NBMP Introductory Bat Detector Workshop, Wick, 25th May 2018
14th May 2018
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 Liz Ferrell.
Please see the workshop outline below.
