If you go to the zoo during the day - you can see that things are hopping! Animals are being cared for, people are milling about, and there’s a lot of action to observe. But what happens at night? Who takes care of the animals then? Or is everyone just sleeping? We asked Nancy Hawkes, Director of Animal Care at Woodland Park Zoo to help us find the answer.

Got a question that’s zookeeping you up at night? Send it to us at BrainsOn.org/contact, and we’ll help you find the truth – we won’t be lion!
