I watched what appeared to be two unprovoked attacks by Barn Swallows on other Barn Swallows. One of the victims was clearly a fledgling so I came to the conclusion that these were instances of a parent encouraging its offspring to not expect any more meal deliveries and to get off its butt and hunt for its own food.

Just chillin'. Taking a break on a fence.

Out of nowhere, along comes this interloper.

Slap, slap, slap, kick.

Scratch, claw, shove.

A final push. Is all this really necessary?

Again! Dad sees Mom coming at Junior, who is completely unaware.

Mom comes in from behind...

...and shows Junior what's what.
