Officials say burials are being ramped up at site, which has long been used for people with no next-of-kin or families who cannot afford a funeral.
New York state now has more coronavirus cases than any single country.
The state’s confirmed caseload of COVID-19 is almost 162,000, of whom 7,067 have died, according to Johns Hopkins University.
Spain has recorded about 157,000 cases and Italy 143,600, while China, where the virus emerged last year, has declared 82,000 cases.
The US as a whole has recorded 466,000 cases and nearly 16,700 deaths. Globally there are 1.6 million cases and 97,000 deaths.
The drone footage comes from Hart Island, off the Bronx in Long Island Sound, which has been used for more than 150 years by city officials as a mass burial site for those with no next-of-kin, or families who cannot afford funerals.
Normally, about 25 bodies a week are interred on the island, according to the Associated Press news agency.
But burial operations have increased from one day a week to five days a week, with around 24 burials each day, said Department of Correction spokesman Jason Kersten.
