popcorn

Hello, I just received a MicroPop microwave popcorn popper as a gift. I have a cockatiel and am wondering if it is safe for her. It appears to just be a glass pot with a silicone or plastic lid (it says BPA free). I cannot find any information about it online! This is what it looks like...

I want to fix Gloria (BFA) some holiday treats. I was thinking of stringing some plain popcorn and cranberries for her--like I used to do for the outside birds. Is this a safe treat? I just pop plain popping corn in the microwave with no oil or salt and the cranberries are raw organic ones...
