TILLAMOOK, Ore. Oregon Department of Fish and Wildlife workers are scaring off birds to protect spring salmon along the coast.

For the next month and a half, ODFW staff and volunteers will haze cormorant sea birds in several coastal estuaries, the agency said Monday.

The young fish are making their way to the Pacific Ocean. The birds can eat up to two pounds of fish per day, in what ODFW called a significant threat to the outbound migration of salmon and steelhead.

The volunteers will be driving at the flocks in small boats and, occasionally, firing at them with small pyrotechnics.

Cormorants are protected under the Migratory Bird Treaty Act, so they will be careful to not injure or kill any of the birds.
