Humpbacks are invading New York City!
Maybe they want to sing on Broadway.
Humpback whales have been approaching New York City in greater numbers. They are gigantic, endangered mammals. They are known for their haunting underwater songs,
The whales have been spotted in the Atlantic Ocean within a mile of the Rockaway peninsula. That is part of New York's borough of Queens. It's also within sight of Manhattan's skyscrapers.
"It is truly remarkable ... to have one of the largest and most charismatic species ever to be on this planet," said Howard Rosenbaum. He is director of the Ocean Giants program. It's part of the Wildlife Conservation Society.
Humpbacks were spotted 87 times from the boats this year. By cataloging the whales' markings, at least 19 different humpbacks have been identified off the city.
Paul Sieswerda is founder of Gotham Whale. The organization documents the marine mammal population around New York. It said reports of humpbacks in the New York Bight, where the city's harbor meets the Atlantic, began to pick up around 2010. Gotham Whale then partnered with the American Princess whale-watching boat. Gotham Whale provided naturalists to document the sightings.
The naturalists also do an educational presentation on the boat, said Tom Paladino. He is the boat's captain.
"It was pretty slim pickings at first, actually," Sieswerda said. "We went on many cruises and had three sightings totaling five whales in 2011."
But in 2012, there were 15 sightings. In 2013, there were 33. This year there were 87 sightings totaling 106 humpbacks.
Many whales were sighted more than once. By comparing the shapes and markings of their tails of the whales, 19 different humpbacks have been documented near the city. Customers on the whale-watching tours are asked to share any photos they get of the markings. The pictures can be included in the "New York City Humpback Whale Catalog."
Humpbacks can be 50 feet long and weigh 40 tons. It's not clear why they are returning to New York's shores. They and other whale species were nearly destroyed by whaling.
Rosenbaum said the humpbacks' reappearance could be simply a shift in their habits. Menhaden is one of the whales' favorite foods. It's been in greater abundance recently. The small fish could have attracted the whales.
That might be because the water is cleaner.
Sieswerda agreed that various factors are in play but said, "I think it all begins with cleaner water."
Whatever the cause, humpback populations worldwide are increasing. Counting whales is difficult. The worldwide population is estimated at about 150,000. About 11,600 are in the Western North Atlantic. The area includes the New York Bight off New York City.
New Yorkers shouldn't expect to see humpbacks frolicking around the Statue of Liberty. The whales generally stay well outside the harbor.
