I assume they're trying to attack you or think you're prey.

"Mean"? Absolutely nothing....mere chance. OR.....slight possibility that you were too close to *their* territory. Bluffing you away.

Wow - how interesting is that! Never heard of that - but probably they have a nest in the area and are seeing you safely to the boarder of their domain. Maybe..... You got to figure though that even birds have a "sense of humor" - they'll pull gags on other animals - a chicken might grab the dog by the butt and make the dog run away. Perhaps these eagles were just curious or trying to be "funny".
