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.
Aufgenommen wurden diese Laute in einem Gibbon-Reservat -- deswegen hört man so viele. Aber das wichtigste Geräusch  aus dem Wald damals bemerkte ich zuerst gar nicht. Genau genommen hat es  niemand wahrgenommen.
