Bowie, my Green Cheek, recently discovered what "carbonation" is, as he decided to help himself to a drink of my San Pellegrino Blood-Orange carbonated water while I wasn't looking...You want to see a "surprised look" on a bird's face!!! He first looked terrified and started shaking his head, and actually jumped-onto me, which is what alerted me that he was doing something he shouldn't be (I was talking to a customer on the phone and not paying attention to what he was doing, my bad). He then jumped right back over onto the desk and did it again, then I realized what he was doing...Surprisingly he decided that he didn't like it and was actually scared of the can...
