Will the Melbourne Four fledge? …and other news in Bird World

7 November 2022

Good Morning Everyone!

I am so sorry that the link I published to the story of WBSE26 did not work. The one under question 1 below works! Thank you ‘J’ and ‘H’ for alerting me to this issue!

___________________________________________________________________

It is actually 2030 on the Canadian Prairies, Sunday evening, and the snow that was forecast, arrived. The precipitation goes back and forth between snow and freezing rain so it is like a slushy drink outside. The garden birds will not be happy. Watching them during the torrential rains last spring, it is readily apparent that they prefer the snow (dry snow not heavy wet) to the rain. Their food does not ruin and they can fly easier. So many prefer to eat directly off the deck than from the feeders that I worry about them when it is so wet. Will this snow be here in the morning?

It stayed. The squirrels have run all over the place. Dyson was here early with her two kits.

The miniature weeping Caragana and Japanese lantern look lonely this time of year.

One of Dyson’s kits. The other is in the lilac bushes.

On the Bookshelf:

One of my biggest complaints about bird guides is the images. We have a locally published book on Manitoba Birds. It has drawings instead of photographs and they are lovely but, they are only helpful to an extent. Sometimes there is only the image of the adult male. There are never immatures! And definitely not an immature female bird. How are we supposed to learn which is which in the garden? Merlin ID has driven me crazy. My best book for sparrow ID has been the hefty Crosley’s Sparrows. But, what if you want to identify other species? Some have pictures or drawings the size of postage stamps and the layout designer used the size 8 font so that anyone over the age of 30 or someone with poor eyesight cannot read the text.

There is a new book out that will help those living in Europe. You might still need a magnifier to read the text or probe the maps, though. The book is Europe’s Birds. An Identification Guide. It is a weighty volume. You will not be hauling it around with you in the field but, it should be a much used reference for home. The images are far superior to any I have seen in other volumes. In Canada, the hard copy is $36…well below the average of some of the other guides that take up space but do not help one bit with IDing a bird!

In the Mailbox:

Oh, I love getting questions! There were 3 today and all of you might be wondering about one or more of them.

1. ‘J’ wrote about having difficulty opening the link to the former blog about WBSE26. I am so very sorry if this happened to all of you. Here is a link that works. 26 is inspirational and needs to be remembered for all the joy and encouragement she gave to all of us in her short life.

January 5 is National Bird Day!

2. ‘K’ wrote: ‘Will the parents continue to feed the chicks on the ledge in Melbourne after they fledge?’

‘K’, that is a difficult question to answer. Normally, the adults would begin teaching the eyases how to hunt when they fledge. They would deliver prey to them in mid-air transfers and would be finding other places to feed their fledglings. The previous couple did not feed the fledgling falcons on the ledge. Mirvac turned the camera off at that time. These are first time parents and we will have to wait and see but I assume the answer is ‘no’, they will not bring prey to the ledge for the falcons if they have fledged. Prey would be taken to those that have yet to fly. You might also have noticed that the adults have begun to reduce the amount of prey that is being delivered. Food is a great motivator!

3. Several asked, ‘Will the Collins Street eyases fledge one by one or will they fledge together?

Like question 2, this is difficult to answer for several reasons. Males tend to fledge before females. The reason is simple. It takes females longer to produce all the feathers for their larger size than the males. At the present time, we do not know the gender of these chicks and it is likely we never will as they are not ringed nor has any blood been taken to determine gender. We should, however, expect the male to fly first. Victor Hurley has said he believes that there are 3 females and 1 male. But is the male the 4th hatch or the 1st? or the 3rd? Hatch order and gender could impact the timing of fledge. So if the male is the 4th hatch he might fly the same time as the 1st if that bird is a female because of the difference in their ages.

I have seen many nests where the eyases get so excited seeing one of their clutch fly that they all fly off within an hour. It has happened at this ledge. Now that the youngest has made it to the window ledge, I am wondering if the eyases might not all fledge within an hour or one another. We should know the answer to this question soon! I know that this does not answer your question. It might even confuse it more and my apologies. We just don’t know! They will keep us guessing until they take off…and then we will wish them safe skies, long lives, and full crops.

Fledglings depend on the parents from 4-6 weeks to help and teach them how to hunt and obtain prey. They will then leave the parent’s territory.

One of the most difficult things about getting close to the birds is not knowing what happens to them. Some people prefer to not know while others like myself, want to know every detail of their life. I think that is why satellite tracking is so interesting to me or a book such as Bowland Beth.

