Hey! There's a Bird on Your Head - 2011 Project 365 - Day 188 of 365

"Hey! There's A Bird On Your Head"

A bison trying to get some rest on a hot summer day doesn' t even realize that there is a cowbird on his head.

Cowbirds follow herds of bison to catch and eat the insects that are stirred up from the bison's feet. The bison allow the birds to sit and rest as they guard them from the pests. It is what is called a symbiotic relationship.
