Nature: The Flight of the Condor: Down the Amazon

The third part of the series is a spectacular visual trip down the fabled river. From the snow-clad summit of the volcano Cotopaxi and others comes the greatest river in the world as melting ice creates a torrent that drops three miles in its first short distance. The river is fed by magnificent waterfalls and is channeled through gorges out into the tropical rain forest where there are more species of birds than anywhere.
