An aggressive owl is reportedly attacking joggers and making off with their hats, The Guardian reports, noting four separate attacks over the past month.

“It just pulled it right off my head like it was nothing!” said park visitor Brad Hilliard, 36, who is now missing a hat after a run.

The flying culprit, thought to be a lone assailant, is likely a barred owl species, forest experts said. It has been swooping down upon park visitors, shocking rangers, who say they’ve never seen such aggression by an owl before.

Members of the Audubon Society said it is nesting season for owls and that could be the reason for the attacks.

While no one has been hurt, fears of future airborne thievery have prompted park officials to post signs jokingly warning visitors to avoid their runs or ponder wearing a hard hat for jogging, The Guardian said.
