My grandparents got several birds like that (Goldfinch, Blue Bird, and... something else) one year for Christmas (we do presents Christmas Eve). I grew up with my Grandparents, and I remember walking down the stairs Christmas morning (it was like 2:00 AM) to get something from the kitchen. All the sudden I heard all these birds talking. It scared the
out of me. I fell down the stairs, and started screaming. I woke up everyone staying there that night. That was probably 10 years ago, but they still have those birds and I still don't trustem.
