Humpback Whale Spotted Last Week in Hudson River

Monday, December 14th, 2020

The Statue of Liberty had a surprise tourist last week!

A humpback whale was spotted in the Hudson River on December 7th & 8th in the vicinity of Liberty Island. Video and photos of the whale were posted to Twitter as boaters took notice of the large marine mammal.

New York City Parks Department confirmed the citing on their social media on Tuesday:

“Whale sightings have increased in recent years in N.Y.’s waterways. Reasons for the uptick may include an improvement in local water quality, & an abundance of food sources like Atlantic menhaden.”

Marine wildlife education group, Gotham Whale, also posted about the sighting, tracking the animal during it’s visit and urging boaters to exercise caution while traveling on the Hudson.

Humpback whales are a rare sight in the Hudson, but are hard to miss due to their size and perchance to show off by frequently surfacing and breaching. The last humpback to find it’s way to the Hudson was in 2016, when a humpback took up a week long residence in the busy waterway.

ACTION ALERT: Support ecological management of the most valuable public resource for our coastal ecosystem and economy

The Atlantic States Marine Fisheries Commission is accepting public comment on the establishment of ecological management of Atlantic menhaden (Brevoortia tyrannus), which is a keystone species. Basically, a keystone species is one that plays a large role in the ecosystem where it lives. If a keystone species is lost then the ecosystem would dramatically change or cease to function, causing widespread effects to other species that benefit. In New Jersey, ospreys have largely benefited from a healthy menhaden population as we’ve had relatively high reproductive rates (more than double what’s needed to sustain population) over the past decade. From 2006 to 2016, the population has grown by 30% and above the pre-DDT, historic milestone of over 500 nesting pairs. Around 82% of the state population of ospreys nests along the Atlantic Coast and we observe menhaden at a huge number of nests during our mid-summer surveys. If menhaden numbers drop, then we will likely see osprey numbers follow suite, as reproductive rates will decline, as they are in the Chesapeake Bay.
