The Bronx Zoo is home to lions, tigers — and now, a fleet of out-of-state ambulances that arrived this week to join the Big Apple’s war against COVID-19.

The 265-acre park, which closed to the public on March 16 because of the deadly bug, opened its gates to rescue crews from across the country Wednesday.

“Two hundred and fifty ambulances from around the country arrived to help NYC during the COVID-19 crisis and are currently staged in our parking lot,” the zoo wrote on its Facebook page above a video of the unusual emergency operation.

“We’re extremely proud and happy to help in this effort and provide a base for this critical operation,” the zoo wrote.

Zookeepers, deemed essential workers, remain on site to care for the animals.

Ambulances also massed at Fort Totten Park in Queens Thursday.

Earlier this week FEMA officials announced plans to send 250 ambulances and 500 EMTs and paramedics to the Big Apple to help the city contend with the “unprecedented” crush of calls to 911 during the coronavirus pandemic.
