Catching up with Miss Daisy

You will remember from my earlier posting today that our favourite little duck, Daisy, got home to her nest at 19:03. A couple of hours later and not having any evening contact with the mated pair of White Bellied Sea Eagles, Daisy was relaxing. And then BooBook Owl came and scared the wits out of her. She did not leave her nest but she got in defensive posture ready to protect her nest. At first Boo flew low right over Daisy on the nest. It is 20:51:40.

In the image below, Boo is nothing more than a blur as she flies directly over the centre of the big sea eagle nest. She is so close that she almost touches Daisy when she does the fly through.

The blur of BooBook Owl.

Daisy immediately gets into defensive posture. Boo circles the nest flying around the branches, going round and round. It keeps Daisy attentive and moving with the small owl. She always wants to know where the owl is. At 21:06:35 Boo lands on one of the small branches up near the top right corner of the image below. You can see the legs on the branch but not clearly. Look carefully. The left leg appears lighter than the right.

Defensive posture.
Boo moves closer down the branch to have a good look at Daisy.

BooBook Owl finally decides to sit closer to Daisy. Now you can see the eyes, the beak and the left leg along with the little owl’s body.

Boo is a nuisance to our Daisy, right now. She is also curious about this little duck in the sea eagle nest. Boo is used to bumping into the eagles in the night often injuring Lady’s eye. Boo is especially aggressive when she has her own nest of babies, November-December, and would love it if she could harass the sea eagles enough to get them to leave the forest. Fat chance on that happening!

Boobook is the smallest owl in Australia. Owls are nocturnal so that is why Boo only pesters Daisy after dark. Boo will hunt all kinds of insects and very small mammals such as mice, small bats, and moths. Boo is about 27-36 cm tall or 10-14.5 inches, and weighs only 140-360 grams or 5 ounces to 12.6 ounces. The wings span ranges from 188-261 mm, or 7-10 inches. In comparison, remember that the White-Bellied sea eagle is the largest bird in Australia with a wing span of 2-2.3 metres, standing 80-90 cm tall and weighing 2.5 to 4 kg. Pacific Black Ducks are approximately 54-61 cm or 21 to 24 inches in length and they weigh 1025-1114 grams or 2.25 to 2.4 pounds. Daisy is bigger than Boo but the most important thing for her right now are her precious eggs and their protection. Boo could make a terrible mess and while the little owl does eat insects and bats along with mice, it might also be interested in Daisy’s eggs.

The sea eagles did not show up this morning. They were at Goat Island and it was raining and windy. Daisy’s morning was, as posted earlier, rather uneventful til she starting listening and raising her neck listening to the vocalizations from the other birds in the forest.

At 9:29 the ravens arrive. You cannot see them but Daisy heard them coming and knows they are about on the nest tree. The little duck immediately goes into a defensive posture. Notice, in the image below, how she has fanned out her tail and she has her feathers puffed up. This makes her look larger.

The Unkindness stay for approximately twenty minutes. Daisy moved as they did, just like she did when Boo was on the nest tree. She always kept her head tucked, her tail fanned, and her other feathers puffed.

As the day wore on, there were periodic showers on the nest. Daisy did some housekeeping, moving leaves closer to the nest in case she needed them for cover.

By noon, Daisy was relaxed and ready to take a wee bit of a rest. She tucks her bill in under her wing for warmth. Instead of being 40 degrees C like it was two days ago, today it is only in the low 20s with showers. What a change in temperature!

Daisy begins sweeping the leaves toward the nest and tucking the now dry down inside. She is preparing to go foraging. It is 13:58:14. This is quite a bit earlier than the last several days.

Daisy has camouflaged her nest well. In with the fluffy down are some leaves and twigs.

Leaves and twigs help hide the nest.

It is now 16:04 and Daisy has not returned to the nest. She often returns around 19:00 or 20:00 right before dusk but when she has left this early she has come back around 16:45. One day Dad had arrived and she had to abort her landing on the nest to avoid him seeing her. I wonder when she will come home today?

Thank you so much for joining Daisy and her adventures in the big sea eagles nest!

Daisy ducks!

No sooner than I had posted my last update on Daisy, than the little duck got busy covering her eggs and going to forage. The time was 14:41:26. It is in the normal range of when she leaves the nest. Sometimes she has not returned until dusk because she knows she will avoid the sea eagles. Now that she is getting nearer to hatch, will she stay away that long?

Covering the nest

As she leaves she finds some down that she has missed when restoring her nest. She loosens it from the twigs and pulls it down to the floor of the nest.

