The crowd at the bower seems to include not only the mature blue-black male and green female, but also a darker green bird who is doing the bower-minding work too, until shoo-ed off by the black male. I think a male at point of changing plumage. And you will see this bird steal a blue object – we have no idea where that was taken.
Back at my place, of course we are not well organised, we have seen a darker green bird dancing for a lighter green bird at the site of the old bower, now without anything blue on the ground at all. But familiar geography and probably pheromones.
Another unrecorded thing, observed twice: we have a bird bath. Green bird arrives, has a drink, turns 180 degrees, there is movement of anal sphincter, the bird turns and drinks again. We saw no poo. We suspect a dose of pheromone to the water...
In this movie compilation, Matt has added a romantic soundtrack sung by Rebecca Pidgeon.
