Australian “Blue Wrens”

Male Splendid Fairy-wren in full breeding plumage at Joondalup

Brightly-coloured male Fairy-wrens in their nuptial plumage can stop many an Australian birder in their tracks. The birds may be tiny but they more than make up for it with showiness. Most familiar are the two “Blue Wrens’ – the Superb Fairy-Wren (Malurus cyaneus) of the east coast and Tasmania, and the Splendid Fairy-wren (Malurus splendens) found across the south-western and more southern central areas.

The male blue wrens are easy to identify in their distinctive breeding plumage, but most male Fairy-wrens are only dressed in their beautiful breeding colours for spring and summer; in autumn they moult back into what is called eclipse plumage – similar to the females at first glance. Separating the females, youngsters and non-breeding males is a bit trickier, requiring a close look at the colour of bills, eye-rings and lores. First year males can be confusing as they show the tan eye ring of the females combined with the black bill of a male, while some of the older males will retain their bright colours for the whole year. Often it is thought that the family groups consist of one male with several females but closer inspection usually reveals some birds to be males in non-breeding plumage.

The blue feathers of the males are iridescent, caused by the particular structure of the barbules of their feathers. Its not hard to see where the Splendid Fairy-wren’s scientific name of splendens (shining) came from. I have often noticed this iridescence when photographing the breeding males – usually the images need the contrast and highlights toned down a bit to prevent the feathers looking plastic. The feature image for this article is a good example – not sure how successful I was. The ear-coverts are often the shiniest feather tract – they are used in face fan displays, which appear to be a territorial behaviour (sometimes seen in response to call playback; phishing is a better option).

      1. Hi Laura, one of the Superb Wrens was captured on a visit to Tassie – awesome place. The others are from Canberra and NSW. But I am based in WA which is where most of my photos are taken.
        Love your wombats pics – one of the best things about Tassie was seeing wombats.

      2. Hi Jennie, your so lucky to live in WA, another favourite place of mine! WA has so many beautiful birds! Look forward to the rest of your photos
