That's so sad. I've seen them circling overhead when I have my parrot out. I see them take off with bunnies and squirrels. Breaks my heart. I had a similar tragedy several years ago. I had my eclectus sweet boy in a room in the basement with me while I was working on something. My new ferret was in the room too, in his cage, sleeping. My son came in the sliding glass door right where my bird was and wanted to show me something that was "in the pool" right outside the door. I went out and told my son to get the net. When he picked up the net, it spooked my parrot, who "flew" to the floor. Apparently, the ferret hear the sound, which woke him up. He escaped through an area of the cage I didn't realize was escapable and ran over and bit him in the back of the head. He died in 3 mins. Worst experience of my life. I'd had the ferret less than 24 hours. I'd had the eclectus 3 years and he was a joy.
