There’s a trick to getting sea snails out of their shells: hum to them.

“If you hold it close and hum gently, the vibration will cause them to peek out,” said Kellee Barbosa, program leader for children in the Massachusetts Audubon Society’s  Discovery Days program.

Kids learned that, and much more, while exploring the natural world during the day camp.

The free program is for children ages 6 to 10. The Massachusetts Audubon South Coast Sanctuaries runs the camp, which is funded through an A.D. Makepeace grant.

Barbosa leads the program, which operates Tuesdays through Fridays from 9:30 a.m. to 3:30 p.m. at either the Lyman Reserve or the Great Neck Wildlife Sanctuary until Aug. 26.

On Friday, the kids trekked down to a small beach on Sacred Heart Seminary property on Great Neck Road. There was no shortage of wildlife, or learning opportunities, on the walk.

Turkeys walked in the woods, butterflies flew over the trail and ospreys circled overhead as campers looked on with curiosity.

Barbosa explained that throughout the week different activities are held, such as scavenger hunts and nature-themed arts and crafts projects.

“I really like all the hiking,” said Sebastian Dumais. “I like being so close to nature, this is just my first year but it’s really great!”

Another camper, Tyler Tuchak, said learning about birds was a highlight.

“There are birds everywhere and we hear their calls,” he said. “And we saw the nests they made.”
