Step-Dad at Melbourne is Remarkable

10 October 2022

What we have been witnessing at the 367 Collins Street scrape in Melbourne this breeding season is providing ‘the gold’ of raptor research.

It has always been presumed that M (2017) was the father of the potential chicks in the eggs that were laid by F (2022) at the scrape box on the ledge. A territorial dispute happened between M (2017) and M (2022) with M (2022) usurping M (2017). He has not been seen since September. The former female was found injured in June and had to be euthanized.

Since the M (2017) was last seen, we have watched the new male ‘watch’ the female feeding the chicks. We have seen him brood them. We have seen him feed them.

For the past two days, the F (2022) has disappeared for nearly an hour yesterday at noon at the height of the heat leaving her eyases uncovered. Today, she has been gone since 11:01:48.

The chicks were clearly hungry and hot. Male (2022) or, better, Dad (not even Step-Dad) flew off the nest leaving the eyases alone at 12:45:12. He returned with a pigeon at 13:12:43 and is now feeding the four.

Can you see the tears rolling down my cheeks? Can he possibly keep this up? I really want to see him try. He can leave them and get a pigeon back to the ledge in half an hour. Is it possible that he can raise them by himself if the female never returns? I want to add that it is highly unusual for a female to be gone during brooding but I have seen it happen with Bald Eagles and Ospreys. You might recall that Gabby at the NE Florida Bald Eagle nest was gone for over a day and Samson took care of Rocket and Jasper. Blue NC0 needed a break and was gone from the Loch of the Lowes Osprey nest in Scotland for a similar amount of time. We will have to wait to see if the female at 367 Collins Street returns. We have no idea what has transpired. We only know that she has now been gone nearly 3 hours.

Clearly anything that can happen has happened at this nest.

We often say we understand the challenges that the raptors face but the situation at Melbourne is clearly bringing this home. A male Peregrine Falcon is feeding and will try to raise the chicks of another male – without help from their mother who is possibly severely injured or dead – that he probably killed or badly injured. I am immensely impressed. I hope that he figures out a way to be both mother and dad. I think he can if he hunts early in the morning. Gets a pigeon or two in a safe place and stays with the chicks during the heat of the day and keeps them shaded.

As Step-Dad departs, we can only hope that Mum will show up but, if she doesn’t, let us send this young male falcon who has no DNA ties to any of the four eyases on this scrape all our love and positive energy. He recognized that the chicks were hungry and needed food, he saw they needed shade and he turned himself into an umbrella — now can he raise them all alone if that is what is required? He clearly has a bond with them. I hope it is strong. His instincts are to care for them and that is a good thing.

Thank you for being with me. I have not stopped to check on the other nests because of the events here at the Collins scrape. I hope to have a good report for you tomorrow. In the meantime, take care. Stay safe.

SE29 fledges and the Dust Ups continue at Port Lincoln

2 October 2022

It has been a really exciting day (and it is only mid-afternoon in Australia) with the first fledge at the Sydney Sea Eagles nest in the Sydney Olympic Park. One of the parents was on a branch of the natal nest when SE29 flew. Another parent was with SE30 later. And then SE29 returned to the nest tree. I am still trembling with excitement. While we don’t know where SE29 flew to – perhaps just the camera tree – what we do know is that the Pied Currawong did not chase this amazing eaglet out of the forest to the Salt Marshes. So happy.

I will not have an early blog tomorrow. I am going to post this right away. Look for news from all the nests later on Monday.

In my last blog, Big and Middle continued their battle for dominance of the Port Lincoln nest. The two are pretty much evenly balanced and each gives as good as it gets. Both cause the trouble. Sadly, wee Little Bob often gets caught up in the misery.

Interestingly, they are quite civil at meal times! There was a nice big feed around 10:20ish. Little Bob had no problem stepping right up by Middle Bob and opening its mouth for fish!

Then Big and Middle started scraping again.

Then a big fish arrived and everyone lined up nice to eat. Perhaps Mum should just sit on them between feedings until the pair of them calm down.

After Big and Middle had their feed, Mum gave Little Bob a private feeding. Give her a round of applause. Mum is working hard to make sure that each of her children is fed. Little Bob sure can consume fish but, he needs a fewer more feedings in between. He is entering the big growth spurt now. So far he has demonstrated no real fear of the two big siblings. He even took a fish flake from Big Bob’s beak earlier.

There is enough fish for everyone.

At the Sydney Sea Eagles nest, the time for fledging draws nearer and nearer. On Monday morning (Australia time), SE29 flew to one of the lower branches of the nest tree. S/he waited there for a bit and then…did not fly off but rather, returned to SE30 in the nest. Bravo!

At 13:44:30 SE29 fledged. S/he had watched one of the parents on the branch and was looking over the edge of the nest and just flew. It was beautiful. Congratulations to everyone at Birdlife Australia and all connected with the Sydney Sea Eagles.

A parent waits with SE30. The siblings were so close to one another and what a fantastic year it has been with them and Lady and Dad. I wonder if SE30 will leave today or if SE29 will return later? We wait to see.

At 14:46:58 SE29 returned to the nest to join SE30 and the parent. Tears are just rolling down my cheeks. This is incredible. Normally the Curras chase them out of the park – it didn’t happen today.

Tears of joy.

Thank you for being with me for this great event. SE29 flew!!!!!!!!!! And SE29 returns safely to the nest.

See you soon — and take care of yourselves.
