You're sitting on a peaceful lake, enjoying Nature's majesty and finally hooking a fish when, out of nowhere, an eagle dive-bombs in and steals your catch. What to do?
Go, "FUU--WAAAAAAH! AH! UGHH! Oh crap! CRAAAP! WAAH! WeeoAW! Whoo. Geez. Hah" and admit that you're just a visitor to the food chain, is what.
"Ima protected species biiiiiiiitch!"
That smug expression that eagles have probably comes from a lifetime of acting with impunity.
