In the context of Orchid and Hummingbirds near a Mountain Lake, explore the Heade's South America of the Background.
Heade began his study on hummingbirds during an expedition to South America, specifically Brazil, in 1863. He made two more trips to South America after that, with the third and final trip being in 1869–70. In South America, Heade spent his time studying the environment and sketching what he saw in its lively and natural form.