This time Daisy has tucked the down and added some leaves at the side. She tried to fold the top onto itself but not getting it tight like she did during the early stages of her incubation. Let us hope that the gusts of wind do not pull the down apart leaving the eggs open to eating or destruction by the Ravens or the Currawongs.

You can compare the next image below to the one right above. Look at the fluffy light down. Looks like it has twinkly stars embedded in it.

Well the rain became heavier and made its way through the canopy of leaves.

There isn’t much difference in the image above and the one below except for the down covering Daisy’s nest. It has begun to rain just a little harder with more of the drops making their way through to the nest. Daisy’s nest looks so wet and so sad without her in it. It is 17:50. Wonder how much longer she will stay away? It is 20.3 degrees and rain is forecast through Sunday.

The protective down gets very wet.

Daisy returned to her nest at 19:03, an hour before sunset. She was a very wet duck! The nest was soaked and the down was a solid wet glob.

Daisy is a little soaked.

Daisy settled in at the task in hand. Daisy was away from the nest for five hours. The sea eagles did not return at dusk. Whew! But, two hours later, once it is dark, BooBook Owl comes to call and scares Daisy by flying from branch to branch.

Ducking!

Daisy flattens herself over her eggs increasing the size of her body and extends her neck. She is in protective mode. Boo bothers her for about a minute and a half and Daisy goes back to incubating her eggs.

The old Ironbark Tree where Daisy’s nest is located.

It is now 7:34 in the Sydney Olympic Park. The heat from Daisy’s body and the wind have dried out the down. The sea eagles did not arrive. They have been spotted at Goat Island. That does not mean that they will not return. It just meant that Daisy didn’t have to scurry from the nest before dawn. A good way to start the day, nice and relaxed.

Daisy and the down have dried. Rain is forecast for today.

It may look boring but a boring, quiet day without any visitors to Daisy is a good day! Let us all hope that it stays that way for her.

Yesterday, some of you noticed that Lady didn’t like the down. It looked like is was sticky. Now we know that sea eagles do eat birds so, Lady would be very familiar with feathers. But she might not know about eiderdown. This is what I was told from someone very familiar with ducks and geese, “Cling is an attribute of eiderdown and very mature goose down, also known as”sticky down”. “Cling” is found when tiny hooks develop on the individual filaments of a down cluster”. I immediately thought of Cling film that we pull over bowls and things to keep food fresh. It sticks to itself and to the bowl. Well, that is precisely what Daisy’s down did to Lady. It must cause Lady a lot of confusion. And, you know what? That is OK. I know that this is Lady’s nest where she raises her eaglets. But Daisy is not a threat to the sea eagles or their babies. Yes, she chose their nest but this might have been because she lost all of the ducklings in her first brood this season and she wanted to see if this nest might help see some of them to hatch. I know that each and every one of you are cheering our little duck forward.

One of Daisy’s fans also sent a video for all of you to watch. A Mandarin duck made her nest on the balcony of an apartment twenty-stories up from the ground. It is an amazing video showing how the people of this city came together to help the ducklings. Have a look!

Daisy wants to thank all of her friends wishing her success. People have joined her from Canada, the United States, Australia, Mexico, Poland, Croatia, China, the United Kingdom, and Brazil. Check back for updates. We are getting closer and closer to hatch!

Gusts and a creaking Ironbark Tree kept the curious away

Daisy might have been awake all night with the loud creaks and swaying of the Ironbark Tree in the frequent gusts of high winds last night but not a single intruder was spotted. BooBook Owl stayed home. WBSE Dad didn’t venture out to check on the nest in the evening or this morning. It has been more than twenty-four hours since he has been about. Spotters on the ground say that he is off at Goat Island, some 12.2 km away, with Lady. And, so far, Raven has not made an appearance. It is nearly 7am, the tree is creaking gently and Daisy is quietly doing nest maintenance. If you squint your eye, the white in the down lining of the nest looks like little twinkle lights.

Notice how Daisy turns clockwise in the nest as she continues maintenance and rolling the eggs.
Daisy continues to take down from her breast adding it to the nest and turning clockwise.

Sometimes Daisy will quickly get off the eggs to go and fetch more plant material somewhere else on the big WBSE nest that she can’t reach by extending her neck as far as it can.

Daisy quickly leaves nest to gather up more plant material from the WBSE nest.

When Daisy prepares to leave to forage for food, which she did last evening for about an hour, she tucks the down into the nest cup folding it over on the inside. She also uses her beak and stretching her neck she pulls leaves up close. This way she can cover the eggs while she is away. Of course, we have now seen times when Daisy is frightened off the nest by both the WBSE Dad and BooBook Owl but, normally, she takes the time to gently and quickly conceal those precious eggs.

