You may not be familiar with south Georgia (Georgia Southern) Eagles, specifically the GSU GATA-Eagle.
These powerful creatures dwell primarly on the ground, consuming huge tracks of yardage which may leave wandering Bison in a state of wonder. The GATA-Eagle has a possessive nature and has been known to hold trinkets (such as footballs) for excessive periods of time. Additionally, GATA-Eagles are very territorial and strike hard and often at any intrusion into their territory. GATA-Eagles are extremely intolerant of any attempts to penetrate their nesting areas, often found at the very end of a football playing field (endzone).
It is also noteworthy that GATA-Eagles are respectful of other creatures who happen to share the same territory. I feel certain that their treatment of any native Bison will be firm, but fair. We would ask that the Bison simply steer clear of the field and let the GATAeagles have their fun, but given the inate dignity and pride of the Bison, we understand that is unlikely.
We wish you the best, but (understandably) not all the best.
It's very easy for Eagles to poop on the heads of little trolls, while they're in the wide open fields stirring up bison patties.
