SEA BRIGHT, N.J. (AP) — A group of 15 dolphins that have taken up residence in a river near the Jersey Shore will be allowed to stay there through the July 4th weekend, even though a nearby fireworks display draws heavy boat traffic.

Federal environmental officials say the danger of trying to move or scare the dolphins back into the ocean outweighs the risk of letting them stay in the Shrewsbury River.

"They're evidently in good condition," said Teri Frady, a spokeswoman for the National Oceanic and Atmospheric Administration. "We have no reason to think they're incapable of getting away from things that disturb them."
