Amidst the joy of Peregrine Falcon eggs in Australia at both Orange and Melbourne, the loss of dear Lindsay, the eldest of the two siblings hatched at The Campanile on the grounds of the University of California-Berkeley, remains heavy – a real heartbreaker. From the news it is apparent that Lindsay died several weeks ago; her body just being found today. She was last seen on the Campanile on 5 August precisely three months after she hatched on 5 May. A life cut way too short.
Lindsay was one of a two-part miracle. Lindsay’s Mum, Annie lost her mate Grinnell when he was killed after chasing an intruder away from The Campanile. There was worry that there would be no chicks this season. Alden arrived in 5 or 6 hours hours (already a friend of Annie and Grinnell’s) and offered to help Annie incubate the eggs and take care of the chicks. We rejoiced at the love the two siblings had for one another, when they played, and when they chased moths. They grew strong and they flew. It is with such deep sadness that we say goodbye to Lindsay today. Fly high, Sweet Girl. Soar to new heights you never imagined.
Here is the full announcement from Cal Falcons. It appears that Lindsay’s death, from the evidence found from her body, was killed by another raptor.
It is heartbreaking. Lindsay had such potential and, of course, it is very possible that she was the last chick our beloved Grinnell fathered. She brought us such joy! I would like to share a few images of this remarkable falcon moving back in time from the last sighting of her on The Campanile on 5 August to the day she hatched.
Lindsay and Grinnell, Jr adopted many of the quirks of Alden including loafing. Annie has perfected it!
Annie and Grinnell, Jr playing together at The Campanile. The two siblings seemed to really enjoy playing with one another, something that I have not seen for a long, long time. It was refreshing.
Lindsay on the roof of the library on 18 June after fledging. Just look at this exceptionally beautiful juvenile. Stunning.
Do you remember banding day 27 May (on the right)? Lindsay was frightened but quiet. Alden would not stop being loud! Lindsay was still sit ting with a not so scared look on her face in early June.
Lindsay was also sitting in that same pose on 22 May.
Hatch day for Lindsay, 5 May. Grinnell wants to come and help. Annie is not sharing – yet – but she will and each of us will rejoice watching this wonderful family.
‘H’ just sent this press release on Lindsay. Thank you, ‘H’. Just made it before I hit send! Grateful.
From the Mailbox:
‘M’ writes: What do you think about this from Dyfi project? I am not sure I would pass off some of that behaviour as just “playing”, at least not based on how the smaller chick reacts. Wondered about your view, based on your study of third hatches.”
For transparency, I posted the information from Dyfi in one of my blogs. Emyr Evans has a long history with the Dyfi Nest in Wales. I have great respect for him but, in this instance, I choose to disagree.
In the UK Osplet deaths are generally attributed to either very poor weather in the early days after hatching or lack of prey, starvation not siblicide. There is little history of siblicide; there are so few breeding pairs and chicks compared to North America. This year, however, we did see it at the Loch of the Lowes Nest. It was rather horrific treatment of the third hatch that was killed by the eldest during a period of low prey delivery.
As you are aware, my research is on siblicide and, in particular, the success of any third hatch osplets vs the other two siblings. Because I track the juveniles long term this is limited to those that are ‘ringed’ and/or ringed with SAT tracking. My findings also rely on the good fortune of someone seeing the juveniles in the future and providing that information to various data bases! In my experience, the aggression shown by older siblings ranges from mild displays of dominance to more serious concerns that seem to taper off around the age of 26-28 days. Serious aggression often ends in the death of the smaller weaker sibling. There is much research to support the fact that it is not always about food. Sometimes it is just dominance.
‘M’ this, in my opinion, is not play. It is establishing the dominant bird on the nest. The dominant bird will eat first and if there is little food it will be the only chick that eats. Had food been scarce the treatment might have escalated but, thankfully, it didn’t. Gender may play significant roles also with the females requiring more food to grow 1/3 larger and feather a larger body. Thus, the females, especially if they are the first hatch, tend to be more aggressive.
