Walking the forest trails at Sacha produces an unbelievable variety of species. A carefully planned itinerary taking in some tiera firme and varzea (seasonally flooded) forest will provide anyone with a superb selection of birds. Local knowledge is invaluable here and Sacha's guides know the whereabouts of roosting Common and Great Potoos. Evening walks produced Tawny-bellied Screech-Owl and Crested Owl.
