last year I was in Yellowstone and was able to take some cool video footage of a large bison herd, including some male bison fights (in the distance). It was in late summer and the sounds of the bisons were really impressive. I think it already was some early stage of the mating season. Unfortunately the audio track of my video is really bad, mainly to lots of people talking and cars driving by. Those noices just kill the impressive ambience of the scene.
Therefore I'm searching for bison sounds the replace to audio track of my home video. At best some mating sound as heard in this YouTube video (not mine):
Can somebody help me with this?
Many thanks in advance.
