I hate this. :cry: I know it's nature or man causing nature to act differently than usual but I hate it, anyway. :cry:
The woods are lovely, dark, and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.

Thanks so much to everyone reporting on this nest. Although I have not been able to post so much I have read and followed the posts every day.

I too am devastated by the recent events. It is so sad, and now so predictable.

I don't know if there is any possible solution, but I also pray that for some reason Teo and Vita may abandon this nest and find another.

July 13th

4:27am. The nest is empty. :cry: :rant:

I have read the posts about the terrible loss of the 2 most beautiful chicks, fat and happy, cared for lovingly by Teo and Vita.
Like, sova, I cannot say what I want to say right now.
Like, Asteria, Said what was posted on YouTube, I wonder if this Goshawk, is not sent on purpose.
This same loss cannot keep happening year after year.

my heartfelt condolences to everyone,I know how much you care about this Osprey family.

Da aber die Uhus offenbar nicht lange überleb-
ten und in der nachfolgenden Zeit auch anderen-
orts, wie 1952 bei Rheinsberg und 1954 in der
Dubrow, wo damals weder mit Uhus noch im
Sommer mit Seeadlern zu rechnen war, Fisch-
adlerrupfungen gefunden wurden, mußte wei-
ter nach einer Erklärung gesucht werden. Im
Wolfgang Baumgart
Gibt es eine symbiotische Beziehung
zwischen Fischadler und Wanderfalke
gegenüber dem Habicht zur Brutzeit?
letztgenannten Fall handelte es sich sogar um
einen Altvogel.
Die Bedeutung des Habichts als Horsträuber
beim Fischadler erkannte Otto Schnurre (1956,
1958) erstmals bei seinen Untersuchungen auf
dem Darß. Hier konnte er ihm 1952 das Schla-
gen von zwei jungen Fischadlern, 1953 von fünf
Jungen (aus zwei Horsten) und 1954 von vier
weiteren Jungadlern aus drei Horsten nachwei-
sen. 1955 kamen zwei weitere junge Fischadler,
einer als Nestling und ein voll erwachsener, dazu.
Entsprechende Rupfungen waren zumeist auch
mit Habichtsfedern „dekoriert“.

But since the eagle owls apparently do not survive long and in the following time also other places, such as in 1952 near Rheinsberg and 1954 in the Dubrow, where at that time neither with eagle owls nor in Eagles were to be expected in summer, fish eagle plucking were found, had to an explanation should be sought. in the Wolfgang Baumgart Is there a symbiotic relationship between osprey and peregrine falcon against the goshawk during the breeding season? The latter was even a case an adult bird. The importance of the hawk as a hawk Otto Schnurre (1956, 1958) for the first time in his investigations the Darß. In 1952 he was able to give him his sleep gen of two young ospreys, 1953 of five Boys (from two clumps) and in 1954 from four further young eagles from three eyries can be sen. 1955 came two more young ospreys, one as a nestling and one fully grown up, too. Corresponding plucking were mostly also "decorated" with hawk feathers.
Also ...
Hier leistete Otto Manowsky (in Fischer
1980), der nach Wilhelm Rieck Mitte der 1970er
Jahre die Untersuchungen fortführte, dann ei-
nen maßgeblichen Beitrag. Wie bereits von
Schnurre aufgezeigt fällt es dem Habicht offen-
bar nicht schwer, Fischadler-Horste anzufliegen,
einen Jungvogel zu packen und mit ihm in eine
Deckung am Boden, oft in unmittelbarer Nähe
des Horstbaum-Stammes abzugleiten, ihn zu tö-
ten und zu rupfen sowie vor Ort zu verwerten
(kröpfen), ohne daß die adulten Fischadler et-
was tun können. Für einen Abtransport zum ei-
genen Horst ist der Kadaver am Anfang sicher
zu schwer und zu sperrig.
Die Fischadler-Nestlinge sind offenbar –
und dafür sprechen zwei Rupfungsfunde vom
27.08.1954 – besonders gefährdet, wenn sie fast
flügge von ihren Eltern zeitweise allein gelas-
sen werden. Obwohl die Meinung vorherrscht,
es wären vor allem die wesentlich größeren Ha-
bichtsweibchen, die den Fischadlern gefährlich
würden, steht nach beiden Gewährsleuten zwei-
felsfrei fest, daß auch Habichtsterzel dazu in der
Lage sind.
Gt
Here Otto Manowsky (in Fischer 1980), which was named after Wilhelm Rieck in the mid-1970s Years of continuing the investigations, then one a significant contribution. As already from When the purr is shown, the hawk is bar not difficult to fly to osprey clumps, to grab a young bird and into one with him Cover on the ground, often in close proximity of the Horstbaum trunk, to kill him ting and plucking as well as utilizing them on site (crop), without the adult ospreys et- what can do. For transport to one In the beginning, the carcass is safe with the Horst too heavy and too bulky. The osprey nestlings are evidently - and this is supported by two plucking finds from 08/27/1954 - particularly endangered when almost fledged left alone by their parents at times be sen. Although the prevailing opinion it would be the much larger ha- beaks who are dangerous to ospreys according to both sources, there are two rock-free, that also Habichtsterzel in the Location are.
Teilweise erfolgte
das bereits durch Meyburg et al. (1995) mit
dem Ergebnis, daß Fischadlerbruten auf Hoch-
spannungsmasten nicht nur deshalb erfolgrei-
cher sind, weil sie seltener abstürzen, sondern
auch, weil die Jungen in Horsten auf Gitterma-
sten vor dem Zugriff des Habichts sicherer sind.
Das relativiert sich aber, weil inzwischen auch
nachgewiesen wurde, daß Habichte selbst Horste
auf Gittermasten plündern und Fischadler davon
nicht ausgenommen sind. Eine diesbezügliche
Dokumentation von Sabine Kunze und Susanne
Grießbach vom Informationszentrum für Um-
welt und Naturschutz HAUS AM SEE Ortsteil
Schlaitz, 06774 Muldestausee) ist hier eingefügt.
Hinzu kommen, so Sömmer (pers. Mitt.) auch
weitere, individuell wechselnde Faktoren. Man-
che Fischadlerweibchen verteidigen ihre Jungen
so energisch, daß Habichte nicht zum Zuge kom-
men, während es wiederum auch solche gibt, de-
nen der Habicht die Jungen regelrecht unter dem
Körper, ohne effektive Gegenwehr, hervorziehen
und rauben kann.

