To feather one’s nest
On my writing blog I have been writing about idioms. One recently posted article looked at an idiom with a birding theme.
This Week’s Idiom
To feather one’s nest
or
To feather one’s own nest
Origin
This idiom obviously comes from the practice of many birds to gather feathers to add to their nest in order to make it more comfortable for themselves while incubating the eggs and then warmer for the chicks once hatched. It has been suggested that some birds actually pluck their own feathers to add to the nest. I’ve never witnessed this in thirty years of birding but it could well be the case. More likely is the gathering of feathers left lying around after a bird dies, or is killed, or from the empty nests of other birds.
Meanings
The applied use of this idiom in common speech and in writing implies that the person being spoken of is gathering financial gain for himself at the expense of others, usually in a dishonest way. So to say that “Peter was feathering his own nest at the company’s expense†is to say that he was perhaps embezzling company funds.
It could also be applied to the misplaced motivation for an action. For example, “Susan only wanted to become a member of parliament to feather her own nest.â€Â
Mallee Fowl – the Incubator Bird

In yesterday’s post I highlighted seeing six Mallee Fowl in a ten minute period one exciting day last year. This almost doubled the total number of this species I had seen in over thirty years of birding. Previous to that eventful day I had seen seven individual birds on five different occasions. (On two of these occasions I saw two birds at the same time.)
Mallee Fowl – Leipoa ocellata
Other names for the Mallee Fowl include Lowan, Incubator Bird and Malleehen. It looks like a smallish turkey and ranges in size from 55 to 61 centimetres in length. It is sparsely distributed throughout south western Western Australia, southern parts of South Australia, northern Victoria and south western New South Wales where suitable habitat remains.
Habitat
The Mallee Fowl has a preference for mallee scrub and eucalypt woodland habitats. Over the last century large tracts of this type of habitat have been cleared for cereal production and sheep grazing. The Mallee Fowl has been slow to adapt to these changes and is now extinct in some regions of its former range, and highly endangered in other areas. The widespread occurrence of the introduced fox has also had a devastating impact on the population.

Nesting
Perhaps the most unusual feature of this species is its nesting habits. The Mallee Fowl is one of three mound nesting species in Australia. The male makes a nesting mound of earth, leaves, twigs and bark from nearby trees and bushes. These he scrapes together into a cone shaped mound. The rotting vegetation causes the mound temperature to rise, just like in a compost heap.
Eggs
The male maintains the internal temperature at about 33 degrees C while eggs are in the mound. The male excavates a hole each time the female comes to lay an egg, usually at intervals of 2 to 14 days. During the breeding season, which stretches from September to April, the female can lay anything from 5 to 33 eggs. Once laid, the male refills the hole and continues to monitor the temperature of the mound on a daily basis.

Nest Mounds
The mound can vary in size from about 2 to 5 metres in diameter and up to 1.5 metres high. In my searches through Ferries-McDonald Conservation Park some 20km SW of where I live I have found seven of these mounds, some still in active use. I have even sat quietly for many hours near a nest hoping to see the birds – to no avail. Finding the nests seems easier than finding the birds!
Chicks
When the chicks eventually hatch – often after more than 7 weeks – they struggle through the sand of the mound to the surface. This struggle can take hours. They then run off rapidly into the surrounding bush. They are not tended by the adults at all but are left to fend for themselves. The chicks can fly a few hours after hatching.
Amazing Bird
The Mallee Fowl is indeed an amazing bird in its habits and nesting methods. Its status is a major concern. The local zoo, Monarto Zoological Park used to have a special recovery programme. The keepers were given special permission to remove eggs from mounds in the district and incubate these eggs artificially. The chicks were raised by hand and released back into the wild. Some were fitted with radio transmitters and tracked. Most were taken by foxes within days of their release. Farmers in the district often have a baiting programme to kill the foxes (because they kill their lambs) but there are so many the Mallee Fowl is still extremely vulnerable.
I haven’t heard in recent years whether the zoo is still pursuing this breeding and conservation programme. There is currently no information in the conservation section of the zoo’s web page.

Common Blackbirds

Common Blackbird (male)
Common Blackbirds are an introduced species in Australia. Their range here is south of a line from Sydney in NSW to Port Lincoln in South Australia and they are found throughout South Eastern Australia, including large parts of Victoria and Tasmania. They are particularly found in parks and gardens where they enjoy scratching around in the leaf litter and mulch for their food. Many gardeners despise the Common Blackbird for their untidy habit of flicking bark, leaves, mulch and sticks on to their nice, neat garden paths.
Beautiful Songbird
The Blackbird may be an introduced species, it may have untidy eating habits but this is more than made up for by its beautiful song. There are few birds in Australia that can match the song of a Blackbird singing in the late winter or spring evenings. It fills the air with a rich melodic harmony.
Breeding
We didn’t have any resident Blackbirds in our garden here on the outskirts of Murray Bridge South Australia until a few years ago. The occasional visitor, yes, but not resident. Now they have moved in and have started breeding. Several times they have used an unusual nesting spot. They fly into a shed in my wife’s nursery through a small gap above the door. They then proceed to make a bowl shaped nest in one of the many empty plant pots we store in the shed. How lovely and cosy – out of the cold, the wind and the rain.

Photos
Despite them now being resident I find that “our” blackbirds are quite timid and are rather camera shy. It was with great delight that today I have been able to take some close up shots of both the male and the female (she is a dull brown colour) fossicking for beetles and worms just outside our sunroom window. This makes a perfect bird hide for photography.
