Ages-old Chase

The other day, out at the Shoreline Preserve, I stood and watched as a raven pursued an immature eagle; and wondered how long has this been going on? Centuries, most likely.
Catching the birds in air does not allow much context to the photo, so by blowing out the background we get to see the shapes instead with only a little bit of detail. Detail really isn't needed here as the shapes provide the story - or at least the outline.

I would love to know what they were saying to each other right then!
