We have a blue tit building its nest at the moment and we observed some mysterious behaviour, which I don't know if it is courtship or defence. I hope someone may shed some light on this.
Yesterday evening (video), the nesting blue tit entered the box. A while later another one came with its wings lowered and seemed to be "begging" outside the box. Inside the box (video), the nesting one "bit into the air" even if it didn't see the other one later. It didn't look aggressive as it didn't spread its tail or made any noise. I am not sure if the one side was the male as it looks different from the male that used to come.
A while later (video), the blue tit outside was still lowering its wings and seemed to be begging outside the nest box. You can see the nesting one's behaviour (video).
This evening, we saw the nesting blue tit "attacking" the one outside (video). Is this really an attack?