Partly took place that already by Meyburg et al. (1995) with the result that osprey broods on high voltage pylons are not only successful are safer because they crash less often, but also because the boys in Horsten on lattice are safer from the hawk's access. But that is relativized, because meanwhile too it has been proven that hawks themselves clumps plunder on lattice masts and ospreys away are not excluded. A related one Documentation by Sabine Kunze and Susanne Grießbach from the information center for world and nature conservation HAUS AM SEE district Schlaitz, 06774 Muldestausee) is inserted here. In addition, according to Sömmer (personal communication), too further, individually changing factors. Man- Cheerful female ospreys defend their young so energetically that hawks do not men, while there are also those who If the hawk is literally under the boy Pulling out bodies without effective resistance and can rob.
Im Erbeuten von Greifvögeln gibt es zudem
zwischen einzelnen Habichtspaaren und -popu-
lationen erhebliche Unterschiede. Meist geht es
um Einzelfälle. Doch auf dem Darß stieg ihr An-
teil bei offenbar geringem Beute-Angebot auf
10% (17 Greifvögel unter 170 nachgewiesenen
Beutetieren), darunter neben Fischadlern noch
Mäusebussarde, Schwarzmilane und Sperber.
Dabei bieten die weit vorstreckbaren Fänge des
Habichts wohl den Vorteil, daß er mit ihnen er-
griffene Greifvögel (auch Fischadler) bei ihrer
möglichen Gegenwehr auf Distanz halten kann
(Schnurre 1956).

In capturing birds of prey there is also between individual pairs of hawks and popu- significant differences. Most of the time it works about individual cases.

Well, I find some of the comments here very strange.
And I know why I usually push away the chat on YouTube immediately.

The animal world is not about the cuteness factor !!!

All animals have the same right to food. Last year I already suspected that it could be a lack of food supply that drives the Goshawk so massively in Osprey nests. But do you want to blame the Goshawk? It would be better to see the events in the bigger picture than to be angry about them and blindly judge them.

It will continue for Teo and Vita.

The events are tragic, but they are repeated for the third time, so it is predictable and preventable

The situation is simple, just answer the question:
the goal of osprey couple is to grow up the chicks.
the goal of goshawks is to get food.
what is the goal of people and on whose side they are in fact? what would they do if it was not an osprey couple but hens(goshawks usually kill hens one by one and drop them on the ground)?

