"What's a Ghost Moose? How Ticks Are Killing an Iconic Animal"

"As New England winters get warmer and shorter, ticks are driving a worrisome decline in a species that's crucial to the region's economy."

"EAST MOXIE TOWNSHIP, Maine — Lee Kantar crouches over a dead moose calf and pulls a clump of hair from its straggly shoulder.

A few days earlier, the sickly ten-month-old animal had waded through deep snow to this sun-dappled stand of spruce trees in western Maine, laid down, and died.

'See how white those hairs are?' says Kantar, a moose biologist for the state.

It's a telltale sign that the calf was becoming a 'ghost moose' — an animal so irritated by ticks that it rubs off most of its dark brown hair, exposing its pale undercoat and bare skin."
