Box3 is still being visited. However, this looks a different bird to the one I pictured earlier. Its head feathers are very smooth. I think it must be a female.
Something has startled her. See her head feathers are lifted up.
Half a minute later and she is still alert and on guard!
That settles it - she is a female.
Box1 is still being visited - but that is all that can be said of it.
Nearly all our birds seem fascinated by what is up at the top of the box.
Definitely very curious!
