Robin and BlueTit sharing a bath

One of our resident Robin's and a baby blue tit share a bath on a warm sunny 1st day of September evening.
It was truly heartwarming to see this spectacle outside in our garden this evening. Some will.know that Robin's are very territorial birds, I regularly see conflict in the garden where we have several Robin's, some even from the same family competing and fighting for food.
So....... It appears that Robin's are only territorial (and vicious) with their own . As can be seen in the video the wee blue tit and Robin got along just fine 🙂
