I used to have a pet goldfinch. I know thats illegal but I found it on the road along with its dead nest mates. It was still bald and pink. I was suprised it survived me taking it home on my bike and even more surprised when it turned into a goldfinch, I had thought it was a sparrow. It lived eight years,from me being 14 to 22, unfortunatly i could never release it because one of its legs were crippled. They sing a beautiful liquid trilling and it had a noise for people entering the room and a slightly altered noise for people leaving.
