Parrots can imitate creepers, although creepers don't have any idle sounds

I'm confused by your description. Can you explain it further or attach a video showing this bug?

@Greymagic27
done

I think what he's trying to say is that, creepers don't actually make any sounds. The only sounds they make is footsteps, and the hissing sound is the same one TNT makes, so technically the parrots are not imitating the creeper's sounds...   or something like that, idk.

nah there's a sound for creeper hisses in the parrot while the creepe doesnt make it

I also heard creeper hissing sound when I was trying to tame a parrot, while playing minecraft. Although I didn't see any creepers around me. But there was a cave besides me. But when I moved away from the cave, the creeper sound disappeared. I tested this in a separate world and the sound was coming when parrot was near a creeper. I have attached a video of my findings.
