White Bellied Sea Eaglet 28 dominates feeding

The golden glow of the morning sun kissed the branches of the old Ironbark Tree in Sydney’s Olympic Forest. WBSE 27 and 28 were sound asleep in the nest bowl while an adult was on the parent branch keeping watch.

This morning breakfast arrived at 9:20:11. It was a nice chunk of fish.

28 was up at the breakfast table right away and dominated the feeding. There was no pecking and 28 was on the left side! Well, well.

It is easy to see that 28 really loves the fish! One of the things people have noticed is that the birds actually do have preferences. Some prefer fish, others prefer birds. Some don’t like specific species of birds. WBSE tend to really love their fish!

Here is a short video clip of the feeding.

WBSE 28 is still being fed after ten minutes. Indeed, Lady will still be feeding 28, almost exclusively, for another twenty minutes.

At 9:30:11 either a Pied Currawong or an Australian Magpie swooped down on the nest. Lady alerted and both of the sea eaglets pancaked on the nest.

Anyone watching the feeding would have immediately known that Lady’s alert call meant ‘danger’ and the sea eaglets stopped everything and became very still. This is what all raptors do, as far as I know. It is certainly what Osprey chicks do when their parent is alerting.

Oh, these eaglets love this fresh fish! 28 has gotten very good at the quick snatch method as well. He is very cute.

Lady finished feeding the pair at 10:01:27. They both settled down, each with a crop – 28’s was the biggest! He is in front sort of sitting up.

Right now it is easy to tell the difference – 27 has more juvenile feathers on its shoulders and wings.

No doubt, WBSE 27 might well dominate the next feeding. But it is significant to note that 28 stepped up first and was fed – and went to sleep with a very large crop. There was absolutely not a hint of sibling rivalry other than the typical ‘snatch and turn’ of 28 at times. The ‘snatch and turn’ is often a side effect reaction – grab the food quickly and turn – protecting one’s head from being pecked earlier in the chick’s life.

These two are doing very well. I hope that the Magpie or the Currawong – as well as BooBook Owl, and others do not inflict any injuries on any of the sea eagles. In fact, some of you might remember that it was a Magpie that helped WBSE 26 last year against the Pied Currawong.

The top two images are of a Pied Currawong and the bottom one is an Australian Magpie. Sometimes you only see a blur. Those familiar with the sounds of the forest might be able to tell who caused the ruckus.

There are decided differences between the two but a split second sweep of black and white makes it difficult. The Pied Currawong has been a constant in the Sydney Olympic Forest. Perhaps it has a nest near to the sea eagles and wants the big birds – the top of the food chain – to get out of town!

Sadly, the Currawong did chase 26 out of the forest and she wound up the next day, after a storm that evening, on the 22nd floor of a condo building about 1.5 kilometres away from the nest. The Currawong are a big problem in the forest. They also chased 25 out when it fledged and I suspect they have done this in years past. 25 never returned to the nest. No one knows what became of her. Ideally, these two beauties fledge and return to the nest for rest and food just like the Bald Eagles or the sea eagle fledglings are fed down by the Parramatta River by the parents til they can survive on their own.

It has to be mentioned that Sydney’s Parramatta River is full of dioxins. Commercial fishing is banned after elevated levels of the toxins were found in seafood from the Sydney Harbour and the Parramatta River.

The toxins leaked into the river from a shipping container company as reported in The Sydney Morning Herald on 16 May 2009. The article said, “The Patrick’s site on the Camellia peninsula, near Rosehill Racecourse, has been found to be leaking the chemical Chromium VI, posing a risk to people and marine life.”

In 2017, 2ser 107.3 reported that the Parramatta River was a “toxic time bomb.” They said, “Fifty years of toxic chemical residue is sitting on the bottom of Sydney Harbour and the Parramatta River. It’s a toxic time-bomb and disturbing this sediment could worsen already dire pollution levels. And now sweeping developments along the shore of the River could be bringing more pollution to the already sullied waters.” While many might have hoped to swim in the river before they were too elderly to do so, contaminated storm water was pumped into the river in December 2020 causing more problems.

That lovely fish that the two sea eaglets ate this morning came from this river. It is a tragedy.

Thank you so much for joining me. These are just the cutest little sea eagles. 28 is quite the character. Spend some time watching them. Everything is good.

Thank you to the Sydney Sea Eagle Cam @ Birdlife Australia’s Discovery Centre for their streaming cam where I took my screen shots and video clip.

The Hornbill

There are over 50 different varieties of Hornbill. The one that I want to focus on today is the Rhinoceros Hornbill. It is the State Bird of Malaysia. I became acquainted with these amazing birds during a trip to the Sarawak in East Malaysia many years ago.

The arrow points to Sarawak. The Rhinoceros Hornbill is present also in Sabah as well as Borneo, in yellow.

