My home office area is set up in a corner of the den where two windows meet and allow sunlight to pour in and brighten the room. I enjoy looking out those windows while I'm pondering a blog post idea, deciding the best way to structure a sentence, or editing photos to share. (I pay bills in the same spot, but that process doesn't involve much restorative window gazing.)
Lately, for some reason, sparrow-sized birds have been flying up and attaching themselves to the window screens. They'll hang there for a moment then hop across to a different spot on the screen or maybe fly away altogether, only to return a few minutes later. Sometimes more than one bird will land on the screen, one right after the other. Most of them eventually move upward toward the corner of the roof and out of my line of vision. I don't know why. I've looked twice and can't detect any sign of a nest up there.
The birds scratching on the screen sound very much like mice inside a wall, so the first time I heard that scratching I was relieved to look up and see a bird. Actually, because they are backlighted by the glaring sun, I see only their dark silhouettes--black, bird-shaped blobs. I can't identify what kind of birds they are.
As much as I like our fine feathered friends in general, about the only thing I can say for certain about these particular ones is they sure have a way of knocking an idea right out of my head.
