All bank angle and speed

 As below, so above...

This morning, there was a swarm of gnats hovering above the front yard like a bait ball of feeder fish. Unfortunately for them, they were swarming directly in the approach path the barn swallows use to get to their nest on my front porch.

The air was full of flashing wings zooming in and out like dolphins taking out the bait ball, right outside my front window. 

And Ashbutt-cat in the windowsill was losing his everloving fluffy little mind...

It did not get better when I opened the window so he could hear the excited twittering of birds maintaining comms for situational awareness and coordination. No, it got worse. Much worse.
