28. Astrid, Peregrine Falcon, Utica New York Falcon Platform. Mate of Ares. DOD: February 2025. COD: Unknown.
For over a decade, two remarkable Peregrine Falcons—Astrid and
Ares—soared above Downtown Utica, capturing hearts and inspiring our community. Together, they made history as the first known Peregrines to successfully breed in Utica and Oneida County
In 11 years, Astrid laid 44 eggs and, alongside her only mate Ares,
raised 32 young—a monumental achievement in the recovery of this once-endangered species. Sadly, Astrid disappeared in February of this year, but her legacy lives on.
29, 30: Two Eaglets. White Rock Nest, British Columbia, Canada. DOD: 14 May 2025. Cause: Unknown. Hancock Wildlife. Mum had cared for the eaglets since incubation alone. They were actually doing rather well. Some think it could be HPAI.
31. Youngest Osplet, MNSA Oceanside, NY. DOD: 23/24 May. COD: Hypothermia due to a cold weather event.
32, 33. Lima and Mike. Two Osplets. Waquoit Bay National Estuarine Research Reserve, Mashpee National Wildlife Reserve. Hatched on 20 May 2025. DOD: 29 May 2025. Cause: Weather event. Cold and lack of food..
34, 35, 36, 37. Four Osplets. Tweed Valley Nest 2, UK. Three belonged to Mrs O and the last to hatch to the New Female. DOD: 29 May 2025. COD: Starvation. The male disappeared and the females’s hormones meant that they were in brooding mood not hunting. All four perished shortly after hatching.
38, 39: Two Osplets. BUNDGoitzsche-Wildnis, Germany. DOD 26 May 2025 and 1 June 2025. Cause of Death: Predation by Red Kite. “Red kites are fast and skilled hunters. When an attack occurs very suddenly, the adults often have only a fraction of a second to react. Furthermore, wild animals instinctively weigh up whether a defense could endanger their own life or the remaining clutch of eggs. We suspect that the adults were taken by surprise and didn’t recognize the danger. They have been breeding successfully on this eyrie for so many years now, although they have never been threatened by red kites before; perhaps there is simply no strategy for dealing with it.
June 1, 2025: A red kite takes a second chick from the nest.
May 26, 2025: Drama for the ospreys: a red kite comes while the chicks are being fed and steals a chick from the nest. The attack lasts only seconds.”
40. Osplet. Second Hatch. Dewey Beach Lion’s Club, Delaware, USA. DOD: 1 June 2025. COD: Siblicide/Starvation. Lack of fish arriving at the nest.
41. Osplet. Third Hatch. Boulder County Fairgrounds, Colorado, USA. DOD: 5 June 2025. COD: Hypothermia. The weather turned cold and the baby could not get under Mum. All chicks had been well fed.
42. Osplet. Second Hatch. Stockton Osprey Platform, Galloway, New Jersey, USA. DOD: 6 June 2025. COD: Hypothermia. Mitigated by a bad weather event.
43. Osplet. Second Hatch. Captain Mac’s, Fenwick Island, Delaware, USA. DOD: 6 June 2025. COD: Starvation. Lack of fish arriving at the nest coupled with siblicide.
44. Osplet. Third Harch Loch Arkaig Nest 2 of Louis and Dorcha, Scotland. DOD: 8 June 2025. COD: Unknown. “Very mysterious, was feeding at 12.53, then not interested in food at 14.25 and last movement at 16.01. No doubt about its passing at 20.46, Dorcha flies off, the other two stand up and there’s just a sad bundle in the middle.”
It is so sudden and shocking, I doubt we’ll ever know. I imagine Dorcha will wait for a few days then take it out into the forest as she’s done before.
Timeline:
12.53.51 Chick3 is feeding, taking bites from Dorcha
14.08+ Chick3 is looking limp, lethargic, lying down, not interested in food
16.01.00 Chick3 can just be seen, back end peeking out from under Dorcha, movement of breathing seen but very weakly
20.46.19 Dorcha leaves, chicks 1&2 stand up and there is just a sad little bundle between them
20.47.56 Dorcha returns and leans down towards the chicks – has she noticed?
RIP Little chick3, we mourn your loss.. 27/5 – 8/6/2025

