Series: Two Carolina Wren's mating after a quite impressive song and dance by the male.
According to Bird Houses 101, http://www.birdhouses101.com/Carolina-Wr..., "Carolina wrens are monogamous birds. Though not much is known about their mating habits it is reported that most Carolina wrens are monogamous not just for one breeding season but actually pair for life. To start of the mating process the male Carolina wrens put on an elaborate show to attract a female bird. It preens and hops around showing off its feathers and tail. As soon as a female wren comes close enough the male wren starts courting the female bird by circling around the bird and continuing on hopping in a stiff pattern. While doing this it puffs out its feathers and fans its tail as it tries to impress the female Carolina wren. Although not that common a sight, it has been reported that some male wrens even fetch and bring female wrens an offering of food while courting the female bird. Once the female bird is attracted to the male wren, they mate and is then bonded for life."
