Eli LOVES ice! He gets it in his water every single day. We've had no issues except for melted ice on the floor when he throws it of course! Eli is a CAG by the way.
Julio (DYH Amazon) loves Ice Cubes in the summer months. Does much the same. Gets this big surprised look when they crash into smaller bits on the floor. He has not showed any signs of beak or head freeze, but has dropped an Ice Cube when he has held it to long.

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...
