觀察細節
I played a “grunt display” at the marsh where the rail was recorded on the 4th of December. As soon as I played the call I immediately turned on my recorder and waited. Within just a few minutes a loud “grunt display” call was heard down and to my left. Very soon after that call a faint “display call” can be heard coming from across the marsh, up and to my right.
