Oberhausen: first fledge!
Our male juvenile has fledged today. Even without us noticing. It was not until the very late evening meal that I missed one. Looking through all the photo's the last one with all three of them, was around 9:00 AM.( thanks Arjen)
So the little one fledged in the morning.
Once one is gone, the other two will follow very quickly. The parents try to lure the other two out of the nestbox by offering them very little food. Rations are down to one meal a day. Everbody who wants more can come out and get it.
So now that our little guy is gone it won't be long before the nestbox and ledge will be emtpy.
Let's just enjoy what time is left with these wonderful juveniles who have brought us all so very much enjoyment.
Derby Cathedral Peregrine project
It was a great day to watch the Derby eyases. They are doing so very well. All 4 of them. The youngest one is a keen little chap, getting himself more than enough attention and food. He's standing up front taking care he gets a lot. They are 4 beautiful chicklets, with a soft a fluffy appearence.
It's wonderful the projectmembers zoom in every once in a while (thanks Nick) so we can see them upclose.
I made about 300 pics, and it hard to make choice.
Here are 2 slide shows, one of the 18:00 feeding and another one of teh 20:00 feeding, Just watch and enjoy.

Rome: 33 days old, Bologna: fledge
After a day without food and very empty crops Aria brought in a fresh prey in the evening. The 2 juvi's where again that hungry that they fought over this prey with eachother and with Aria. I was very happy to see Aria did not let go this time, so the youngest one would be getting a good meal as well. At last. He is dominated by the other much bigger female. And does not dare to grab prey from her. It's amazing to see how he behaves to her, head turned away waiting until there is a left over item for him. This behaviour will not get him very far once they've fledged.
But these are babies, they need 3 good meals a day. Must be hard for Aria and Vento to get enough prey. But today they had al least one very big meal.
Today both Bologna juveniles fledged. And that is very soon. Let's hope everything goes fine with theM!
James River Bridge: 33 days old
the patches of remaining down feathers are becoming restricted to the base of the legs, parts of the wings, and perhaps parts of the back, as well as the crown. They are also becoming increasingly vocal and active around the nest area, to the extent that the adults rarely visit except to drop off food for them.
De Mortel: 22 days old
Again a day with a lot of food. Fresh pigeon is being brought in by S2 several times a day. She just loves to feed her chicklets. They are very fast in growing up. The beginning of the flight feathers getting loose from their protective shaft is becoming more eminent. The brown behind the eyses and on the head is becoming more visible every day.
Columbus Ohio: first hatch in progress
All signs are there that somehting is going on the the Columbus Ohio scrape.
Scout is very restless, she keeps listening to the egg she is keeping between her wings. It's exciting. We are all very anxious to know if the fourth egg will hatch. The one who was laid and had to wait 10 days before it was joined by the second one.

New Yersey
Fortunately things are going a lot better mow. The one chick left is doing fine.
NESTBOXNEWS
Nestbox News is an account of activity at a nestbox placed atop Mack-Cali Realty Corporation's 101 Hudson St., Jersey City, by biologists in the Endangered and Nongame Species Program.
We have had a difficult few days at the nest in Jersey City. Friday’s easterly winds with cold rain made for harsh weather conditions at a time when the nestlings were just 10 days old, a time when they don’t yet have a thick downy plumage. It was somewhat coincidental that we had scheduled a nest visit for Friday, with the purpose of administering medicine to ward off trichomoniasis, a pigeon-borne disease that can infect and kill young chicks. Biologists removed the four nestlings from the box and took them inside to check them over. While all were damp and somewhat subdued, one of the four seemed near-death, very cool to the touch and mostly unresponsive. We administered medication, along with small chicken pieces, to three of the nestlings, and they seemed okay. We decided to take the fourth nestling to The Raptor Trust, and we hoped he would live that long.
A couple of surprises: the youngster we took away with us began feeling better once he was warmed up in the truck. The transformation was amazing, from cold and listless to head-up and looking for food. This was an unexpected but welcome development, and, assuming he continues to thrive, we hope to return him to the nestbox in about a week.
The really sad news is that, with the continuing cold and driven rain, the female was not able to keep all three remaining nestlings warm, and one of them died by Friday evening. The female was trying valiantly to keep all of them under her wings, but even she seemed soaked by the rains. To make matters worse, viewers tuning in Saturday morning saw two dead nestlings, a second one succumbing during the night. The sun came out and the remaining chick was moving about, and the adults were feeding and brooding it, but they were also trying to brood the two dead chicks.
A decision was made to remove them so that the adults would focus their efforts on the remaining live one, and to try to identify the cause of death. Mack-Cali engineers removed the bodies for future examination, and we greatly appreciate their timely assistance and their courage in facing the defensive adults. On Sunday, the sun came out for a while in the morning, and the nestling alternated between resting, feeding, sunning and getting brooded by the adult. All seemed well.
The weather forecast for Monday seems a repeat of Friday’s harsh weather, but the adults should be able to cope with the conditions with only one young to protect. While we were there Friday, both adults were very aggressively defending the nest, and we kept our time on the roof as short as possible. We were able to see that the male is the same as previous years, with “*2/*6” on the bicolor leg band (originally banded in 2003 at the Riverside Church in Manhattan). Behaviors suggest the female is the same as well, thought we’ve never been able to read her band.
Brighton Sussex Heights: 15 days old
Around day 15, the chicks are beginning to enter the "hunchback" phase, during which they are often seen in the pose above, with their feet splayed out in front of them and their head angled forward.
Oberhausen: meal for 2
When one of the juvi's has fledged, the parents want them all out. That is much easier for them to take care of the bunch. The one who fledged get's lots of food, outside on the ledge or wherever he is. The other ones have to wait and don't get more then one meal a day. That is the way to get them out of the nestbox into the air. So the 2 females had to wait all day till after 7 for their meal.
Wonder when they will fledge, maybe as soosn as tomorrow.
Will miss them, these 3 great creatures.
