W: Good morning. My name is Janet. and I'll be your guide today. It's now 12:45. and we'll be starting our tour with the lion's den at 1：00. But before we begin, I have some important announcements to make. Please do not feed any of the animals and do not take any pictures using flash photography, as it does disturb the animals. The guided part of the tour will end at 2:00, but you will have approximately one hour to tour the bird and butterfly exhibits on your own before leaving the park. The gift shop is located right next to the parking lot where your bus will be waiting for you. Please feel free to ask any questions, and I hope you enjoy your visit.
