Both regions are tropical rainforests with high biodiversity, and popular media sometimes conflate their faunas. But biogeographically, the Atlantic Ocean has separated these faunas for ~100 million years.
To see toucans in the wild, visit the Amazon, Atlantic Forest, or Central American jungles—not the Congo.
