Baby Channel-billed Cuckoos fed by Currawongs
Walking along a shady path this morning, I heard a loud caterwauling from above. Two baby Channel-billed Cuckoos sat in the trees, yowling and shaking their wings. A Currawong arrived and fed a piece of meat to one of the cuckoos. Then another Currawong brought food to the second screeching youngster.
Like most cuckoos, Channel-billed Cuckoos lay their eggs in the nests of other birds and leave it to those other birds to hatch the egg and look after the growing chick. These particular cuckoos are very large (around 65 cm from head to tail) and so they need to pick the adoptive parents carefully. Currawongs are the usual choice.
This video shows one of the babies yowling and begging for food from its Currawong adoptive parent:
See how large the baby is in relation to the Currawong who’s looking after it! In the next video, one of the babies attempts to eat a largish morsel of meat that a Currawong has just fed to it:
I’ve never seen two babies together before. I wonder if they both came from the same nest, or if they found each other after leaving their nests?
Here’s a still picture of one of the baby cuckoos:
Being a youngster, its eyes are still light brown. The adult birds have fierce red eyes. They’re magnificently ugly birds.
In the next picture, one of the babies is pointing its beak at the sky, perhaps wondering where its next feed is coming from:
That picture gives a good view of the bird’s large beak and the markings on its back and tail.
One of the things you notice about Channel-billed Cuckoos is the supple way they move their neck and head. Here’s one of the babies leaning forward, in a pose that’s typical of these birds:
Oo-er, you probably wouldn’t want to bump into that bird one dark night. Here’s a picture of both baby cuckoos, looking at each other:
To finish off with, here’s a close up of one of the babies, head and neck only:

Rainbow Lorikeets enjoying our Banksia flowers
One of our Banksia trees has covered itself in blooms. The local Rainbow Lorikeets are delighted. A delighted lorikeet is a noisy lorikeet! In fact, anyone who lives near these birds will tell you that a lorikeet in any type of mood is a noisy creature.
One day was quite breezy. I like this video because of the way the bird hangs on to the Banksia flower as it sways in the wind, and because you get a chance to see the bird’s colourful underside as well as its topside.
Here are a couple of the birds lurking on a nearby tree before making the hop down to the Banksia:
I’m so lucky to have these pretty, chatty little birds dropping in regularly to see what’s what.

Channel-billed Cuckoo laying egg in Currawong nest
This little episode happened in my garden today. It was interesting and exciting to watch!
A cacophany of Noisy Miners and Currawongs drew me out into the garden to see what was up. High in a gum tree were two Channel-billed Cuckoos, being harassed as usual by the other birds. I only managed to get one of the cuckoos into my camera sights. Luckily, it turned out to be the female bird.
Here’s the Channel-billed Cuckoo on the right, with a little Noisy Miner by its side:
In this short video, you can hear the Noisy Miners peeping incessantly. The cuckoo emits a loud, harsh caw and cedes ground:
Next, the local Currawongs join the attack. The musical, bell-like tones are the Currawongs. The cuckoo flinches and utters its harsh croak. Then I noticed that there’s a Currawong nest just below where the cuckoo is sitting!
Like most cuckoos, Channel-billed Cuckoos are parasitic. They don’t build nests of their own. Instead, they look for a likely host (a Currawong does very nicely, thank you) and lay an egg in the chosen host’s nest. The Currawongs take over all parental duties, looking after the egg along with those of their own, then feeding the baby bird.
Channel-billed Cuckoo chicks don’t turf the other chicks out of the nest (many types of cuckoo chicks do) but they do eat a lot, and grow significantly bigger than the Currawong chicks.
Having decided that the neighbourhood is reasonably quiet and safe for a bit, the cuckoo eyes the nest and starts its approach:
Quick as a flash, it hops up into the nest and lays its egg:
Below is a still picture of the Currawong’s nest. I’ll keep an eye on it, in case I can spot the Currawong and cuckoo chicks when they arrive:

