When it comes to pollinating, most flowers employ mobile agents like the hummingbird to transfer pollen from bloom to bloom. Plants do not produce showy flowers simply to delight humans - they expend the huge amounts of energy required in their production only to attract pollinators. Hummingbirds not only use flowers as a food source but also as a mating site, where many flowering species present a fun and playful environment.
The mutual desires of flowering plants and the birds which are their pollinators, argues strongly for the preservation not only of individual species but of whole, healthily functioning ecosystems.
