From the Horse's Mouth

There was a mini-mart on the main drag thru town, and the power line outside said site was always absolutely covered with perched birds.

We finally realized that Radagast worked there incognito.

Then the store closed and the birds went away.

We haven't figured out where Radagast is now.

I have a great thematically similar photo, higher bird density, that I did on B&W film some 10-15 years ago, apparently I never uploaded it. I'll have to take care of that later and post it.
