Hummingbird


The male hummingbird attracts a mate by doing steep aerial dives to produce a ‘song’. The sound is made by the wind passing through their tail feathers. Hummingbirds, which are the smallest bird in the world, can tweak their tail feathers to amplify the sound, with each species of hummingbird having its own signature sound.
