These are light and airy to allow them to easily lift them above the body which they use for mating displays.

Multiple males will gather in a single location known as a lek site. At the lek site multiple males will sit on a tree branch and display to the females. Their display involves raising the tail feathers over their head and back, hopping along a branch with the head lowered or raised and extending their wings.

The males decide among themselves who made the best display and these birds occupy the most prominent perch. Females then target these males as the ones to mate with. He will display a final time for her prior to mating. A male may mate with multiple females throughout the breeding season.

Following this the male ends his parental involvement and the female begins to build her nest. The nest is formed from leaves, ferns, orchids, twigs and moss and is shaped like a cup.

In to the nest the female will deposit 1-2 pink colored eggs. These are incubated for 18 days. At birth they have no feathers and the eyes are closed.

Young are in the nest for 17-23 days before fledging. They may remain with the parents for a longer period than this.
