NBMP Introductory Bat Detector Workshop, Margam Discovery Centre, Neath Port Talbot | Margam Discovery Centre | Saturday, 29. June 2019

This introductory bat detector workshop involves an evening classroom session followed by a practical field session starting around dusk. Bat sounds are broken down into four elements in order to train people's sonic memory and aid species identification using a heterodyne bat detector in the field. The focus is on pipistrelles, noctule, serotine and Daubenton's bat as these illustrate a range of different bat sounds. The workshop will be led by Diana Clark of Koru Ecology Associates.
Please see the workshop outline below.
