Another female visits

This morning the box was visited again and I saw the same thing as yesterday: wriggling/ wing fanning and in the end she picks up some of the wood shavings from the box and flies out.

I managed to see where the bird was going with the wood shavings: she flew into a tree about 7 meters away and dropped them. So it appears she is not interested in the material itself but just wants to remove it from the box.

One of the questions I have: is this the same female that visited yesterday? Well, it is very difficult to see because the birds look so similar and much depends on the light and posture, but based on some frame to frame comparison of the video I think they are different birds.
