I have come to the conclusion that Grizelda, my bird, is actually Canadian. I base this on the fact that she boisterously sings along anytime "Oh, Canada" comes on as we watch the Olympics. She doesn't do this for any other songs, and completely ignores the "Star-Spangled Banner" (which I can sort of understand; it is rather un-singable). Her taste in music is different than mine; she likes avant-garde jazz, which I'm rarely in the mood for, and ignores jam rock, which I usually play. But because I'm a good people, I've downloaded several versions of "Oh, Canada" for her pleasure. She may not sing well, but she sure does sing loud when she hears any of them.
So I have a very rare type of bird, the Canadian Grey Cockatiel.
