What is the story re male bower birds? Is there only one to service say, half a dozed females. We have plenty of green females but only see the black male on the odd occasion.

Bower birds – I think generally there’s only one male but get the impression like humans, the odd male from outside the territory tries to lure females too. Green ones can be females or might also be young males yet to fully colour up.
