The Bronx Zoo announced this week that it will be reopening at the end of July. But for months, it has been not visitors but just animals and essential workers in the wide green expanse. And some of the animals notice the lack of people, says zoo director Jim Breheny. Episode 33 of “Life Under Coronavirus” is an interview with Breheny, who has worked at the zoo since age 14. The pandemic was a challenging time for the zoo, which stocked up on food and worked hard to keep workers and animals healthy. It also was home to some interesting sights, like bears and giraffes, and other animals suddenly interested in viewers.
