I posted this on page 3 of the
Rare sea creature found on Seattle dock thread. That
thread told the story of a Ribbon Seal found in Puget Sound near the mouth of the Duwamish, a very polluted water-way.
I was thinking how far south this seal has traveled, and it reminded me of an article I read this month about Snowy Owls found in the area. Snowy Owls
are also from the arctic, and this year they are showing up as far south as Oregon
Here is one link to a local article about the Snowy Owls.

Using a Google news search, I found additional articles on owls spotted in the midwest.
I'm not saying arctic creatures moving south is become an epidemic, but with the spotting of the seal and the owl, I wonder why they are here.
I don't think they are here because of the wintry weather we are having. The owl showed up before the snow/ice storm.
Is it possible that the climate is changing up north? Either getting too cold or too warm and they can't find their normal food or stay comfortable?
According to Wikipedia, the ribbon seal lives year round in the arctic. They have only been found south two other times, and both times they were
healthy. I don't know about the health of the recent seal. I do know that the animal was found in a very polluted area.

Wikipedia says the snowy owls have been found south before, but most of their lives are spent in the arctic.

I'm wondering if they are fleeing some sort of change, such as radiation contamination, pollution, or something geological.
Do these animals use magnetic field to get around, and now they are getting confused? If the magnetic field is changing, like its been speculated, it
could affect them. I'm assuming they do, but I've yet to find any confirmation. they use magnetic field to get around.
Of course, having two rare arctic animals show up in the PNW, isn't something to cause too much alarm. We may have got lucky this year.
What do you think?
