Hummingbirds became experts at reaching nectar in flowering plants and in turn, many flowers such as trumpet plants evolved down a path that invests heavily in hummingbirds visiting them. I have seen some clever orioles circumvent the process of nectar in exchange for pollen by snipping a hole in the bottom of a trumpet plant flower and drinking the nectar it wouldn't be able to reach otherwise.