Multiple times this year we have seen the third hatch killed by the eldest sibling and sometimes in conjunction with the middle one. As mentioned, this happened at the Loch of the Lowes this year when food was scarce. It also happened at the UFlorida-Gainesville Osprey nest amongst others. It also happens on eagle nests and other species. However, there appears to be a higher rate of siblicide among North American Ospreys than those in the UK. It is likely that these numbers reflect the higher population of Ospreys in North America. In addition, the lochs are full of fish and there are restrictions on many of them to prevent human intrusion during the breeding season.
In the News:
We are going to start with some fantastic news. When I lived in the UK, I studied in Leicester but lived in Lincolnshire and Belvoir (pronounced Beaver) Castle was a regular haunt for me – so close to where I resided. For the first time in 200 years, we have Ospreys breeding on top of Belvoir Castle! Oh, my goodness. I am delighted. Here is the BBC News report.
There is more news coming in about the sad state of the White-tail Eagles on Mull Island — known internationally for the birds and their nests.
Bird Flu is also killing Black Vultures. Deaths from migration, Avian Flu, human disturbance and killings, fires, habitat loss, lack of food…how many of our raptor friends will be left?
There is a lovely documentary on YouTube on the return of the Black Storks to Germany in the 1980s. The cinematography is excellent as is the narration. So much to learn – 53 minutes. Find a nice quiet time to watch!
The 367 Collins Street Falcon Cam in Melbourne is up and running. So far there are 2 eggs!
Here is the link to the camera:
As you will be aware, the first egg of the season for Xavier and Diamond at their scrape in Orange was laid at 0713:48.

Xavier comes to the scrape to relieve Diamond. A short bonding ritual takes place before Diamond flies off.

Xavier carefully rolls the egg.
Everything is alright with the world. Oh, what a joy to finally see the first egg for Diamond and Xavier. Let us all hope that their year is as successful as it was in 2020 with the hatch of the ever adorable Izzi.
Here is the link to one of three cameras for Xavier and Diamond:
I am so used to the Ospreys in the UK and the Dads bringing in a fish right before or when the sun is rising in the morning. That first fish delivery for SE29 and 30 at the WBSE nest in the Sydney Olympic Forest did not come until 12:31 today. Thankfully the chicks were civil and it was not huge but was a good size.
Images from early morning to feeding.
Early morning preening of those itchy feathers.
Beautiful Lady listening and waiting for Dad to bring food to the nest.
SE29 and 30 watching Mum aerate the nest. Just look at how carefully they are looking at her every move. This will imprint in their mind’s and they will know to aerate their own nests.
Finally, a fish has arrived!
Things appear to be going good at the Port Lincoln barge except for Mum making cries for fish. On occasion Dad has flown in eaten more than his fair share while Mum is fish calling. He then delivers the remainder to her. Come on Dad! Dad is taking his turns incubating.
Oh, it seems so long until 19th of September – may the time pass quickly! There is nothing cuter than nestlings a couple of days old.
Checking on Kaia’s transmission. She remains in Belarus. On the 25th of August she flew 123 km. She is now near the village of Liaskavicy. It is in an area that is part of the wetlands of the Pripjat River. There is a national park and the area is considered to be quite safe for Kaia.
Karl II is looking a little tired. Thanks to Urmas the supply of fish continues so that he can feed the four Black Stork fledglings. Soon they will fly and hopefully Karl II will have some days to recover and gain some weight before he leaves. Of course, when they do depart we shall all be worried for them. I wonder if by some means Karl II and the children will meet with Kaia and decide another route to their winter home???
It appears that all of the White Storks from the nest in Mlade Buky, The Czech Republic have left for their migration. It is raining heavily and both of the nests of Bukacek and Betty appear so lonely. Safe travels dear family.
Suzanne Arnold Horning has caught L2 on the Cornell Campus! So happy she is here with us. In the history of the nest, it seems that the 28th of August is the last day to see fledglings in the past. Enjoy these moments then with our first fledge of the year. Gosh, she is beautiful. We know that she is catching her own food – she was the second of the fledglings to do so more than a month ago. So all is well with L2.
It is Friday. A friend sent this to me to cheer me up because of Lindsay. I did giggle…love those sour worms. Thank you ‘S’.
Thank you so much for joining me today. If you have any questions, you can send them through the comments page or through e-mail. My address is firstname.lastname@example.org Have a fabulous Friday! Take care of yourselves. See you soon.
