Active Audio Bat Surveys

For Summer 2018, Millersville University is involved in surveying bats in Lancaster County.  This survey effort is being led by Millersville Biology Student Carter Farmer.  The objective of the survey is to document the presence of rare bat species on Lancaster County Conservancy Properties. Surveys are conducted using specialized, sensitive microphones to record bat calls.  For bat species identification, the SonobatLIVE software program is used to illustrate patterns of recorded bat calls and uses maximum likelihood estimators to match recorded calls to those of known bat species.

Below are the results of an active audio survey conducted for bats on the Lancaster County Conservancy Climber’s Run Preserve.