Daisy continues to use her bill to bring in leaves and plant material close to the neck cup. She might be preparing to cover the eggs and leave for a quick morning foraging.

I wonder if you have ever thought about the amount of energy it takes a duck to lay an egg? I certainly hadn’t until this year when I watched Bald Eagles have hard labours when laying an egg and then Daisy. Those eggs don’t just pop out easy!

Sibley says that a single egg can weigh as much as 12% of the bird’s body weight. For Daisy, remember that she layed an egg every day for nine days. That has to be exhausting! Specials with precocial young often lay more eggs because the mother does not have to feed them. Precocial young are more fully developed when they hatch. Their eyes are open and they are fully feathered. In the case of the Black Pacific Ducks they can walk and find their own food. Remember that the ducklings will jump off the nest and follow the parent to the water to forage for food. They will actually jump off the nest before they are fully capable of flying like their mother. Daisy will keep them warm at night for approximately two to three weeks. Altricial young require much more care. They are born without feathers and require their parents to feed them until they are capable of self-feeding. A good example of an Altricial young is a Tree Swallow.

It is now after 10 am and Daisy has had only one intruder. The Raven showed up about 8am. Daisy quickly reached over and clacked, like she did yesterday, and off it went! Hopefully Daisy will have a non-eventful day on the nest. Fingers crossed!

Oh, what a ‘BOO’ tiful night or…not. BooBook Owl comes to check on Daisy’s nest and then Daisy is ‘RAVEN’

The feature image shows an Australian BooBook Owl sitting on the rim of the sea eagle nest where Daisy has her eggs. She flew off the nest as soon as Boo arrived.

Boobook Owls are the smallest owls in Australia measuring from 10.5 to 14 cm (27 to 36 inches) in length. Those of us watching the White-Bellied Sea Eagle (WBSE) nest in the old Ironbark Tree in the Sydney Olympic Park are very familiar with ‘Boo’. The BooBook eats insects and small vertebrates. They breed in late winter and early summer and have their nests in tree hollows. Little Boo is infamous for striking the adult WBSE when they perch on their nest at night and for flying at and hitting the juveniles in the nest. Once or twice this past nesting season, Boo inflicted injury on the eye of WBSE mom, Lady. Boo is a nuisance but not thought a tremendous threat to Daisy. The problem is when she is frightened and flies off of the nest leaving her eggs exposed. For all purposes, it appears that Daisy is like a single mom having to do the incubating and the defence. She is one tough little duck.

Daisy returns to her nest around 4:43 am, some three hours after Boo lands on the nest. She waddled slowly over to the nest, looking this way and that, making sure that there were no more intruders. She settled and began incubation as she could not feel any threats still around.

Daisy remained on the nest incubating her eggs until WBSE Dad comes to check on the nest at 5:39:25. This has to be one confused adult male sea eagle! There are eggs in HIS nest and he is trained not to step on eggs in case they might be his!

Daisy meanwhile made her quick escape just 25 seconds prior to the sea eagle landing.

Daisy could have been watching from a short distance because she returned to the nest as soon as Dad flew away at 6:30:29. This is one lucky duck!

After all the excitement of Boo and Dad, Daisy settles in to hopefully a quiet morning on the nest.

Two visits. It is a wonder that Daisy settled back on her eggs at all. Everything is quiet until 8:44. A raven lands on a branch of the nest and then jumps down to the rim! An egg eating raven!

An Australian Raven arrives on the nest rim.

The Australian Raven grows to 46–53 centimetres long or 18-21 inches. They appear an iridescent purplish blue-green and black in their plumage. They are part of the passerine family that includes crows. And they love eggs! Indeed, they are a great robber of nests. They are opportunistic feeders living on both plant and animals as well as food waste.

Daisy’s first reaction to the raven was to press her body flat in the nest. She appeared very frightened at first. And then she stood her ground. She leaned forward off of the eggs slightly and clacked at the raven. And, guess what? It flew away!

In the image below you can see Daisy stretching her neck and laying flat on the nest, just off the eggs, clacking. The tail of the raven can be see just slightly above the bottom right hand corner as the bird departs!

Daisy clacking at the raven to protect her eggs

Daisy has settled back on her eggs in hopes of a much more quiet day. Stay tuned! It is not even noon in Australia and no telling what is going to happen next in The Chronicles of Daisy the Duck.

Daisy often turns clockwise in her nest enlarging it and also you will see her go in with her head. She is aerating the nest.
Daisy continues to add down from her breast working to make it softer and softer.
