This is a video of a little lyrebird making laser gun sound effects (among other sounds). Lyrebirds, if you weren't aware, are some of the animal kingdom's greatest mimics, and mimic the natural and artificial sounds they hear in their environment. Obviously, this particular lyrebird appears to have been raised in the middle of an epic space battle.
Keep going for the video, as well as the one from David Attenborough's series with more impressive lyrebird mimicking (although the car alarm and chainsaws always make me kind of sad).
Thanks to Dan G, who agrees that bird has probably seen things that would make an astronaut blush.
