Frog Whispering (kind of!!!!)

Identifying local frogs by their calls is easy once you learn the calls. Making frogs call on command (sometimes!!!) takes some trickery. A male Blanchard's cricket frog (Acris blanchardi) makes a series of rapid clicks that sound like "gick, gick, gick ..." Duplicating this call is easily done by clicking a toy or dog training clicker.

BioBlitz at the St Joseph County Park District

On Saturday June 9th at Spicer Lake Nature Preserve County Park near South Bend in St. Joseph County Indiana, Dr. Gary Merrill (Adjunct Curator (Bryology) in the Department of Botany), James Louderman (Collection Assistant in the Division of Insects) and Alan Resetar (Collection Manager in the Division of Amphibians and Reptiles) participated in the fourth BioBlitz sponsored by the St Joseph County Park District.  A population of the declining cricket frog (Acris crepitans) as well as many interesting bryophytes and insects were found.  A short sound clip from the bioblitz with a calling cricket frog making its characteristic clicking can be heard here (I attached a sound file).  We did not want to disturb the frogs so there is no cute frog footage - only cattails and calls.

Reptiles and Amphibians of Wolf Lake - Program - January 15, 2011

Alan’s projects center around the herpetofauna (amphibians and reptiles) of the Chicago area, particularly in the post-industrial landscape of the Calumet Region in northwest Indiana and southeastern Chicago. In cooperation with the National Park Service, U.S. EPA, Indiana Department of Natural Resources and The Nature Conservancy, he studies the distribution, ecology and conservation of this herpetofauna. In spite of large scale habitat disruption and destruction, there are still sizable remnants left of the patchwork of habitats that make the region unique.
