered and documented a small number of Ivory-billed Woodpeckers in Florida. We made many recordings of double knocks and kent calls and documented more than 20 sightings but we failed to get a clear photo or video of the birds.  

A full account of the search can be read in my book "Ivorybill Hunters" published by Oxford Press.
