Saving grassy woodland is not just a matter of saving and replanting the trees.
When protecting the whole environment of the grassy woodland (rather than just
the woodland component) it is just as important to protect and regenerate the
native grassland beneath the trees.
Many species of wildlife are dependant upon woodland and grassy woodland for
their survival. Unfortunately these two habitats, once so widespread in the
region to the west of Melbourne, are now greatly diminished and endangered, and
the remnants are fast disappearing. Consequently, the wildlife species that
depend upon these habitats are also threatened and endangered.
Diamond Firetail Finch
One such species that depends upon grassy woodlands for its continued survival
is the Diamond Firetail Finch. This is a strikingly beautiful bird that is
unfortunately threatened (as is its habitat). We are fortunate in having numbers
of Diamond Firetails (among many other species) in Pinkerton & Bush's Paddock.
The Australian Bush Heritage Fund recently published an article on the Diamond
Firetail in its magazine 'Bush Heritage News’:
“Diamond Firetail: Conservation status: near threatened, nationally
Diamond Firetails live in the eucalypt-dominated grassy woodlands of
south-eastern Australia. Most of these habitats have been cleared or severely
modified, making them unsuitable for the birds.
The firetails are also disappearing from small areas of remnant grassy woodland
One of the key factors causing the decline of the firetails is thought to be the
replacement of native grasses with introduced pasture grass. Where grazing
pressure from stock is high, the grasses also fail to set seed, thus depriving
the firetails of their most important food.”

The article refers to just one species of bird that is becoming nationally
threatened. However, this applies to other species of wildlife also. It is
imperative that the few surviving remnants of woodlands and grassy woodlands be
protected.
Robins
Among the seasonal migrants are the robins. These are a spectacular sight,
especially as they visit during the darker months of autumn and winter The male
Scarlet Robin is unmistakeable, with its bright scarlet breast contrasting
boldly with its back of velvet black, usually seen accompanied by several brown
coloured female partners. They are a common sight here during the colder months.
Occasionally its rarer relative, the Flame Robin is also seen, but this has a
flame-red breast and a slatey-grey back. Unfortunately, robins are declining in
numbers, probably due to habitat loss.
Blue Wren
Fortunately the beautiful Blue Wren, well known and loved by everyone, is common
here all year round, as is the similar sized Yellow-tailed Thornbill (with its
more subdued brownish plumage and bright yellow rump). Many of the smaller birds
such as these depend on low bushes (not just large trees) in which to find
shelter for nesting and protection.
Parrots
Parrots are a prominent feature of the woodlands, finding nesting sites in the
many hollow trees, and in spring they are especially conspicuous, squabbling
noisily with each other (and with the ever present exotic mynahs and starlings)
over nest sites. Eastern Rosellas and Red-rumped Parrots are commonly seen, and
Galahs are also a common sight, with White Cockatoos and Corellas often seen
flying overhead. The abundance of these parrots often causes us to overlook
their brilliant colours.
Other birds
Often seen flying overhead are the majestic Wedge-tailed Eagles, as they search
the ground below for rabbits, their main source of food. Whistling Kites and
Little Eagles similarly soar above the grasslands and woodlands, also on the
hunt for rabbits. Other hawks, large and small, fly among and above the trees,
hunting for prey. Kestrels and Black-shouldered Kites hover over the grassland
looking for insects and small birds, while falcons course the skies at great
speed with long pointed wings, hunting larger birds. The occasional
White-bellied Sea-eagle is sometimes seen flying over the adjacent Western Water
treatment plant, and the nearby Melton Reservoir. This surprising visitor is
similar to a Wedge-tailed Eagle, but has striking black & white coloration, and
no long wedge-shaped tail.
Many other species of birds make their homes in Pinkerton & Bushes Paddock. Some live here permanently, while others are visitors only, migrating from other places at various times of the year. The Bird Observation & Conservation Australia (BOCA) conduct regular surveys of birds, and maintain a list of the birds found here, updating it at regular intervals.
The range of habitats in and around Pinkerton & Bush's Paddock ensures a healthy
population of native birds. The grassy woodland itself adjoins a sizeable
remnant of restored native grassland, while itself surrounded by farmland and
grazing land. The nearby Werribee River corridor, separated from the woodlands
by the Western Water treatment plants (with its large collection of treatment
ponds) also ensures a healthy diversity of bird life in and around these two
reserves.
