It can be rather difficult to get a video of Rocky screaming since he usually stops once he sees the camera -- most of the screaming I've caught on video has been in the background when he's in a different room.
However, last night something was upsetting him, and he didn't care if I had the camera out.
Parrots can be loud! And Rocky, as a small macaw, is not as loud as some of the larger macaws or cockatoos. Even with all of the windows in my house shut, I have heard him from over 2 blocks away.
I'm hoping he's calmer tonight!
