I've never had a pet parrot before, but it's pretty common knowledge that they'll imitate pretty much whatever they hear. Even the sounds of sweet passionate love making, which apparently this bird has witnessed a lot of. Check out this horn-ball bird.

I always thought it would be sweet to own a talking bird so that I could teach it swear words and how to say "Fantone is Awesome" every time I walk into the room, but I never even thought of having sex in front of it.  It's good that it's just making the moaning and groaning sounds too, because I've said some pretty messed up things during sex.  I'm not sure about your but I wouldn't want to hear my pet bird saying "Shove your panties in my mouth" or "Spit on it and smack yourself in the face with it".
