The birds circle each other uneasily. The newcomer is the bird on the
bottom right of this picture. The question is - what sex is this bird?
From the image we saw outside with its wide white head band, we thought it must be a male. Now it is inside and we can observe it more closely, it could be of either sex.

The circling continues. The newcomer is now at the top of the picture
and the original male, who is looking more aggressive each second, is at the
bottom.
9:43:19
Suddenly, the newcomer turns its back on the male. Not the thing to do
if you are about to have a fight!
However, if you are a female, ...?
9:43:20
Here she (its now clear that fighting is the last thing on this bird's mind)
turns a bit more and the male rears up over her.
