Searching for Bonnie

After three years of searching in the Big Cypress National Preserve we have found a roost of the Florida Bonneted Bat (Eumops floridanus). Our acoustic monitors lead us to an old woodpecker tree at Raccoon Point. On two occasions we peeped the cavities in this tree but did not see any bats. Because the accoustic monitors kept leading us back to this tree and bat guano was found at the base of the tree we decided to stake it out at emergence time.  Last night, 27 minutes after sunset the first bat emerged.  Over the next hour, ten more bats followed. Their size and recorded calls confirmed that they are Bonneted bats.
