There is a new warning for Nassau County following recent coyote sightings.

The town and Nassau SPCA say there were recent coyote sightings at the Shu Swamp Nature Preserve in Lattingtown and other North Shore communities this week.

Oyster Bay Town Supervisor Joseph Saladino, Councilwoman Michele Johnson and Nassau County Society for the Prevention of Cruelty to Animals Board President Gary Rogers issued some safety and behavior tips for residents.

Roslyn college student Molli Michalik says she had an encounter with a coyote in August.

"I was waiting at the light on Shelter Rock Road, and I saw what looked like a huge dog and I realize, that's not a dog, that's a coyote," Michalik says. "It was gigantic, it was big, and it just crossed the street and disappeared into the trees."

Experts say do not allow coyotes to approach people or pets. If you see a coyote exhibiting threatening behavior, dial 911.

Some safety tips include not feeding the coyotes, do not feed pets outside, eliminate availability of bird seed, make certain that garbage is inaccessible to wildlife and teach children to appreciate wildlife from a distance as to avoid the risk of being injured.

Experts say under normal circumstances, coyotes are not aggressive.
