The margay may have infant distress calls down, but the lyrebird is the real impressionist of the animal kingdom. Indeed, its name may as well be spelled "liar bird" given its vocal talents. These animals have the most complex vocal chords of any songbird, and they use them to imitate any sound—other birds' songs, animal calls, orchestral music, construction work, you name it. The males build up a huge repertoire of impressions which, fittingly enough, they use to impress the females. Though they use their abilities for love, it's fair to say that lyrebirds have confused many of their neighboring animals with their dead-on displays.
