Diamond lays second egg…Thursday in Bird World

29 August 2024

Hello Everyone!

Update: Diamond laid her second egg at 23:57 on the 29th. Thanks, ‘H’ for the news!

Oh, it started off much cooler Wednesday, but by 1500 was 25 C. Hugo Yugo was busy looking out the window at all the birds while all the others were having siestas.

This is Hugo Yugo’s favourite pose. She is often caught watching the telly leaning over the arm of the sofa.

She can be an angel.

The look of Calico when she is enjoying a good scratch!

Baby Hope (aka Calico Kitty Kitty) is just about as big as her mother. She is going to be 14 months old on 2 September.

My day is very hectic and it is possible that this could be the shortest posting ever! Things remain quiet with nothing untoward happening at any of the nests other than fledglings frantically fighting for fish and getting their talons caught or eagles returning to nests that require improvements. We have the second egg at Collins Street. These two are both apparently new falcon parents to this ledge. It goes to show you just how difficult life is within the world of tall buildings compared to Diamond and Xavier. The history of that couple at Orange is as follows and comes from the information below the streaming cam: “Diamond took over from the older Swift in 2015 and Xavier replaced Bula in 2016 (who in turn replaced our first male, Beau, in 2015). Xavier arrived just as the eggs were hatching and saved the season by providing for Diamond and her three chicks. Assuming that they were at least two years old when they arrived, Diamond is at least eleven years old and Xavier nine (in 2024).”

Most cite the average age of a peregrine falcon being between 12-15 years with the average maximum life span being 16-20 years. Research has shown that older female falcons lay fewer eggs and they are less fertile. According to Birds of North America‘s peregrine falcon article: “Female age has a significant effect on all measures of reproductive success: clutch size, fertility, hatchability, brood size, nestling survivability, and number of fledglings. In all but nestling survival, the data best fit a quadradic model, reflecting an initial increase in performance followed by decrease with age.”

The Raptor Resource Project has a good article on life expectancy of falcons:

Charles Sturt University and Dr Cilla Kinross have a page of questions and answers and they include this information: “Sadly, the mortality rate for juveniles in their first year is as high as 60% with accidents while learning flying skills a major contributor. Survival improves with each year of life thereafter, with a general six-year life expectancy for peregrines in the wild. There are exceptions of course, with Diamond and Xavier being prime examples, and wild falcons can live up to 19 years. Fertility in a female peregrine will decline with age. In effect, fewer eggs will be laid with some being infertile and others not hatching resulting in fewer fledglings.”

So we wait to see. Diamond might be considered a senior citizen in the falcon world. Will this couple have more eggs? will any of them hatch? We will have to wait and see.

Geemeff has taken a break to see ospreys and she says that the ospreys are catching fish and the white-tail eagles are coming out of the sky to steal then and then they are getting mobbed. Everyone wants free food. Don’t think for a second that life is easy for our feathered friends. it is anything but.

The Crows are clamouring for the cheesy dogs while the squirrels, Little Red and Dyson, work hard for their peanuts. It is a grey overcast day. The temperature was cool this morning, and they might feel, as I do, that fall is in the air. There is a notable change, just in a couple of days, with the colours of the leaves in the trees. A chartreuse, an ochre, and a russet weren’t there at the weekend.

Bywyd Gwylld Glaslyn released a video showing Aran delivering a whopper of a fish to the nest. Two fledglings, 6M8 and 6M9, there anxious. One grabs the fish and the other gets towed away by Dad! The comment was on how strong Aran was to lift that chick and carry it. No osprey was injured. I wanted you to see where the nest on the top of the tree is and imagine that the camera is refreshed annually along with the cot rails, if needed.

It looks to me like it was Antali and Iris on the Hellgate Canyon nest and then a rare appearance from Sum-eh (I could be wrong). If so, all four family members are still in the area and have not begun migration.

Feel free to correct me – looks like Sum-eh’s head markings.

Yes, Sum-eh was at the nest and her and Antali had a big fight for a fish! https://youtu.be/3iUo5CqrxwQ?si=PVTVat6Kp_EBp0Gq

Sum-eh won that round but Antali got a delivery of a live fish later! https://youtu.be/QuRL-7eaeOM?si=UmDZcq6tSEqtd7pb

At Port Lincoln, Mum is right on time and has laid egg #2 early Thursday morning. She holds her position and doesn’t give anything away letting the egg cool and harden before beginning incubation again.

PLO has a video of the second egg’s arrival. https://youtu.be/SoBhoQrwGWw?

