Quick, agile, and fierce, the hummingbird is an amazing creature. Small for a bird but much larger than an insect, it’s able to hover in place and eat nectar directly from flowers. Many species use a forked tongue with curled edges that help it capture the sweet, viscous fluid. Even their distinctive sounds are fluid-influenced, coming from their wingstrokes and the fluttering of tail and wing feathers. (Image and video credit: BBC Earth)
