Sound Detections

Forty one acoustic encounters

Seven observers among the twelve who visited the site for at least 48 hours between May 2005 and April 2006 heard either double knocks or kent calls, and observers detected these signature sounds of ivorybills on 41 separate occasions during this period including as many as 50 kent calls and 45 double knocks during single encounters.  Kent calls or double knocks were heard in May and December 2005 and January, February, March, April, May, June, and July 2006.
