I started to post on this back when they were first spotted going up the river. Got busy and just did not get around to posting it. Then for a couple of days it was reported they were just hanging out on the river. Then they were reported going downstream and leaving. Then the reports said they were gone. Then the bodies of two were found. Then a few days later the body of the third on was found.
The biologist I talked to feel the Orcas went up the river chasing Baluga Whales and Salmon. The Balugas were chasing the salmon, that's what they eat. Once up the river the Balugas, being familure with the area was able to sneak by the Orcas and go back downstream and out into Bristol Bay. The Orcas were busy chasing and eating Salmon. Then got disorentated and was not able to find their way back out of the river. Oh well, life goes on. Part of Mother Natures big plan. You know the old saying, "Stupid Ones Should Not Breed"! Well, Mother Nature has a way of seeing they don't.
First it was save the Whales. Now it's save the Otters. Orcas eat Otters, but some people can not understand that. Orcas are meat eaters, they eat Fish, Otters, Seals, Sea Lions, other Whales, and anything else they find swimming in their ocean.
