Great tit evaluates the box!

Just three hours after the blue tit threw an “invader” out of “his” box, he is faced with a much bigger threat. A great tit is now showing a serious interest in this potential nest site!

A pair of great tits arrived and the female entered the box. She was doing all the expected stuff like pecking the floor, pecking the walls and pecking around the entrance as well as performing these typical “wriggles” with the wings spread out.

While all this was happening, I saw the blue tit who probably thought he already owned the box flying around nervously, sitting on the roof of the box and peeking inside occasionally. However, he didn’t dare to take on the great tit inside the box.

On another subject, I’m still wondering what this posture means. Apparently it is some kind of display because it is always aimed at the opening of the box where the male bird is.

Around 1:29 in the video you can see this posture

Later in the day when the great tit had left there was again a visit of a couple of blue tits that was obviously checking out nest sites. And while I write this (in de evening), a bird is spending the night in the box. Not sure what it is (it’s outside the view of the camera) but I can hear it through the microphone. I suspect it’s a blue tit because a great tit makes more noise when entering, since it hardly fits through the opening! 

So who will take the box (if anyone) is still undecided I guess…
