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.
Isto foi gravado numa reserva de gibões, o que explica você poder ouvir tantos deles. Mas o som mais importante que vinha da floresta naquele momento era um que eu não havia notado, e na verdade, ninguém ali havia notado realmente.
