My budgie used to like drinking whisky. Possibly. Least-wise he used to keep flying over when I was drinking it and taking a taste. He'd then throw half of it out of his mouth like it was poison and fly off. It wouldn't stop him coming back for more though.
I don't know if it ever had any effect on him. I'm not sure there's much difference in behaviour between a drunk and a sober budgerigar.
