Gouldian Finch, Adelaide Zoo

Gouldian Finch, Adelaide Zoo

The above photo of a  Gouldian Finch in an aviary in the Adelaide Zoo, South Australia is not a good one.

Sure – it shows some of the brilliant colours of this magnificent species, but the bird in question would not turn to face me. I had enough problems focussing on the birds through the black wire netting of the aviary, only to add to my angst when the bird would not pose appropriately for me. Nor would any of the other finches in this cage despite waiting a considerable time for them to settle. They were all very flighty and more concerned about flying around than posing for me.

Sigh.

Next time… I hope.

Bush Stone-curlew, Adelaide Zoo

One of the more interesting birds on display in the Adelaide Zoo here in South Australia is this Bush Stone-curlew.

Standing just over half a metre in height it is an imposing bird. This individual wanders around an open enclosure with Pelicans, a variety of ducks and some Cape Barren Geese. I am assuming it has had its wings clipped to keep it from flying off.

Although this species is widespread throughout a large range across Australia, I have yet to see this bird in its natural environment. It is mainly active at night and most observers’ encounters with the species would be only hearing its haunting, far-reaching “weer-loo” call at night.

Malleefowl in the Adelaide Zoo

Malleefowl, Adelaide Zoo

The Malleefowl, a turkey-sized mound building bird of the drier parts of Australia, is a widespread but uncommon bird living in the region where I live. It is primarily a ground dwelling bird, feeding mainly on seeds. The male makes a large 2 to 3 metre wide mound of sand and vegetation like leaves, grass, bark and so on which acts like a compost heap.

The rotting vegetation develops heat which incubates the eggs the female lays and buries in the mound. The male works the mound daily during the summer months, adding or removing soil to regulate the temperature in the egg chamber. Not surprisingly, this bird is also known as the Incubator Bird. In all my years of birding I have only seen about a dozen of this species, but amazingly, I saw 6 in a one hour period.

The bird in the photo above is a captive bird in the Adelaide Zoo.

Spotted Turtledove, Adelaide Zoo

Spotted Turtledove, Adelaide Zoo

The Spotted Turtledove is an introduced bird species in Australia. It has become common in many parts of the country, especially in our cities and larger towns. In some parts it is almost in pest numbers, taking valuable food and nesting materials from native species. Some people find its incessant cooing call to be very annoying, although I sometimes find it to be somewhat soothing – until it goes on for hours!

The bird shown in today’s photo was wandering around in the grounds of the Adelaide Zoo here in South Australia. It wasn’t part of the zoo’s excellent bird collection but was rather taking advantage of food left for animals on display – and food items dropped by careless human visitors.

Murder in the garden

Many people enjoy seeing birds, especially those that visit their gardens. People also enjoy seeing birds in parks and reserves, on the beach or along rivers. They are variously described as “cute”, “pretty”, “delightful”, “wonderful” and many other such “nice” words.

Rarely are they described as gory, or brutal or even dangerous. The stark reality is that while many birds are indeed stunning in their colours, amazing in their survival instincts and quite fascinating in their behaviour, some species do have a gory, brutal (in human terms) side to their lives.

A few days ago I was hanging up the washing on the clothes line – or getting it off – whatever – and there was a sudden noisy kerfuffle in the trees nearby. The various honeyeater species were totally upset – and with good reason. A Collared Sparrow-hawk flew ponderously to a branch nearby, clutching a struggling bird in its talons.

The sparrow-hawk proceeded to gouge chunks of flesh off the hapless bird, feathers scattering in the breeze and all the while the rest of the avian community voiced their disapproval – or fears. I tried to sneak up for a closer look. I quickly dismissed the idea of racing inside to get the camera. It appeared to be a White-plumed Honeyeater being eaten.

This is the reality of life in the raw.  To survive, the sparrow-hawk must eat. One bird’s death means another bird’s survival. In human terms it seems cruel and gory, but this is the way of web of life.

I didn’t get a photo, so I’ve included one below that I took some years ago.
