I've been spending my morning work meeting watching my bird feeders instead of paying attention haha. This morning I saw what looked like a young blue tit, along with a couple of wood pigeons and a beautiful great spotted woodpecker (photo from a few days ago, this one's a regular visitor).
I've got pretty good at identifying all the birds I can see from my window by sight, so I've been trying to learn their songs so I can tell which ones are around even when I can't spot them, which is getting harder now that the leaves have all grown back on the trees. When I hear a great tit close by I know they're going to show up at the feeder any second, so it's also helped me spot them more often.
