My sennie is a screamer. I've been ignoring it, but it keeps getting worse. I've heard that senegal parrots are supposed to be very quiet, but mine is not. I live in an apartment building with close neighbors, and I'm sure they probably hate us. He screams when I leave, to get attention, and just because he feels like it.
Fortunately, my other two don't join in the mayhem.
Thank goodness he's not a macaw, cockatoo, or even a conure. But his scream can be heard clear down in the parking lot. I hope he doesn't scream when I'm away...
