Black Swan grooming
Early in the morning, a Black Swan was grooming.
In the foreground, a Pacific Black Duck still sleeps.
Common name: Black Swan

Pretty but ew: Snail Parasitic Blowfly
I came across a large, pretty fly yesterday afternoon:
It’s a Snail Parasitic Blowfly (Amenia), found on the east coast of Australia. It has an orange head with large brown eyes outlined in white — almost as if it’s wearing sunglasses. Its body is mostly black, with turquoise, green, and purple patches and white spots. The wings are transparent.
Unlike other blowflies, this one doesn’t lay eggs or maggots in dead flesh. Instead, it lays its live larvae onto the shells of snails. The larvae then feed off the snail. The adult flies feed on nectar, helping to pollinate flowers.
There are many different types of blowfly, not all of them as pretty as this one. Evidently the name “blowfly” comes from Shakespearean times: when flies laid eggs on meat and maggots emerged, the meat was called “fly blown”.
Second sighting of a Noisy Friarbird
This is only the second time I’ve seen a Noisy Friarbird. We’d stopped at a picnic area in the Blue Mountains for a quick snack and a swallow of coffee from our thermos. I noticed this rather unprepossessing bird peering at me from a Banksia tree:
The bird was supping the nectar of the Banksia flowers, while checking for danger from above or below at regular intervals.
Noisy Friarbirds have a weird bump at the top of their beaks. It’s not visible in the photos, but you can see it in the video below, when the bird turns its head. The video shows the bird moving from branch to branch, pushing its beak into the flower heads. It’s probably taking insects from between the sticky tepals that make up the flower head. At one stage, I saw the bird grab a passing insect from the air too.
Common name: Noisy Friarbird
Scientific name: Philemon corniculatus
Approximate length: 30-35 cm
Date spotted: 20 January 2024 (summer)
Location: Pierces Pass Picnic Area, Blue Mountains, New South Wales, Australia: 33°34’13.2″S 150°20’17.0″E
Currawong youngsters with Avian Pox (plus a bonus cicada story)
A couple of young Pied Currawongs have been making quite a racket in our neighbourhood recently. I was puzzled and concerned when I noticed that one of them had red swellings around its eyes and an unhealthy-looking bump on top of its beak.
Aside from being unsightly, though, the swellings don’t seem to bother the youngster much. For wont of a better name, let’s call this one Youngster 1. The bird is quite lively and curious, and feeding well.
Here’s Youngster 1 hiding in the shade, awaiting its next feed:
The other young Currawong, Youngster 2, now also has similar swellings, though to a lesser extent:
Here’s Youngster 2 sitting on the same fence as its sibling:
After some research and image comparison, I’ve discovered that these two little ones are most likely suffering from Avian Pox. This condition is caused by a virus that infects many bird species around the world, including currawongs and other Australian birds. It’s usually not too serious, and the birds recover within three to four weeks.
That’s good to know!
Here’s a glimpse of one of the hard-working adult currawongs, taking a breather between feeding runs:
Common name: Pied Currawong
Scientific name: Strepera graculina
Approximate length: 45 cm

