Birdie on my bird feeder

Not only are such sightings rare, but I haven't seen two at the one time before. (Unless, of course, it's just one very elastic bird.) I think the problem is that the feeder is too close to my big windows. In a first floor flat, there is little I can do about that. I was hoping that the proof of my new book would be delivered today, but it hasn't arrived. 'It's in the post,' I was assured. Maybe tomorrow?