You could not move through the area around the harbour of Kuching without seeing ‘something’ decorated with the motif of a hornbill – from table cloths, batik wall hangings, phone cases, and old and not-so-old wood carvings. To actually see these highly endangered birds you needed a guide to take you to the jungle areas where local tribes still live in their long houses. There the hornbill was also used as a design for the totems on the poles supporting their roof as well as on many of the art of tattoos.

The weavers of the area specialize in ikat. Ikat is a type of resist dying. The threads are resist dyed before they are woven. The pattern in the textile below is called the ‘Feather of the Hornbill’.

Old carving of Hornbill, Ironwood. Sarawak Museum, Kuching.

The Rhinoceros Hornbill is depicted in numerous designs in wood carving. The wooden figure above is a Kenyalang. Historically, these carvings were associated with many of the tribes in Sarawak, Sabah, and Borneo. For the Iban, the figure is an essential part of a celebration called the Gawai Kenyalang. Its role was as a messenger. It called upon the spirit world to give courage to the warriors who went out headhunting. The carvings are still made today and they are still important for the various tribal communities. Head hunting ended in the 20th century and most of the carvings are considered cultural icons.

The Rhinoceros Hornbill is a large bird, 80 to 90 cm (31–35 in) long. The males are larger than the females. The birds are covered with black feathers except for the white tail that has a single black band. Their legs are white. The Hornbill is most notable for its colourful bill which is huge. In fact, that orange and red bill is what gave the bird its name. The Hornbill uses this lightweight beak to gather its food, build its nests, seal the nest, and feed the chicks. The structure on top of the bill is called a casque. It is hollow and its function is to amplify the call of the birds. The eyes of the male are red with black rims while those of the female are white with a red rim like the one below.

In comparison, this is an image of the male so that you can see the difference in their eye colour. It is the easiest way to recognize each of the genders.

The Hornbills are very unique in their nesting habits. They are cavity nesters but with a twist. When the female is ready to lay her 1-3 eggs, she will locate a cavity in a tree trunk (or sometimes a rock formation) to make her nest. Once made she helps her bonded-for-life mate seal her into the cavity with mud. The only opening is a small oval hole where the male feeds the female during her confinement that lasts 50 days. He also feeds the nestlings. This arrangement is very practical. It helps protect the nest from any type of predator including lizards and snakes. Ninety days after the chicks hatch, the female will break open the mud covering to the nest.

The Rhinoceros Hornbill is listed as vulnerable. One of the biggest threats to its existence is the loss of the rainforest where it lives and builds its nest. It is also hunted for food as well as for items that are believed to give men virility including the feathers and the skull. The large trees that occupied the forested areas of Borneo are being cut down at an alarming rate. When I was there the wood was being shipped to China on those huge boats. It was overwhelming to see the forest being obliterated.

In other news, Tiny Little Bob or Blue 463 nabbed the first fish of the morning on the Foulshaw Moss Osprey Nest in Cumbria. Tiny Little was busy eating it while sibling 462 waited on the nest. Tiny Little is off to a great start to the day! Go Tiny Little!

Karl II arrived at 8:10 to feed the three fledglings on the Black Stork nest in Estonia. The fledglings were incredible.

The glare of the sun on the camera creates a strong glow so you can’t see clearly what is going on. Karl arrives on the right and feeds the hungry storklings quickly. The nest is in the Karula National Park in Estonia.

One of the Storklings on the Siguldas Black Stork nest in Latvia has decided to get up close and personal with the camera and its supports while it waits for Grafs or Grafiene to bring them their breakfast.

The good news at the Peregrine Falcon Nest in the scrape box on the grounds of Charles Sturt University in Orange, Australia is that Izzi – cute little Izzi – has not been in the scrape box for six days. He has been heard but he has not gone in after several altercations with Xavier. Diamond, Izzi’s mother, is expected to lay her eggs by the end of August. Here is Diamond looking out over her territory.

Also in Australia, the two little sea eaglets, 27 and 28, are just cute. They are really growing. Dad brought in a life fish and was going to feed them today. Lady flew in and stepped on the fish before it could flop all over the chicks. Then she took over the feeding. Both ate well but 27 had an enormous crop.

It continues to be as good a day as it can be in Bird World. The juvenile Ospreys are eating and eating preparing to being their migration. For some of the UK nests the average number of days is around 90 hatch days old for fledging. We will be keeping our eyes open to see who is leaving.

Thank you so much for joining me. Have a wonderful Friday everyone. See you soon.

White-Bellied Sea Eagles and the birds that visit their nest

In a 2014 article in The Smithsonian Magazine, Rachel Neuwer asks why there is a Sulphur Crested Cockatoo in a Renaissance image of the Virgin and child, Madonna della Vittoria. Rebecca Mead examines the image by Andrea Mantegna, painted in 1496. You can see the painting of the Madonna and child with saints in the article below (sorry, it has a copyright so I can’t show it). The Sulphur Crested Cockatoo is above the Virgin’s part in her hair a little to the left.

