A songbird can copy a chainsaw and a camera shutter closely enough to fool experts
The Australian superb lyrebird builds its courtship song almost entirely from mimicry, weaving together the calls of a dozen or more other bird species alongside sounds it's simply overheard nearby. Researchers studying the species have found its impressions accurate enough that even the birds being imitated can't reliably tell the difference. Captive lyrebirds have been recorded mimicking chainsaws, car alarms and camera shutters, though wild lyrebirds mostly stick to sounds of the forest.
