Window screen, that is. Nelo enjoys the view. I just wish I could have caught the squirrel while he was hanging spread eagle between the two things, staring into the window at us. Priceless! But I missed it.
@seattlite Thanks, Gloria. I was pleased to catch Nelo and the squirrel at the same time. She (Nelo) is not the best model -- moves around too much. Someday I'm going to look into whether we can replace the screen with another layer of glass. There's only so much I want to do with shots of birds or squirrels that are overlaid with window screen pattern.
