The Bird Park (Parque Das Aves in Portugese), located in the town of Foz do Iguacu, near the famous Iguacu Falls right on the border between the three nations: Brazil, Argentina and Paraguay is a great attraction itself. It's set within the 16 hectares (40 acres) area of sub-tropical rain forest and provides shelter for around a thousand birds (150 species) as well as butterflies and reptiles from both all South America and other exotic places. The park is privately owned and very well maintained. It was opened in 1994.