Our new Mum at Collins Street. Gosh, let’s hope this family has good luck on this ledge. Life is difficult enough. They have a good spot save for the scalding heat that will come down on them. Hopefully Mum will move the chicks to the north end where it has shade.

There has been bonding and mating at Orange. Xavier would like another egg hedging his bets on not all eggs hatching.

SE33 asleep and SE34 watching for an adult to arrive with food at the Sydney Olympic Forest. SE34 did not have a lot of food yesterday so it was a great relief that it began the 29th with a nice big crop! The little one is still very skitterish around 33.

‘A’ gives us her narrative of events for the Olympic Park Eagles: “Although Lady and Dad were up and awake, dueting, at 6am, the littles were still waiting for breakfast at WBSE at 8am, and by 08:11 they were starting to bicker. SE33 stood up and leaned forward to stretch her wings. This impinged on SE34’s personal space so he bonked his older sister who immediately retaliated. Both then get stuck into some preening, as it is obvious they are itchy (just look at those feathers growing along the bottom edge of SE33’s wings, and a second line appearing higher up her wings, near her shoulders. Even SE34 is starting to preen relentlessly. Of course being this itchy always seems to make the eaglets a little antsy. 

Yes, the bonk from SE34 was foolish behaviour and got what it deserved, but the key thing here for me was that SE34 had the confidence to attack his older sister in the first place. He was not scared for long, though, going straight back to his preening without ducking and tucking. He just pulled away and then went about his business. That was a plus for me, as I have been wanting to see signs of a bit more of a feisty attitude from SE34. Perhaps this is the start of it. 

Both parents arrive around 08:42, one with a fish, pestered by a couple of smaller birds, who appeared to be dive bombing and otherwise harassing Lady and Dad. But Both parents are distracted and alerting, sometimes lunging towards the intruder birds. Eventually, with Dad on the perch branch fending off the smaller birds, Lady began feeding breakfast to the littles at 08:46. There is a black band around Lady’s round leg that I have not noticed before. What is it? Where did it come from and when? SE34 is offered the first four  bites of the feeding and takes them without any signs of intimidation. He is slightly closer to mum than is SE33. But the fifth bite is a bridge too far, and at 08:47:24 SE33 stands up. SE34 cringes away from his sibling and ducks his head/. Lady decides this would be a strategic moment to offer fish to SE33. Good call, mum. SE34 refuses the next bite, so mum feeds it to SE33. The same thing happens with the next bite. As Lady continues to feed SE33, SE34 is shuffling closer to mum, peeking at her as he does so. Lady keeps feeding SE33. At 08:49 SE34 lifts his head a little but is still too scared to eat. There is plenty of fish, so hopefully SE34 will get his turn to eat. 

Around 08:50 he dares to lift his head a little. He is watching mum closely but not asking for food. Lady is leaning across SE34 to feed SE33. This continued contact of SE33 from behind keeps SE34 on edge and very nervous to eat. At 08:50:50, he raises his head just a little too far, causing SE34 to beak him in the back of the head. He turns away and puts his head down on the nest again. Lady continues feeding SE33. He is not down for long though, and soon, SE34 is again watching Lady. Soon after 08:53, head still tucked, SE34 turns his back on the table. He has not had any breakfast so far. As Lady feeds SE33, SE34 is very carefully and slowly turning back around, until he is again facing the table. 

Lady pauses the feeding, with the fish rapidly disappearing, and SE34 continues to creep closer to her. 9am and SE33 eats and eats and eats. SE34 waits. By 08:46 SE34 is eatihng, his confidence growing with each bite he takes for which he is not punished by SE33; Lady returned about 40 minutes later and again fed SE34, so that eventually, both eaglets had good crops and had eaten well. “

Keep the Menhaden on your radar and the Canadian corporation Omega right beside them. If you live in the States, write to your Senator and the Senators from Virginia and get them to end the industrial fishing of Menhaden and create a clear three-mile distance from the mouth of the Bay! By doing so, you will help save the lives of the Ospreys who call Chesapeake Bay their home.

LGK shows up to feed the Royal cam chick! It will not be long until their little one takes to the seas, returning in five or six years. It is so amazing. https://youtu.be/c8DPhmweuQI?si=ZYARzkZ6ipw4MyzX

Hope and her two beautiful fledglings on the Snow Lane nest.

Charlie and Lola at the nest and C16 holding on. There is snow in parts of Montana. Hopefully it will not land on any of the osprey nests!

At Minnesota Landscape Arboretum nest, Dad is home and so is the juvenile. I have not see the female. Perhaps she is on migration?

At Boulder, it appears that Dad and the fledgling are still coming to the nest. No sign of the female.
