PETA is offering $5,000 for help in catching whoever drove into a flock of shore birds on the beach in southwest Washington and killed 92 of them.
KING-TV reports the dead Sandpiper-type shorebirds called "Dunlin" were found Thursday north of the Cranberry beach approach on Long Beach.
Wildlife Center of the North Coast said the trauma the birds suffered is consistent with a collision with a motor vehicle.
Seabirds and shorebirds are protected under state law. It is illegal to harm or kill them.
Fish and Wildlife Police say a vehicle has to be travelling considerably faster than the posted 25 mph speed in order to hit these types of birds. Dunlins are able to reach speeds of 110 mph.
Anyone with information is asked to contact PETA at 757-622-7382 or Sgt. Dan Chadwick of the Washington Department of Fish & Wildlife at 360-581-3337.
