Male Superb Fairy-wren losing his breeding colours

In late February all but the dominate male moult their breeding colours and start adopting eclipse plumage. They start to regain their breeding colours in early August, and are in full breeding colours by September. F3 Rest Stop Ourimbah 27th Feb 2013

Eclipse male Superb Fairy-wren

During the winter months the eclipse male Superb Fairy-wrens lose all of their breeding colours except the blue tail and have black eye lores. They also have a black bill and dark legs compared to the females. The males will colour in their first year but only for a couple of months. Second and third years are longer and by the fourth year they stay coloured all year. Budgewoi, NSW June 2014.

Female Superb Fairy-wren

The female Superb Fairy-wren has brown eye lores, bill, legs and tail. I suspect this is why many people say they haven't seen any "Blue-Wrens" over winter looking at the above two images. In winter there is one one dominant blue male, the rest are brown.

This probably lead to another common name the "Mormon Wren". The younger males have blue tails and the females have brown tails. This colour change may be for them to be less conspicuous to predators. July 2014 Budgewoi, NSW.
