The place where this was recorded was in fact a gibbon reserve, which is why you can hear so many of them, but in fact the most important noise that  was coming out of the forest that time was one that I didn't notice, and in fact nobody there had actually noticed it.
Ljuden spelades in i ett reservat för gibbonapor, det är därför man hör så många, men det viktigaste ljudet var det som jag inte noterade, och faktum är att ingen annan heller hade noterat det.