Noisy Miner babies
For a couple of weeks, we had the pleasure of hosting a nest of Noisy Miners in our garden. The adults built the nest in a tree fern, right in the hollow where the new fern leaves sprout. This picture shows the tree fern, with the nest and one of the adult birds in attendance:
It’s a good thing that little Noisy Miners grow so fast. A few years ago, some Red Wattle Birds attempted the same thing, and were forced to abandon the nest when the fern leaves pushed it out of place!
This video shows an adult bird feeding the babies:
With Noisy Miners, feeding the little ones is a communal responsibility. You can’t tell which are the parents. We sometimes saw three birds waiting in line with a goody for the growing babies.
In the above video, the adult is regurgitating nectar or other food. Its long, thin tongue flicks out occasionally. In the next video, a bird brings a large green bug and passes it to the babies. I’m not sure if the bug is a mantid or something else. It’s too early in the season for cicadas:
Here’s a still picture of the little ones begging for food:
After a couple of weeks of feeding and fast growing babies, the nest became pretty full. Then one day, the little ones left the nest. I wasn’t there to see this exciting event, alas. I took this video the day before the nest was suddenly empty:
The little ones are now all round the garden, peeping constantly to get the adults’ attention. For the most part, they’re tucked away safely in the foliage, hard to find from my vantage point on the ground. This picture is of one of the little ones, a few days after leaving the nest:
Here’s the empty nest, with a clothes peg for scale:

Magpies carolling with a view of Sydney Harbour
This morning I walked along a path overlooking Sydney Harbour and the headlands that act as a gateway to the ocean. A treeful of Australian Magpies provided musical accompaniment.

More calls of the Grey Shrike-thrush including a sneeze
A few weeks ago, I posted my first video featuring the call of the Grey Shrike-thrush. I’d read that these birds make a variety of calls. Here are two more to add to the collection: A, short, high-pitched shriek and a longer call interrupted by what sounds like a sneeze or a snort!
When I first heard the sneeze-interrupted song, I thought the bird had made a mistake. But it made the same call consistently over quite a few minutes. Maybe the call is this bird’s variation on a theme, or perhaps the bird is a juvenile who’s still perfecting its song!

Call of the Grey Shrike-thrush
I’ve heard the lovely, clear calls of this bird a few times, always in the same spot on one of my favourite walks. Now at last I’ve identified the bird. It’s a Grey Shrike-thrush (I’m pretty sure) and this is only the second time I’ve managed to get some pictures of one of these birds.
In this short video, you can see glimpses of the bird and hear its call:
Evidently these birds have a variety of calls. In the next video, the same bird is singing a slightly different tune:
The next video gives a much better view of the thrush in its favourite gum tree, but the bird is taking a break from singing. In the background are the harsh calls of a wattle bird:
The bird is rounder and more fluffy than the drawings in my bird book, but the colouring and the song seem right for a Grey Shrike-thrush. I think the difference arises from the fact that there are different races of this bird in various areas of Australia.
The wing feathers have a lovely olive tinge, blending in nicely with the gum nuts and leaves:

Local cockatoos excited about new tree stumps
Over the last few weeks, our neighbours have been cutting down some tall trees on their property. The local cockatoos are excited about the new tree stumps that have appeared in their neighbourhood. (I call them “stumps”, but they’re several stories high.) The birds arrive on most evenings to sit on the stumps, and have started hollowing out the centre of one of them. I guess the cockies may be thinking the tree would make a good nest.
You can see the tree felling in my earlier post, Magpie scolds tree feller.
Call of the Red Wattlebird
This Red Wattlebird was quite chatty in the crisp morning air.
Usually when walking in the bush I hear the more raucous croaks of this bird and its cousin, the Little Wattlebird. So it was nice to hear something a little more melodious.
Here’s a still picture of the Red Wattlebird, showing the red flap below its eye which gives the bird its name:
The feathers on its back are quite decorative, and a sun ray lights up the yellow on the bird’s belly:

Eastern Whipbirds chatting and pecking at tree
An Eastern Whipbird was busily pecking at a tree, presumably to get at insects or grubs under the bark. Pretty soon, another bird joined the first one. They had an amiable chat. It looked as if they were consulting on how to tackle this troublesome hard bark on the tree. The first bird went back to the task while the other looked on. After a while, the first gave up and the second stepped in to give it a go.
I think the birds are quite young, because their feathers are a little untidy and the white cheek patches aren’t clearly defined. Perhaps they’re siblings!
It was interesting to see the birds interacting and to hear their chatting sounds. I often hear the long drawn-out call that gives these birds their name (this post has some examples) but I haven’t seen them chatting before.
