What you can't see in the photo is that there was a bush fire burning in the vicinity, billowing smoke into the clear sky, causing the light to change from its ordinary mid-day bright white into a soft orange hue. Normally a peahen's feathers are pretty dull, lacking colour, but on this day the filtered light transformed her plumage to be the golden brown colour that it is in this photo.

An alternate theory, to a "first date", is her alleged suitor wasn't actually a suitor at all... perhaps he was simply in awe of (and probably jealous of) her unusually-pretty plumage!
