In days long past this observation would have been commonplace, a Wedge-tailed Eagle perched atop a Buloke.
Both are iconic species, but sadly, such a sight is a rarity in these present times.
The Buloke is emblematic of the plains country, easily taken, slow to return.
Bunjil, the Wedge-tailed Eagle, is of special significance to Indigenous Australians, especially the Dja Dja Wurrung People of central Victoria.
Bunjil is the creator being who bestows Dja Dja Wurrung People with the laws and ceremonies that ensure the continuation of life. Dja Dja Wurrung People know Mindye the Giant Serpent as the keeper and enforcer of Bunjil’s law.

This Grey Teal duckling was all on its lonesome, paddling happily on a small dam on the plains … no sign of its parents or siblings … I don’t like its prospects.

Over the past week I’ve heard Fan-tailed Cuckoo, Sacred Kingfisher and Rainbow Bee-eater, all three are spring migrants about to head north, as well as Pied Currawongs, autumn migrants, arriving from the hills in good numbers. A single Swift Parrot was also spotted departing the backyard Yellow Gums, chased by a Red Wattlebird. ‘Swifties’ are back from Tasmania and I’m hoping to have a good look for them over the weekend in the Muckleford bush.
Last evening on a drive across the plains I came across a pair of Blue-winged Parrots, feeding on seeding grasses. This species is always a delight to encounter. It arrives in small flocks during autumn, after breeding further south, either in Tasmania or coastal forests in Victoria. More commonly seen on the plains country it also can be found in box-ironbark forests and woodlands.
Earlier I’d come across a young Wedge-tailed Eagle, standing aside a road-killed Red Fox. Quite a sight as it departed with ravens in pursuit.

The Brown Falcon can at times baffle even the experienced birdwatcher.
They come in a variety of colour forms, from rich chocolate brown to almost white. Across the continent dark form individuals are more common in the tropics, while in arid regions the predominant form is washed with rufous. Apparently all individuals tend to get paler with age and the bare parts (legs, cere and orbital skin) becomes yellow over time.
Two individuals are pictured here. The first, a dark form, is possibly a young bird, going by the rufous wash around the head and blue cere and orbital skin. In the first image you can see it’s clasping a bundle of grass, the result of a ‘prey-pounce’, moments earlier.
The second individual is a light form, possibly an older female.

Just ‘closing the loop’ on Spotted Harrier observations on the Moolort Plains.
The three youngsters featured earlier this month have been honing their flying and hunting skills. Spotted Harriers not fast but they are very acrobatic and can wheel and dive rapidly when required. They are also adept at chasing and hunting down prey; such as small birds, reptiles and insects, on the ground.
Typical harrier hunting behaviour involves low-level quartering over cereal crops and stubble, interrupted (when food is abundant) by regular short descents to the earth to snatch their prey. The initial strike is not always successful and the raptor is quite happy to chase down its quarry ‘on foot’.
The youngsters were having a terrific time practising their acrobatics over the sun-drenched paddocks, while a little later I watched one of the juveniles prancing in the shade emulating the ground-foraging behaviour of the parents … there was no obvious prey in sight but it won’t be long before the technique is more serious.

Juvenile harrier ground hunting
Hunting on the wing
In recent weeks I’ve enjoyed some time with juvenile Spotted Harriers on the Moolort Plains.
A number of times now while observing the young harriers the peace has been disturbed by the sudden arrival of a falcon, on one occasion a Black Falcon and twice by a Peregrine. Each time the arrival of the raptor was announced by a burst of alarm calls from the local residents and some rapid and haphazard scattering of nearby galahs and corellas.
Galahs are a common prey item of the Peregrine Falcon, as evidenced by my observation near the Moolort Silos. I disturbed the falcon as it stood over its kill in the middle of the road. It returned some minutes later to drag the unfortunate Galah some distance (allowing a quick and blurry image) before departing to perch in a distant tree. Both of these falcon species are extraordinary flying machines, the Peregrine is faster by a reasonable margin, whereas the Black Falcon exudes power and speed on the wing.

As I suspected the Spotted Harrier clan on the plains includes no less than three juveniles – a wonderful result.
The youngsters are doing well it seems , chasing food on the ground and from the air. The adults have been absent during my visits … I suspect they are watching their offspring and the photographer from a distance.
Spotted Harriers lay two to four eggs in a clutch, although to raise three healthy juveniles is, I reckon, a little unusual and a sign of an abundance of food this season.

That ‘owl-like’ face!
Back before Xmas I reported a pair of adult Spotted Harriers hunting on the Moolort Plains. In a pleasing development it looks like this pair has raised two, and possibly a third, juvenile.
Young Spotted Harriers have quite different plumage to the adults, rich buff is the overall impression. They do, however, share the same distinctive features as their parents that makes them instantly recognisable – long slender legs, extended narrow wings, barring on the tail and flight feathers and the owl-like facial disc.

On a drive across the plains earlier in the week a flash of crimson caught my eye, enough to cause me to stop and linger for a while amongst a roadside stand of Bulokes.
The crimson was from Buloke Mistletoe Amyema linophylla, a rare parasite that grows on only two hosts, Buloke Allocasuarina luehmannii and Belah Casuarina pauper.
Buloke Mistletoe is only found on a small proportion, perhaps less than 5%, of the Buloke growing on the plains. The host is the signature tree of Buloke woodland, once a widespread and common ecosystem, now extensively cleared and consequently threatened. Buloke woodlands of the Murray Darling and Riverina are of major conservation importance.
As I admired the splendid mistletoe a flock of Yellow Thornbills appeared above me. Also known as the Little Thornbill, the party foraged happily for a while before moving on.
I’m pleased that I bothered to stop.

A late afternoon jaunt across the plains has become something of a ritual – the week is not complete without at least one circuit. Yesterday afternoon was looking like a largely fruitless excursion until I turned the car for home.
A large raptor caught my eye, hovering low over a ripening cereal crop. Instantly recognisable as a Spotted Harrier Circus assimilis, it hunted in typical fashion for 15 minutes or so as I watched in awe from the roadside. An absolutely gorgeous raptor, the Spotted Harrier feeds on small birds, mammals such as mice and rabbits, as well as insects. The harrier disturbed numerous small birds, including Horsefield’s Bushlarks and Australian Pipits, as it wheeled low in small circles – dropping to the ground regularly in pursuit of a meal. This species will successfully chase its prey on the ground as well as via a direct pounce. As I continued my homeward journey its mate was encountered a little further along – this individual was significantly smaller, confirming that the first bird was a female and the second a male. Spotted Harriers nest regularly on the plains, raising their young at this time of year when food is most abundant.
