The zoo at the city’s Bronx Zoo has become the first in the United States to install automated zoos, a move that comes after the National Zoo in Washington DC installed automated zoo-style enclosures in September.
The Zoos of the Americas, a nonprofit that promotes the use of artificial habitats, has also been using automated enclosures since 2014.
Zoos around the world are also using automated facilities, including the largest in California, the California Aquarium.
Zoo operators say automated enclaves are ideal for large animals and are easier to care for.
They also say they reduce costs and waste.
The zoos have also come under fire for the treatment of their animals.
Some activists say that captive animals are kept in deplorable conditions that are too cold and that animals are abused or die of heat exhaustion.
The zoos deny that.
But animal advocates and human rights groups say the practice is often mistreated.
They say zoos use captive animals for breeding, entertainment, and entertainment purposes.
They contend that captive birds and reptiles are not allowed to live or breed freely.
