It's called a Lyrebird. http://video.google.com/videoplay?docid=3433507052114896375 Can mimic all the birds in the forest, car alarms, camera sounds. Pretty damn cool.
the birds in the parking lot of school will whistle back whatever you say, so we'd get high and then go talk to the bird it was great
haha my neighbor has a like parrot type thing that can talk by itself and it mimics my dogs barks and my whistles and stuff so my dogs run around my backyard all confused and shit
