They're gone now, was empty the last time I visited. I wanted to go yesterday, but the weather was supposed to be terrible (long drive to Dallas). Of course, it ended up not raining at all... I'll update this again when I visit.
@jayjds2 I recently went and it was empty, however the paper sign saying whatever is in there was off exhibit had a picture of what looked a lot like a juvenile bali mynah. That is probably just a picture they used, but could it be possible they are putting juvenile bali mynah in there?
