Jardin de los Picaflores, or Hummingbird Garden, in Puerto de Iguazu, Argentina, is a really cool place. The owner told me it took her 10 years to attract the large number of hummingbirds and passerines that now visit her property. There are 18 species of hummingbirds in the state of Missiones in Argentina.
