I thought "You know, I bet I'm dreaming this. However, just in case..." and I went looking for my ruler so that I could measure this bug. I found the ruler, and the bug was two and a half inches long when I measured it (it had been at least six while flying, which made me deeply suspicious.)
Then these ducks came walking across the deck. They were brown ducks, but they were molting, and their body feathers were coming in huge and poofy and the violent carrot orange of a drag-queen's feather boa. "Orange ducks!" I thought. "Surely there can't be many of them in the field guide!" On the back of each head was a small white marking. I found my Sibley guide and began flipping through it, looking frantically for orange ducks with brown heads and a white mark on back of their head. "Gotta remember the field marks, gotta remember the field marks..."
And then I woke up, without ever locating the ducks in the guide. But I suspect I may have birds on the brain.
