Great Tits. That’s the ones with a longer tail right? Saw one checking out one of my bird boxes.
Saw a video of a blue tit from first inspection of box to first egg 46 days.
You could be right, but I thought that they might be long tail tits? Not sure great tits have long tails but I'm no expert. Whatever, looks like you may have spring visitors which is lovely.
Great tits have a yellow breast with a dark line in the middle. long tailed tits have a much lighter front almost white. Their tail is often longer than the body.
