Officials in a small Oregon fishing village have deployed a giant, motorized fake killer whale to scare off hundreds of sea lions thct have made the local port's docks their new home.

City leaders in Astoria, Oregon, say are hoping the 32-foot-long (10-meter) faux orca will succeed where such tactics as electric mats and brightly colored beach balls placed outside the docks have failed.

"It really is a sign of how desperate the measures are that we're taking to try and solve this problem," Port of Astoria Executive Director Jim Knight said. "We simply don't have the financial resources to build barriers. We have no choice but to look for very creative and low-cost solutions."
