They pygmy mirror bird is called such because of it's dual sets of wings and tails. They live in large flocks lead by females. Their iridescent feathers are much sought after for their appearance, and also because they are very soft.
The color of a pygmy mirror bird ranges from purple to teal, with the females always being a lighter hue.
