An owl that achieved notoriety last winter for attacking joggers in an Oregon park has returned and is now turning its talons on government workers, state officials said on Wednesday.

The barred owl has clawed at least three people outside the state Capitol in Salem in a series of attacks since late November, city parks department spokeswoman Tibby Larson said.

"It's silent. You're just walking along, minding your own business, and an owl comes silently at you from behind," Larson said.
