Bird lightly bumping into window?
We've had a bird feeder up for the past couple months. There's usually tons of birds at it all day every day. However, today the only bird that is coming up to it is one chickadee who keeps flying and gently bumping the window and staring inside. This has never happened before and it seems like its trying to get in or get our attention. I went outside to see if it had a nest and needed help but I couldn't find anything. I'm not sure what to do but i want to help it.
