Remarks from the Recordist

Recorded with my ZOOM H5 Handy Recorder High Pass Filter applied with Audacity. This is my first ever recording with my new ZOOM SSH-6 Shotgun microphone.

I tried to aim at the feeding Terns but there is fans in operation to the right of me. The birds was feeding over the water and it was not so easy to aim
