Bioacoustics

• Animals can be elusive

– In particular birds, bats, insects

• Better detected by their sound

• Better classified by their sound (speciation)

Example

• iBats – Bat mobile

The New Forest Cicada

• Native to the UK

• Only in the New Forest

• Call at ~13.5 kHz

• Most people >40 can’t hear it

• Those who can, hear it even 60m away
