Recorded with two spaced Primo EM 272 omnidirectional microphones, April 2021
Spectrogram of a creaky tree, recorded at Strumpshaw Fen March 2020. Using a contact and two Sennheiser ME64 cardioid microphones.
A Roesel's bush-cricket. The sound was recorded in the grass of the adjacent sand bank sea defence. The call is at around 20KHz so the pitch is lowered to within audible range. Terns can also heard in the background.
The sound of a bat - echolocating along the Lincolnshire coastal path. There is also an insect possibly a cricket or dune chafer? The pitch of the bat call is lowered and layered onto the original recording.