49, 50 SR 10 and SR 11. Eaglets. Surrey Reserve, British Columbia, Canada. Parents are Brit and Rey. DOD: 14 May 2025. COD: Pending necroscopy.
51. Osplet. Third Hatch. Pitkin County Open Spaces and Trails, Colorado, USA. DOD: 11 June 2025. COD: Unknown.
52. Third Hatch. Osplet. Ferguson Museum, USA. DOD: 16 June 2025. COD: Starvation.
53. Only Bob. Osplet. Minnesota Landscape Arboretum, MN, USA. DOD: 16/17 June 2025. COD: First-time parents had difficulty feeding their only chick to hatch. The chick starved to death. Is it called parental neglect? Or is it just sadness at inexperience? Mum began to brood her little deceased chick again. Dad brought in fish. They don’t understand what happened.
54. Osplet. Foulshaw Moss Nest 2, Cumbria, UK. DOD: 16 June 2025: COD: Not entirely clear but believed to have been stuck with nesting materials when Dad flew off. Cumbria Wildlife Trust posted the following: “Bad news from nest two 
We were super excited to share this video of three #FoulshawOspreys chicks on nest two with you today, but at some point yesterday afternoon, one of the chicks left the nest.
We can’t rewind this camera to see what happened, but our osprey volunteers think there’s a chance they were accidentally carried off the nest by dad Blue 476, as he had a clump of nesting material caught in his talons.
The positive side of this is that there are still two chicks on the nest, and they’re looking pretty strong. Without a third chick to compete with they should get plenty of food and grow up well.
It’s not the news we wanted to share with you today, but it’s the reality of life in the wild.”
55. Lesser Spotted Eaglet. Estonia. Nest of Milda and Madis. DOD: 21 June 2025. COD: Siblicide.
56. Osplet. Fenwick Island, USA. DOD: 25 June 2025. COD: Inability to cast pellet/dehydration due to heat dome.
57, 58, 59. Osplets. Saltpoint Osprey Nest, Washington, USA. Keo and Keke are the parents. DOD: 26 June 2025. COD: Nest Accident. A stick was brought to the nest that caused it to have a side break away and the three very healthy osplets tumbled to the ground where they perished. They will be buried under the nest. This entire incident was exacerbated by the early arrival of Canada Geese at the pair’s original platform. The ospreys made a makeshift nest on a light standard and sadly this is the result. It was the first time that Keke hatched three osplets.
60. Osplet. Second Hatch Island Beach State Park, NJ, USA. DOD: 28 June 2025. COD: Starvation due to the overfishing of Menhaden by Omega Corporation out of Reedsville, Virginia.

64. Makaio. Bald Eagle. West End Channel Islands, California, USA. Akecheta was replaced as Thunder’s mate for a short time. Her whereabouts are unknown, but it is hoped that she is with Akecheta on the mainland. Makaio then paired with Haku. Makaio is now MIA, status unknown. Last seen 3 June 2025. Possibly off on his own as this is the non-breeding season but he could have perished in a battle for the nest and territory.
65. Fully feathereed osplet ready to fledge. Dewey Beach, Delaware, USA. Pam Breci wrote in FB: “7/3/25 Dewey Beach baby passed away this morning. 5:36am its system shut down, did a small ps, had some imbalance, convulsions and passed away with head hanging over nest. For me, cause of death is Omega Protein!!! No one wanted to help this baby. I hope the parents are well and finding food. No parent seen yesterday. Last time baby ate was 7/1 12:24pm when dad dropped off fish. Last photo was before it passed. This baby should have fledged but a greedy company has destroyed this osprey season.”

Heidi reports: “Kent Island, Chesapeake: Sadly, there weren’t enough fish being brought to the nest by Tom and Audrey, and Little Boy 3 lost his struggle to survive at 47.5 days of age. He was so endearing, and we all loved him. Fly high with a forever-full crop sweetie. We all are hoping that he will still be given a name.”
