Mr. Mercat and I lived for about six weeks with some friends and their two parrots, Arturo and Farout. They hated each other. Arturo only spoke Spanish and Farout spoke English. Actually they mostly just chattered but Arturo chattered with a Spanish accent. They would stalk each other and each of us. The only animal I’ve ever lived with who could stare down a human. Weird.
Parrots are remarkable creatures, and are sometimes said to have the emotions of a human two year old. It sounds like those parrots you describe were both jealous of each other and suspicious and resentful of you and your husband as intruders.
