So we have a lot of really cool animals back there.

My name is Kelli Carroll.

We're here at the Lake Superior Zoo at our nocturnal building.

And I'm one of our zookeepers.

And I'm going to be teaching you about our nocturnal lights today.

So our nocturnal animals are on a nocturnal light cycle.

So what that means is when guests come to the zoo, they'll walk back there.

It's nighttime for those animals.

So it's very dark back there.

Which is just how the animals like it.

Since these guys would be awake at night.

So we have animals back there that people have definitely heard of before.

When it comes to nocturnal animals like our bats, our sloth, and some animals that people probably don't think of as nocturnal or haven't heard of at all.

Like maybe our ermine or our large spotted Genet's, or our spiny mice.

We have three different light switches that turn on or off to mimic dawn and dusk.

So it's a very gentle transition into dawn and dusk, just like it is in nature.

We can spin these around to mark what time it is right now.

And then this is our on switch.

It's honestly very similar to having a Christmas light timer.

It's just for, a little more expensive lights.

There aren't many facilities out there that have nocturnal houses because it is challenging to run one.

It's a really cool educational experience to be able to teach people how much diversity there is.

When the lights turn off or when the sun goes down.
