Had an awesome visitor accompanying me in the garden...

4. I was driving across a nearby dam a few years ago...

... at dusk, with a nature preserve on either side of it

That's when I saw the silhouette of a bird flying over the dam, and it looked like a pterodactyl to me!

Since that obviously struck me as impossible, I later looked up the birds that frequented that preserve, hoping to learn what might've created such an illusion.

My best guess was a large Great Blue Heron, especially because of the long feathers at the back of their heads.
