Unknown animal in the amazon

["Mikel R. Nieto" mikelrnieto]

Hello folks,

I found this sound of an animal and want to know what it is:
http://soundcloud.com/mikelrnieto/unknown-animal
The recording was made in mamori Lake, near Manaus, in Brazil, during the
workshop that teaches Francisco L=F3pz in the rainforest.
I left the recorder overnight and picked it up at dawn, about 8 or 10 hours
of recording...
The fragment belongs at 6 o'clock in the morning.
I want to know which animal is that sounds before the bird ... any ideas?

Thanks!
