Acoustic monitoring of birds

Acoustic monitoring using fixed Passive Acoustic Monitors (PAMs): building on work undertaken in 2022-23 we are installing additional fixed PAMs across the site. Ten of the PAMs will be placed along two transects (see below) which will enable direct comparison of different survey methods. PAMs are set to record between 1 hour before dawn to 3 hours after dawn and for 1 hour either side of dusk – all species of bird breeding at the site are likely to be vocally active during these time periods. Data from the PAMs will be sent to Wilder Sensing for identification with some validation and analysis of results undertaken by our own professional bird surveyor.