Once I read a book where the kids found a thrush nest and followed how the chicks hatched and developed. Until someday their grandfather saw those chicks and fed them to his cat. When shocked boys asked him why he did it, he answered: "So what? The cat also needs food! Why should I pity those chicks, there are many of them!" The situation now seems to be pretty similar with the one from that book.

I don’t know, Polly, what to answer, or what is the answer. To me it appears that the Goshawks have had the upper hand in deleting the Ospreys. I don’t know if the ornithologists ring the goshawks, or keep count. Maybe the Osprey chicks are thriving in other areas of Latvia. :puzzled:
Yes, I do think that the Osprey chicks are cute. I am not sorry for my opinion. I have watched many different nests in 15 years , and not seen this type of failure to fledge. True, that I am mainly interested in bird nest that have a good supply of food, and without much drama. I stay away from some nests.
I do understand your point of view, and hope that you can understand mine.

The prey spectrum of the Goshawk is quite broad. They don't just prefer chickens ...
What about rodents, rabbits. Generally smaller mammals? Goshawk they would take. Is there enough of this food for goshawk?
If not, why?

Teo and Vita would have the option of brooding elsewhere. It would be the next step.
Unfortunately, breeding sites are also becoming scarce. But that is not the fault of the Goshawk either.

If prey is left lying around, the goshawk has likely been disturbed. There are animals like fox, marten and so on that can disturb him on the ground and it leads to the goshawk having to let go of it. Sometimes he has to work on the prey to be able to transport it.
It has nothing to do with pure lust for murder.

The role of people should not be condemned but rather observed and questioned fairly.

Once I read a book ...
Far-fetched.
Once upon a time it was sea eagles who plundered the nest. (White-tailed eagles are natural enemies of the Osprey) ... now there is the Goshawk. Elsewhere, owls kill the chicks or now also ravens like in another nest.

What do you expect? What would your solution be?

Remember what was done in Hog Island when the GHE took away two chicks from osprey nest and how the third one was saved in 2019. Also: a WTE takes one chick and leaves. It doesn't kill all the chicks every year like goshawks do(that can be called ospeycide).

We observe nests that often have different natural conditions. We never see everything @asteria.
But many believe that they can judge from this insightful observation.

I would still like to know what you propose.
In the last year there have been some terrifying ideas ....
Where should it lead to? There are enough raptor murders!

Ospreys are not endangered. Even if they are not widespread regionally. And even if the death or robbery of every animal hurts.
We do not decide whether it is necessary to intervene! When WTE plunder entire hawklet or swan nests, such a discussion never arises! Because these prey animals are / were not camera favorites! Something is taken with pity, but no discussions are started.

There are dedicated specialists on site who know what to do. Whether something is to be done ... who not only observe a situation but know the whole picture.

We should reduce ourselves to observing.

Last year nothing was done. First of all I would equip goshawks with transmitters and follow their fligts and places of huntering. Then, after their tracks are known, it would be possible to think how to chase them away from the territory. So many birds of prey: buzzards, WTE, ospreys, spotted eagles have tranmitters, why goshawks never get them when they are really necessary?

Asteria, I like the transmitter idea!
:thumbs:
The ornithologists, will probably consider this. They have put their time, energy and money, into securing locations, building platforms, getting expensive cameras and solar power batteries etc. I don’t think that their goal was to feed a family of goshawks, 1 or 3 Osprey chicks, per season per nest.
If the goshawks are lacking prey and need to feed their family, why wait till the Osprey chicks are a certain size? :puzzled:
When you are hungry now, how can you wait? :rolleyes:

I watched a Spanish nest camera this season, of a Booted Eagles. Miraculously, both chicks were thriving, even though the smaller chick was very much smaller. But a fighter and smart! It had figured out how to survive with the older much larger chick.
Anyway, the goshawk attacked in the evening and made off with Both Chicks, in one swoop! Granted these birds do live in the forest.

I don't like what I'm here reading about the Goshawk! The goshawk is a native bird. He belongs in our woods. It is bad enough that goshawks are illegally hunted by pigeon fancier and hunters. For me the goshawk is a fascinating beautiful bird!
It would be completely sufficient if humans finally understood that they must not intervene in nature, because this creates an imbalance in nature!
If you are looking for someone to blame, look in humans, not animals. No matter which animal!
