The fun thing is there's a line through my property. The eagles' territory is west of the line, the hawks' is to the east. Sometimes they fight over the location of that line.
The hawks are half the size of the eagles, but they don't take no ** from the eagles, and it's a fair fight. The hawks usually win the tussle and drive the eagles back over the line. It's like a WW1 aerial dogfight.
And this is in the middle of the Seattle metropolitan area.