As I drank my morning coffee several days ago, I flipped through the latest New Yorker. In that 5 July edition, there is an article, Invasive Species.

https://www.newyorker.com/magazine/2021/07/05/where-did-that-cockatoo-come-from

Each writer considers how the Sulphur-Crested Cockatoo made its way from AustralAsia all the way to Italy focusing on the initial discovery of the bird in the painting by Heather Dalton, a British historian living in Australia.

The Mantegna is not, however, the first time that a parrot is included in a picture. Parrots show up in the murals of Pompeii, the Italian city buried by ash when Mt Vesuvius erupted in 79 CE. They are also the subject of floor mosaics in the region. Indeed, exotic birds (not just parrots) appear as subjects in many mosaics and frescoes in the Roman domus.

Alexander the Great’s army went as far as parts of India before stopping on their eastern expansion of his empire. Their presence on what is today the Indian subcontinent heavily influenced the art of the Gandharan region. In turn, Alexander acquired a parrot from the Punjab in 327 BCE. If parrots were in Italy 1700 years before the Mantegna, one might begin to ask what is all the fuss? The Barber Institute of Fine Art in Birmingham, England hosted an exhibition solely on parrots in art in 2007. They were exotic, they were status symbols, and it appears that they were present in the art of the Italian Peninsula for some 2400 years to today. Of course, they were not all Sulphur-headed Cockatoos and that could well be the reason for the continuing discussion about the Mantegna. Other species of parrots came from the southeastern coast of Africa and from the region of the Indian subcontinent and Southeast Asia. Sulphur-Crested Cockatoos originate in Australia and the islands of Indonesia and it was surely the trade through the islands of Indonesia that spirited the bird all the way to the port of Venice along with black peppercorns and other spices.

Sulphur-Crested Cockatoos are extraordinarily beautiful and are the largest of the white parrots. I have never seen them in the wild. Indeed, it was not until I watched the White-Bellied Sea Eagle streaming cam in the Sydney Olympic Park that I heard them before I saw them. It sounded like someone being murdered in the forest! Seriously. One of the moderators answered the question, “What is that?” Later, these lovelies were seen climbing all over the old Ironbark Tree.

Sulphur-crested cockatoos are nut, root, and fruit eaters and live for up to eighty years. They make their nests in tree hollows where the female lays one to three eggs. Those eggs are incubated for thirty days. The little ones remain in the nest being fed by the parents for a period of approximately sixty-five days after hatch. The breeding season for these parrots is August to January in the Southern Hemisphere.

Why am I talking about these parrots today? It is because of the White-Bellied Sea Eagles (WBSE), Lady and Dad. The two eggs that Lady has been incubating will be hatching in approximately two weeks. There is a live streaming cam that is on day and night, 24/7 year round except for maintenance. If you like birds of Australia, you can often see them coming and going around the Sea Eagles nest. The birds are either curious as to what is going on in the nest or they would like the Sea Eagles to leave! The streaming cam in the Sydney Olympic Park is the only one in the world that observes the second largest eagles in Australia.

It is in the middle of the night. This is the WBSE nest in the Ironbark Tree in the forest of the Sydney Olympic Park.

The Rainbow Lorikeets are curious. They come as a group climbing all over the branches of the tree. They are easy to spot!

Every once in awhile the Galahs come to the Ironbark Tree. I think they are adorable. One of the WBSE chatters from Australia said that if anyone visits Australia and someone calls them a ‘Galah’, it is an insult meaning the person is not very smart. I have no idea how the Galah got that reputation except that I have seen several in the talons of Peregrine falcons in Australia.

The Noisy Miners are definitely heard before they are seen. They are a constant in the forest around the WBSE Nest.

The Pied Currawong flits around the WBSE nest all the time. I do not like them! Once the nestlings have fledged the Currawongs gather and try to chase them out of the forest. They did this on the first try with WBSE 25 last year and during the re-fledging of WBSE 26.

Then there is the smallest owl in Australia, the BooBook. Isn’t it cute? This owl, like all others, flies silently and it can see very well in the dark. It comes in the night hitting the WBSE has they roost for the night. They fly low over the nestlings trying to hit them and make them leave. One attack injured Lady’s eye last year. Despite their size they are to be taken very seriously. The BooBook often has a nest in the forest the same time as the WBSE so it is very protective and wants the eagles gone for fear they will eat its young.

Here is a compilation video of Lady and Dad after the first egg was laid through the 23rd of June. It shows the actual labour of the second egg and a changing of the incubation shift from Lady to Dad.

Here is the link to watch the WBSE in the Sydney Olympic Park:

Be sure to check out the time difference. One of the most beautiful moments of the day is when the adults do a duet at sunrise. It is an amazing way to start the day. It wakes up the forest but it is also a continuous bonding method between the birds. The nestlings will join in with their parents when they are older. It will warm your heart. Here3 is a video clip I made after Lady laid the first egg. She leaves the nest and joins Dad on the branch for the singing.

Thank you for joining me today. It is now three days since Tiny Tot was at the nest. We are all having Tiny withdrawal. Take care everyone.
