Been through 2 (minor) earthquakes and one sonic boom -- my parrots took it in stride. I had to see the news to even know what had happened each time (east coaster here). But each time when I felt the whole house shake and could see my chandelier swinging -- I was a little freaked out. My dog started panting and pacing (as she did during thunderstorms) - wanting my comfort yet unable to settle herself enough to accept my comfort.... But parrots? Ya just never know how parrots will react. I think my parrots always found some joy through a little drama. lol Would NOT want to know what a serious earthquake would do. (shudder).
