Along a narrow footpath that threaded through wide open farmland we came across a lonely outcrop of young and exposed oak trees. Their dry leaves hushed and rustled and hissed in response to the changing strength of the wind. It blew quite strong at times. We set up the microphones to record. The occasional lilting bird calls are from a buzzard, a broad-winged hawk that was circling the area. About five minutes into the recording a tractor began mowing a neighbouring field. These are the sounds of nature, the wind and of a worked landscape. At the end the buzzard flew right over us as we came to collect the microphones.