Australian Nests:

You might well have noticed. Mum and Dad at the Port Lincoln Osprey barge don’t seem to be in such a big hurry in the morning to get up and off and find fish. Dad appeared to have a leisurely morning and Mum went and had a spa break. Good for her. She must eat and take care of herself.

Mum and Dad are also spending a lot of time with one another. Mum has fed Dad – a tender thank you for the food he brought when she was so desperately hungry -, they have sat together in the shed, and now they are spending time on the perch. If someone believes that they are not mourning, they need to consider the behaviour of these two beautiful ospreys who have lost two chicks. The loss of Middle had to be particularly difficult, a fully feathered osplet.

Dad flew in with a large whole fish. It looked like Big wanted that fish for itself but Mum prevailed and kept control. She remains in charge of the feeding. Is this on purpose? Big is now the age that she should be self-feeding. Big hatched on the 18th of September. If we count hatch date, Big is 51 days old. She will be ringed anytime between today and Thursday. We should be able then to confirm the gender, the weight, a name, and see Big with her tracker.

I had to laugh. One of the chatters said that, ‘Big is just an eating machine’. That is possibly why Mum still controls the reigns of the fish so that she gets fed properly, too, when an extra nice fish like the one that came in this morning is delivered.

Look at that fish. Wow!

Watchers of 367 Collins Street are having a hard time deciding if any of the eyases have fledged. They are such beautiful eyases. At 1400 all four were on the ledge.

‘H’ did a great compilation of the 4th hatch, ‘little Peanut’ branching up to the window ledge. Watch as the others come down and do a ‘cheer’ for the wee one.

Indigo and Rubus are changing every day. Like Big, Rubus is a bit of an ‘eating machine’. When Rubus hatched and was so absolutely tiny and couldn’t get up to eat – do you remember? -, I felt so sorry for Rubus. Indigo was just tall, stoic, and elegant. At one point it seemed like Diamond didn’t want to bend down to feed Rubus. And then…Rubus started jumping and stretching that neck. What a long neck and well, that is all history. Rubus practically knocks the parent over if there is food. Indigo appears to want to look out to the world beyond and feed herself. Rubus gets fed but is doing quite well at self-feeding, too.

‘Hello Everyone!’

Rubus was very happy that Indigo left some prey.

Rubus is doing a great mantling of the second prey delivery. Indigo is not interested. She ate most of the earlier delivery and is looking out to the world where she will be flying with her parents – the fastest bird on the planet!

Look at Rubus’s wing feathers. Lovely. We will wake up one morning and Rubus will look like Indigo. What a shock that will be!

At 1642 prey was delivered. Indigo expected to get it but, Rubus was quicker grabbing the item and carrying off into the corner by the Cilla Stones.

Indigo is telling Xavier and Diamond about how naughty Rubus was taking her prey!

The adults leave the kids to it…Rubus takes the prey to eat it in the back of the scrape while Indigo comes over and wants the food. Rubus turns quickly to protect his meal and heads back to the Cilla stones. Rubus has had some good fast bites.

Indigo will eventually get the prey from Rubus through the great ‘stare down’.

What’s Up with the Eagles?

Harriet and M15 have been working really hard rebuilding their nest that was completely destroyed by Hurricane Ian. Lady Hawk has posted a video of their progress. And guess what? Harriet is sleeping on the nest tonight. Eggs might be coming soon!

Philippe Josse posted some super screen captures of Mum and Dad at the Notre Dame Eagles nest in St Patrick’s Park in South Bend, Indiana. This is the home of our beloved Little Bit ND17 – the little eaglet that could. Their nest completely collapsed and many wondered if they would rebuild in the same place. They did and both have been walking around testing the nest to make certain it is sturdy. Thank you, Philippe!

Jackie and Shadow continue to work on their nest in the light snow in Big Bear.

And last but, never least, some great news. I have been tracking down information on ospreys that went into care before they fledged. There is an urban myth that they do not do well in care and, in particular, before fledging. You might remember the two osplets that had not fledged at Pitkin County Open Spaces and Trails. Their mum pulled them off the nest by accident. One died while the other went into care. It is doing great and is being over wintered and will be released in the spring. Urban myth proved wrong. (I have been asked not to publish the name of the wildlife centre as they do not have the staff to answer queries). This is good news and details will be sent to Port Lincoln.

Banding will take place anytime between today and Thursday at Port Lincoln. I have seen no specific time or day indicated yet.

Thank you so much for being with me this morning. Please take care. See you soon!
