A 70-year-old Alaska man who was attempting to take photos of two newborn moose calves was attacked and killed by their mother, authorities said Monday.

The man killed Sunday was identified as Dale Chorman of Homer, said Austin McDaniel, a spokesperson for the Alaska Department of Public Safety.

The female moose had recently given birth to the calves in Homer.

“As they were walking through the brush looking for the moose, that’s when the cow moose attacked Dale,” McDaniel said.
