Polar Bears Are Morons (Maybe Not)

A study claims Polar Bears are swimming longer, tiring them out and that maybe cause them problems.

The Polar Bear Science Blog points out the obvious:

So, despite what may be implied during media moments, Beaufort Sea polar bears were  not frantically trying to reach the sea ice from land so that they could attempt to keep feeding over the summer – most of their swimming was done during breakup in July and August from one bit of pack ice to another and they showed no evidence of harm from doing so.

What do you think? Do you think they swim like this (avoiding all ice floes):

Or like this (jumping on ice floes for a rest when they need it):
