A humpback whale swam through New York’s Hudson River on Thursday, drawing crowds of onlookers to the waterfront.
The sighting, which sparked immediate activity across social media, was captured in photographs and video by Gotham Whale, a citizen science and education group that tracks marine mammals in the city’s waterways. Brad Hoylman-Sigal, the president of Manhattan borough, was among those who shared images of the animal on Facebook following the morning sighting.
The presence of the whale in such a busy maritime corridor highlights a shifting ecological pattern for the region. While sightings of humpback whales in New York waters were once considered rare, they are becoming increasingly frequent as the population recovers and moves through local channels.

According to The Guardian, Gotham Whale documented 272 whale sightings in the city’s waters in 2018, and the group has continued to record numerous glimpses in the years since.
These more frequent visits challenge the animals. As more whales enter the busy shipping lanes of the New York area, the likelihood of human-related accidents rises.

The danger to the species in these crowded waterways is significant. A report from The New York Times in January likened the risk to whales navigating these paths to “deer crossing the road,” noting an increase in the number of whales found stranded.
The specific details of this Thursday sighting remain limited. It is not yet known whether the whale is male or female, or if it arrived in the Hudson alone or was swimming with company. Humpback whales are typically solitary, though the environmental group Whale Trail notes they can sometimes be seen in social groups of 10 to 15 when feeding.
The scale of these animals is immense. Adult males can reach lengths of up to 48 feet and weigh as much as 40 tons.
By early Thursday afternoon, the whale was still present in the river, with observers capturing video of the animal rolling over and spraying water from its blowhole as onlookers cheered.
