Populations of hummingbirds are known to do well in Colombia thanks to favourable geographic and climactic conditions.

In Leonor Pardo's Enchanted Garden bird haven outside Bogota, ornithologists, photographers and environmentalists can observe more than 20 of Colombia's 147 species of hummingbird.
