Hi Murph
Wish I'd gotten better footage.
Almost all of what you see in the video are dragonflies. The birds were higher up. I tried to move the camera up to get the birds but the lighting was bright.
It took me forever to figure out what they were after until i looked down at the ground. I'm not exaggerating .. completely covered with some type of red insect with wings and they were everywhere even on the other side of my house. Maybe that's what the birds were after too. I'm not sure if birds eat dragonflies? prolly so. Mostly gulls. I do live by a lake but I have Never seen so many of anything like that. Ick.
I took a couple pics of the ants - I'll see if i can find them
