Fairies at the bottom of the garden

Superb Fairy-wrens are beautiful birds and this week I’ve been watching and photographing them in the garden. They move rapidly, hopping and darting hither and thither (what a strange word) as they forage on open ground and in low shrubs for arthropods such as insects, grubs, caterpillars and spiders. I spent most time with a small group of three fairy-wrens; one female with two non-breeding males – well, that’s what they are supposed to be but clearly they haven’t read the same books I have.

What a handsome boy! I can tell he is one of last year’s hatchlings from the colour of his feathers and bill; it’s exciting to see him as we lost at least one nest due to excessive heat. All juvenile Superb Fairy-wrens hatch with brown bills but males’ bills turn black during their first winter. The bird in the image above has a bill which is in the process of changing colour; the base is brown while the tip is black. Most of his plumage is typical of juveniles of either gender but his tail is becoming blue and looked exquisite in the early morning light. He will develop the bright blue feathers indicative of male Superb Fairy-wrens during his first breeding season: at the moment he is, according to the text books anyway, a non-breeding male.

The image above shows the second non-breeding male. His bill is black, his tail is blue but the rest of his colouring is typical of female and juvenile Superb Fairy-wrens: brown above with lighter underparts. The strange pose in the image was his reaction to a odd sound in the undergrowth, it was funny to see him puff himself up to such a scary size.

Along with the brown colouring above and lighter underparts female Superb Fairy-wrens have brown bills, brown eye-rings and brown lores; lores are the area between the bill and the eye. The female above was busy foraging along with the two juvenile males.

As the female perched on a branch I pressed the shutter button and took a series of three images on continuous high-speed shooting. In the first image she is lifting her tail, in the second image the ‘non-breeding’ male mates with her and by the third image, two one-hundredths of a second later, it’s all over. I’m not positive which of the non-breeding males it is but it may be the juvenile as I can see brown colouring near his eye and his bill appears brownish when I enlarge the image in Lightroom.

The female, above, seemed a bit dazed after the encounter but their promiscuity has been well-documented. Fairy-wrens have a fascinating social life which is not at all how it appears. The male that seems to rule the roost has rarely fathered the brood that he helps to raise. Female Superb Fairy-wrens sneak away during the night to visit neighbouring territories for a pre-dawn liaison with the dominant male. There is a breeding male in my garden at the moment with a larger group of fairy-wrens. His plumage is the bright blue and black typical of breeding males, which can be seen in several lirralirra posts including Wrens, raven and Gang-gang Cockatoos and Superb Fairy-wrens. I’m very interested in the behaviour I witnessed this week and am wondering if the three wrens have been expelled from the larger group, or if there is another explanation. If anyone has ideas I would be pleased to hear from you.

Superb Fairy-wrens build their nests at or near ground level and because of this their tiny broods are particularly vulnerable to predation by cats. Their numbers have declined in urban areas but I am hopeful that as the number of responsible cat owners increases the fairy-wrens may be able to re-establish themselves in some areas. Many cat owners now ensure that their cats are kept inside at all times or are confined in enclosures, some of which are elaborately designed with direct access from the house. These measures not only help decrease the estimated almost one million birds killed by cats each year but also reduce injuries to the cats themselves from fighting, foxes and traffic as well as decreasing the likelihood of them coming into contact with dangerous feline illnesses.

Hopefully in the coming weeks there will be fledgling fairy-wrens in my garden, and hopefully I’ll be able to get some images to share.

Happy birding, Kim
