Ecuadorian Hillstar cards with males incubating their eggsThe Ecuadorian Hillstar is a small hummingbird with iridescent green feathers on its back and head, contrasted by a white belly. Found in the high altitude regions of Ecuador's Andes Mountains, it is the only hummingbird species known to regularly visit high elevation grasslands. A fun fact about this bird is that it has specially adapted feet that allow it to walk on the ground, unlike most hummingbirds.
