Want to develop your bat identification skills? Interested in understanding bat sounds? This workshop includes a practical session by a river to practise your skills and enable you to take part in surveys for the National Bat Monitoring Programme (NBMP).

Organised by the Bat Conservation Trust, the course will equip particpants with species identification skills 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 cover heterodyne detectors, training your "sonic memory", and breaking bat sounds down into four elements: repetition rate, rhythm, tonal quality, and pitch. You will learn how and why these elements vary between different species, and how to find the "peak frequency" using a heterodyne detector.

The workshop starts indoors with a presentation, and moves outside at dusk travel to practise skills. 

The training will include an overview of the National Bat Monitoring Programme (NBMP), and participants will learn how to take part in the NBMP Field Survey.

Cost £16.
