At the risk of repeating recent posts from MB and CFB, John, Paul and I visited the boardwalk area of Cors Fochno last night and had a churring male which then treated us to a display, including calls and the odd wing-clap.
We then found another one churring on the way back to the car.
A word of warning, though. On a warm and calm evening the midges were as bad as I've ever known.
