The zoo has installed lighting in a large portion of its new video and live animal exhibits.
The new lighting system will be installed on the exterior of the zoo, which is now under construction.
The lighting is designed to help conserve the animals and reduce their reliance on artificial lighting.
The zoo is installing the new lighting after more than two decades of using natural daylight, which creates problems for the endangered African elephant and other animals, including tigers.
Zoo officials said they’re trying to make the zoo more sustainable by reducing energy use.
