Nanaki Singh was strolling dwelling final week, hours after the remnants of Hurricane Ida turned many intersections in the Brooklyn neighborhood of East Williamsburg into knee-deep ponds, when he seen a lifeless rat mendacity smack in the center of the sidewalk. And one other. And then one other.

“I saw a total of six dead rodents within 10 square feet,” Mr. Singh, 23, mentioned in a Twitter message to The New York Times on Thursday. He posted photographs of the proof on the social media website, together with some somber commentary and an “R.I.P.”

He was not the one one to note that the storm had left a phase of the town’s rat inhabitants — which has by no means formally been counted, though estimates vary into the thousands and thousands — distressed, displaced or deceased.

On the shorelines of Jamaica Bay in Queens and Brooklyn, walkers noticed an uncommon quantity of lifeless rats on seashores, as first reported by Gothamist. On the Upper East Side, one resident noticed not one however three dwell rats skitter into her constructing, one stepping on her foot alongside the best way.

Scientists who research city rats mentioned that the surge of water that coursed via streets, pipes and basements final week probably drowned 1000’s of rats and disrupted the habitats and feeding habits of many extra.

“Just like people were caught off guard by the swell of flooding water coming down the streets, it’s possible that some of these rats also couldn’t get away in time,” mentioned Jason Munshi-South, a professor of biology at Fordham University.

More rats dwell in sewers than in the subway, primarily in the older pipes which can be made of brick; rats even nibble out mortar and burrow into the crevices. The pipes often comprise some air, and rats are comparatively good swimmers, Dr. Munshi-South mentioned — however with storm water so overwhelming the system that water gushed like geysers out of bathrooms and manholes, many might have been swept below by strain or lacked sufficient area to take a breath.

But the rat inhabitants will greater than survive this newest disruption, because it has many others. Early in the coronavirus pandemic final 12 months, when restaurant closures diminished the provision of tasty scraps, the rodents improvised by discovering edible pickings in residential rubbish, which elevated with the suspension of compost packages.

And in any case, scientists say, rats reproduce rapidly and recoup any dip in inhabitants inside months.

“From what I saw this summer,” Dr. Munshi-South mentioned, “the rat population is quite healthy.”
