Juno was a special case. She was ill-tempered and standoffish at first, but she rarely left Hill’s side after he nursed her back to health from an infection that clouded her eyes (though she also kept a parrot consort, another African gray named George). Juno enjoyed playing a game with Hill, captured on film by the BBC, in which she lay on her back in his open palm and let him toss her into the air and catch her again, over and over. “Up she comes and down she goes,” Hill wrote, “legs in the air, eyes half closed with pleasure, secure in the knowledge that she will land in my hand.”
