A Bosnian accent???
Honestly, I wouldn't know! LOL!
The video isn't my bird. That one sounds British to me. And singing Jingle Bells, too! A seasonal video
I got Sophie from a rescue last year. When I was told her previous owner was foreign, I asked if she had an accent or spoke a foreign language. I was told, no, she doesn't talk. Half an hour after I got her home, she said, "Hello.". Definitely had an accent, lol! A bit later she asked me, "Who are you?". Yep, accent, and a rather smart thing to ask. So I contacted the rescue to ask what country her previous owner was from, and was told Bosnia. She now has more than 20 voices.
