It’s East Hampton’s wailing whale.

A desperate, 30-foot baby humpback whale washed up on a popular Hamptons beach this morning, attracting hundreds of solemn gawkers who watched it bob and moan its way toward certain death.

Spotted several hundred feet offshore by an East Hampton Village cop at 7 a.m., the ocean dweller eventually washed up along the hamlet’s Main Beach and quickly drew saddened onlookers.

Officials said the whale is likely no more than a year old and appears to have been separated from its mother.

Unable to nurse or be artificially nourished, the whale is certain to perish, officials said.

Estimated to weigh several tons but still substantially underweight, the immobilized animal blew weakly from its blowhole and slapped its fins in the surf.

Parents comforted their disturbed children time the dying mammal emitted a plaintive wail.

“Its very sad,” said Chuck Bowman of the marine mammal rescue program at the Riverhead Foundation. “There’s just not much we can do in a situation like this. Without its mother, it’s starving.”

Bowman said that his crew would stay with the animal around the clock until its inevitable death and that it would undergo a necropsy.
