Mystery May Be Solved Surrounding Severe Pelican Injuries

Each day, a few more dead or injured pelicans are spotted at Port San Luis. But over the weekend, investigators may have an answer to who or what is causing the peril surrounding these birds: sea lions.

Department of Fish and Game Officials made the revelation this weekend, when new evidence surfaced at Port San Luis. It was there that some weekend kayakers saw pelicans dive down to catch fish and then watched sea lions surface, grab the birds, and pull them under the water.

The pelicans either disappeared or resurfaced and flew away with visible injuries.

...Based on the injuries, and possibly teeth marks, Fish and Game Investigators should be able to determine if sea lions are in fact to blame.

Wildlife officials are asking hunters to keep an eye out for dead deer in western North Dakota that could indicate the presence of epizootic hemorrhagic disease.

According to Dan Grove, wildlife veterinarian for the Game and Fish Department, about 20 dead whitetail deer have been reported in four western counties — McKenzie, Hettinger, Slope and Golden Valley.

Grove said the deaths have characteristics similar to previous EHD events, though biologists have not yet confirmed the cause of the deer deaths.
