Wild horses of the Outer Banks unharmed after Hurricane Florence

Wild horses instinctively run for shelter in bad weather.

“[The wild horses] are in great shape,” Langone told ABC News. “They do have wild grass to eat. They have grasses that grow in people's yards.”

Langone said that wild horses instinctively run for shelter when they sense strong winds or approaching storms.

“Generally, in any storm they tend to, what we term, ‘hunker down,'” Langone explained.

Langone said the herd of wild horses has more than 7,000 acres of land to roam.

"They can go anywhere from out on the beach area to back behind the dunes where they frequent a lot because there is more food available,” Langone said.

Though the Corolla horses are safe, Langone said that she is worried about other groups of wild horses that could be stranded in flood waters.

“We are more concerned about those horses that are still caught in flood waters," she said. "It's all to the south of us.”

At least one of the southern herds survived unscathed, a government official said.

The Ocracoke ponies on Ocracoke Island were all reported safe, according to Mike Barber, a spokesman for the National Parks of Eastern North Carolina.

"Ocracoke Island did receive some impacts from the storm but we're happy to say that the Ocracoke ponies were not impacted,” Barber told ABC News. “We have currently 15 ponies, and they're all doing well right now.”
