* that's cute, but it doesn't address the huge piles of shells on
Beaver-trampled shores in northern Ontario where the local trappers say
there are few or no Muskrats.
I'm just saying that the pattern of shells in Nancy's photos is similar
to what I've seen repeatedly around Beaver lodges, starting in the
Ottawa River at Morris Island in 1995. We evidently need some sort of
electronic monitoring to get evidence of this - but if Beavers do a lot
of their predation under the ice in the winter, or even underwater in
the summer, even trail cameras wouldn't suffice.
Has anyone on the list seen a mammal eating a freshwater mussel?