A bonus cicada story
A couple of weeks ago, I was filming one of the baby currawongs being fed:
As I was filming a bit of drama occurred. Alas, I didn’t capture any of it on film, as the action took up the whole sky and went down very fast.
Picture this:
A cicada flies past. Two little Noisy Miners give chase. One of them grabs the cicada and lands on our roof, the other Noisy Miner in close pursuit. A currawong parent thinks, “Ah, perfect for the little one.” It swoops on the Noisy Miners, who both fly away, abandoning the cicada to buzz around on the roof. The currawong grabs the cicada.
Not taking this lightly, the Noisy Miners swoop on the baby currawong, which is minding its own business deep in the foliage. There’s a sudden flurry of activity as the adult currawongs and Noisy Miners swoop noisily around the tree. The baby takes deeper cover under a thick leafy branch. The fuss dies down and everyone goes about their business.
I don’t know what happened to the cicada.
Koel cuckoo wearing the midnight
The Koel cuckoos are back! They migrate to our region of eastern Australia in spring, and go back up north in autumn. You know they’re there because of their loud call: coo-eee, coo-ee. It’s less often that you manage to see one, as they tend to stay high up in the trees and make use of the foliage to hide from other birds.
This male Koel spent a few minutes in a relatively exposed position on the street where I live:
The males are entirely black, with bright red eyes and a pale beak. Like other cuckoos, the females lay their eggs in the nests of other birds (mostly wattle birds and friar birds). The cuckoo then abandons the egg and leaves it up to the foster parents to bring up the chick.
My earlier posts name this bird as a Common Koel (Eudynamys scolopacea). I’ve discovered recently that Koel cuckoos were recently reclassified as Pacific Koels (Eudynamys orientalis).
Common name: Pacific Koel or Eastern Koel
Scientific name: Eudynamys orientalis (was scolopacea)
Approximate length: 45 cm
Date spotted: 19 January 2024 (summer)
Location: Allambie Heights (north of Sydney) New South Wales, Australia
Water Dragon lurking under water (mostly)
Australian Water Dragons (Intellagama lesueurii) are large dragon lizards, reaching a length of more than two metres. You’ll often spot them close to creeks and other bodies of water (hence the name, Water Dragon). Sometimes, you’ll see them actually in the water:
They can stay under water for an hour before coming up to breathe! From a distance, their heads are easy to mistake for a piece of log sticking up. As you draw closer, the rest of the body becomes clearer. This is a different dragon in a nearby spot:
They’re completely at home on the land too. When you approach them, they tend to stay still, pretending to be a tree stump, until you get too close.
Water Dragons eat insects, fruit, and flowers.
A few days ago, I came across a Water Dragon that had spotted a piece of litter (a wet tissue or picnic wipe) and was nosing it when I came along. The video shows the dragon’s characteristic side-to-side gait as it moves away from the litter. (I picked up the litter and took it away.)
Magpie-lark nest with chicks
A couple of days ago, I spotted a Magpie-lark having a quick cicada snack. Today, back in the same area of Manly Dam, there was more activity in the Magpie-lark community. It turns out that the birds have a nest nearby, and the adults are busily feeding the chicks.
In this video, the chicks’ heads pop up when the adult arrives to feed them. When the adult leaves, the babies stretch the necks, begging for more.
As you can tell, the nest was quite far away from my vantage point, and my camera’s zooming powers are stretched to the utmost. Still, you can see what’s happening.
Here’s a still shot of the nest with an adult Magpie-lark peering down into it. The adult is a female, as it has a white throat. You can see the white underbelly of the bird towards the left, the black wings above, and then, on the right of the branch, the black-and-white head with the bird’s eye just above the rim of the nest:
Gathering food and feeding babies is hard work. The adults often take a breather within sight of the nest, but out of sight of the babies, so that the babies don’t squawk for food. Here’s a male adult (black throat) at top right of the photo, with the nest near the bottom left:
Here’s a closeup of the adult taking a breather:
Common name: Magpie-lark, also called a Peewee or a Mudlark
Scientific name: Grallina cyanoleuca

Magpie-lark eating a cicada
Magpie-larks are quite striking to look at, with their clear black-and-white markings and their strangely light-coloured eyes. This one caught my attention because it had captured a large insect and was making a good meal of it. The insect is an interesting yellowish pink colour. I think it’s a cicada, most likely the yellow variation of a Green Grocer cicada:
The name Magpie-lark is rather confusing. This bird isn’t a magpie or a lark. I guess the “magpie” part of the name comes from the black and white colouring. I don’t know where the “lark” part comes from.
Evidently Magpie-larks, like their namesake magpies, do swoop at humans to protect their territory. Luckily that hasn’t happened to me yet.
This bird is a male. It has a black throat, whereas the female has a white throat.
Common name: Magpie-lark, also called a Peewee or a Mudlark

Oriental Dollarbird surveying the world
It’s been a while since I last managed to photograph a Dollarbird. They tend to spend their time very high up on tall trees or poles, silhouetted against the harsh Australian sky. It was a delight to see one a little lower down in a bushy wetland.
Oriental Dollarbirds are migratory. We see them near Sydney, on the east coast of Australia, in the summer months. They spend the winter up north, in New Guinea and surrounding islands.
They’re quite pretty when you see them up close, dark with a blue-green sheen on their feathers. Their large heads tend to make them look cute and cuddly. They also have a gently curved beak, with the tip outlined in black , which adds a touch of nobility.
The bird changed position, and we can now see the blue-green colouring on its back too:
Common name: Dollarbird
