@Larrynic I am answering here so I don’t get moderated talking off topic. It’s great that you have found a bower and that you have several bower birds near you. I find that if I follow the males (black) they usually lead me to the bower because they only add 2-3 sticks at a time. So when I see them go low on the ground to the same place repeatedly, then that will often lead to finding a bower. I would expect most of the adult males to make one, though some may be juveniles. I find that they often build a bower near where people sit.
