	Taxonomy
		Satin bowerbirds are dispersive rather than migratory, and their distribution is unknown due to their discontinuous range (12).
		Satin bowerbirds travel in noisy flocks of up to 100 birds, with a steep ratio of many females to few males (12).
		Bowerbirds also have a circular blood vessel in their irises that changes the brilliant color of their eye during periods of emotion.

	Bowerbird - Wikipedia, the free encyclopedia
		All are small to medium in size and their distribution is centered around the tropical northern part of Australia-New Guinea.
		Their most notable characteristic is the extraordinarily complex behaviour of males, which build a bower to attract mates: a collection of look-alike objects that are carefully collected, sorted, and arranged by colour into spectacular structures, often including some hundreds of shells, leaves, flowers, stones or berries.
		Though bowerbirds have traditionally been regarded as closely related to the birds of paradise, recent DNA-DNA hybridisation studies suggest that while both families are part of the great corvid radiation that took place in or near Australia-New Guinea, the bowerbirds are more distant from the birds of paradise than was once thought.

		In satin bowerbirds there is variation, but usually among mature males the bowers aren't very different, certainly within a specific population.
		Though what I just found with the spotted bowerbirds is that a lot of variation exists within a population in the width of the bower, the way the decorations are displayed, whether it has two walls or three walls, and whether it uses straw and sticks or just sticks.

		I tested the hypothesis that male satin bowerbirds reduce the threat of their courtship displays by modulating their display intensity in response to female crouching.
		These studies with the robot bowerbird showed that female crouching is critical in determining the intensity with which a male can display, and that a male’s display intensity and the rate at which he startles females are critical in affecting his courtship success.
