Hee, hee!!!! I don't think the neighbors would appreciate that, peanut butter smeared on top of that post! Sometimes people set things down on them temporarily while getting things in-and-out of their cars or if someone has lost something and it is found, the finder will set it on top of one of the posts. There's a pretty floral cloth mask sitting on one of the posts now, actually, that someone must've dropped while coming-or-going...... I always keep my mask on, at least around my neck, until I've gotten in the house and can throw it into my trashcan.
I swear we have or had a nest somewhere around the building, as there are just too many sparrows hanging around here, squawking up a racket! Huh, right now I've got three of 'em dining on the birdseed I've put out on my deck!
