Amazonia Rio I - Fauna
Regarding animal species, biological surveys carried out within Amazon Rio I Sustainable Reserve and vicinity indicated the presence of 29 species of mammals, 210 species of birds, 18 species of amphibians and 85 species of fish. Pacas, agoutis, armadillos, deer, spider monkeys, howler monkeys, capuchin monkeys, tapirs, peccaries and catitus are among the main species of animals mentioned by the community during the participatory workshops.
Over the course of 82 km of dryland forest, 47 records of medium to large mammals were obtained through visual observation and collected material such as tracks, droppings, and skulls.
The presence of 29 species distributed among seven orders were confirmed, as presented in the Amazon Rio I and surroundings
The presence of large carnivores, such as jaguar (Panthera onca) and cougar (Puma concolor), indicates high environmental quality, and may be linked to low anthropic pressure, thus allowing the perpetuation of viable populations of these. Moreover, the presence of giant otter (Pteronura brasiliensis) in surrounding rivers, as in the Amazon Rio I Sustainable Reserve, can be considered a good indicator of environmental balance and water quality.
In the Amazon Rio I surroundings, 210 species of birds have been recorded, four of which are new species: the hawk (gavião in Portuguese) (Leucopternis sp), the antwren (chororozinho in Portuguese) (Herpsilochmus sp.), the tody-tyrant (maria in Portuguese) (Hemitriccus sp), and jay (gralha in Portuguese) (Cyanocorax sp). The geographic distribution of these four new species is limited, probably due to the small Madeira-Purus interfluve.
Another important result was the extent of the distribution of five species along hundreds of kilometers of forest: ocellated crake (maxalalagá in Portuguese) (Micropygia schomburgkii), least nighthawk (bacurauzinho in Portugues) (Chordeiles pusillus), black antbird (chororó-preto in Portuguese) (Cercomacra serva), citron-bellied attila (tinguaçu-de-barriga-amarela in Portuguese) (Attila citriniventris) and wedge-tailed grass finch (canário-do-campo in Portuguese) (Emberizoides herbicola), which indicates the heterogeneity of the area and the availability of resources throughout its length.
