Hitch Hikers

I rarely visit Antelope Island in the winter. It’s usually deserted and windy.
During my last visit I saw only bisons who were surrounded by birds.
The bisons did not seem to mind the hitch hikers on their backs,
I am not sure they even noticed the birds.

Later I will learn that certain species of birds ride on the backs of Bisons
and feed on the insects they find in the Bison’s fur.
European Starlings are among those birds.
