Twelve young ospreys coming from former eastern Germany and from southern Norway are now in Switzerland at the reintroduction site of Bellechasse (FR). We will keep them in the specially constructed “hacking” cages until they are ready to fly. Right now they are adapting to their new home and their new environment and, like all growing teenagers, eating a lot!
Many thanks to ringers Holger Gabriel and Mario Firlo in Germany, and to Rune Aae of University College Østfold in Norway, who collected the birds and then took care of them (and us). They had to climb quite a few tall trees or high electricity pylons, and did this with great professionalism and efficiency. Thanks also to Daniel Schmidt, who organised the German operation and drove with us and another Osprey enthusiast, Günther Röber, all night to bring the birds to Switzerland.
We could never have done this project without the enormous amount of time and effort that have been provided by a large number of volunteers. We held a little ceremony at the General Assembly of Nos Oiseaux on March 19th in recognition for every volunteer that spent two weeks taking care of our birds on-site at the Bellechasse prison last summer. They all received a certificate thanking them for their personal engagement, as well as a little “low calorie” gift of… hazelnut biscuits. To remind them of how many packets were eaten during the memorable hours spent watching over the birds during the summer of 2015. Once again our thanks to all who have contributed to the project. Note too that it is still not too late to sign up to volunteer for the project for two weeks during the summer of 2016. We look forward to hearing from you on email@example.com!

Ospreys tend to be a little lazy, as they prefer moving into existing nests rather than building their own from scratch. This is why building nest platforms (see our first two built on November 2015) is an integral part of the project. We just finished building two more five star homes, one on top of a 30m tall Scots Pine and another on a dead tree. We are sure that once our birds return to breed, they will agree that these are top class places to nest!
The construction of these new nests required the climbing skills of Christian Grand and Adrian Furrer, helped by Michel Beaud, Emile Curty, Denis Landenbergue and Wendy Strahm as the ground crew. Building the first nest proved to be particularly challenging when it started to snow. Under such circumstances, we can’t help but admire the Ospreys that spend their winter in Africa and return to Europe soon after it finishes. At least they never have to shovel snow…
Whether it was chopping fish, watching and guarding the young ospreys, fixing radio transmitters, building nests, or many other tasks (not least of all fish tossing), to all the 2015 team we give a very big thank you!
An important part of our Osprey reintroduction project consists of building artificial nests to give the birds a helping hand when they return to Switzerland to breed. Once we had identified potentially suitable trees and obtained permission to build nests in their tree tops, Daniel Schmidt (pictured in action above) came from Germany to demonstrate and provide training in the art of building artificial nests that no Osprey would be able to refuse. Three Fribourg ornithologists who are also very experienced tree-climbers (Christian Grand, Pascal Grand and Henri Vigneau) helped Daniel to build the first nest, and then went on to build a second nest the following day. Michel Beaud, Emile Curty, Denis Landenbergue and Wendy Strahm also helped out in this operation.
Osprey nests are usually built on a tall tree with commanding views, so the birds can have a panoramic 360° view. Our first two nests were built at the top of 35m tall Scots Pines, a difficult operation so we were lucky to have good weather with little wind. It will probably take several years before our released birds return, and we are optimistic that when they do, they will find these custom-made platforms irresistible. Many thanks to the whole team for these first two beautiful nests, and for the many more that we are already planning on building.
After “escaping” from the prison grounds of Bellechasse when departing on migration on September 11, and then narrowly escaping death after being shot in Algeria by a poacher on September 16, PP5 has once again demonstrated his amazing capacity for escape. On October 11 Toufik Brahimi, the veterinarian who saved his life, went to examine and weigh him in preparation for his release planned for a few days later. PP5, however, had other ideas. After biting Mr Brahimi’s hand with his strong beak, he took advantage of the moment to push the door of the aviary open and to escape, immediately flying high above the mountains of Djurdjura until he was out of sight. While we had imagined a more controlled release back into the wild, we are reassured by Mr Brahimi who says that the bird had completely recovered from his wounds, had eaten well just before his escape, and was very dynamic. So dynamic in fact that he was not willing to spend any longer in captivity.
We will only know if PP5 has survived his ordeal if he returns to Switzerland in a few years’ time. However, as his blue plastic ring marked PP5 was damaged and had to be removed, he will be more difficult to identify. Indeed, this plastic ring may have saved PP5’s leg from being injured, as it was presumably damaged in the shooting. If we ever see a male Osprey with just a metal ring on his left leg returning to our release site it could well be our escape artist.
It has just been reported that a pair of Ospreys nested for the first time this year in the Alqueva reservoir, site of the Portuguese Osprey reintroduction project. However, it seems that the birds nested just across the border in the Extremadura region of Spain! The nest was spotted from a boat by Dr Luis Palma on July 19th, but the interior of the nest couldn’t be seen, and no birds were observed in the vicinity. However, Spanish wildlife guard Nicolás Durán and Isabel Asensio saw a pair accompanied by a juvenile on 30 August, indicating that the Portuguese reintroduction project has had its first success. The reintroduction of this species at the Alqueva Reservoir started in 2011 and is still ongoing. Congratulations to our Portuguese colleagues and friends for this wonderful result!
We recently received some shocking news from Algeria concerning one of our young ospreys called PP5 (nicknamed “Chernobyl” due to the markings on the back of his head which resemble a radiation symbol). This male had been found shot by a poacher in the region of the Djurdjura National Park, about 100 km east of the capital city Algiers.
The good news is that he is alive, thanks to the Park’s veterinarian Mr Toufik Brahimi, who operated on him and removed two shotgun pellets from his chest and the base of his wing. Mr Brahimi then contacted the Swiss Ornithological Station at Sempach, based on the inscription marked on his ring. We are now in direct contact with Mr Brahimi to discuss the best way to take care of PP5. He is fed daily with fresh fish and the latest news indicates that he seems to be on the road to recovery. Note that PP5 had left the Swiss reintroduction site on September 11, and had the misfortune to be shot on the 16th, exactly 5 days after his departure and some 1,200 km away after crossing the Mediterranean Sea.
It is not yet possible to know if PP5 will make a full recovery from his terrible ordeal although we are hopeful. Coincidentally Mr Brahimi remembered meeting us (Denis Landenbergue and Wendy Strahm) when we visited the National Park of Djurdjura in 2008. One additional reason for him, as if it were needed, to do his best to save what he refers to as “our bird”.
It is well known that only a third of young Ospreys usually survive to adulthood. There are many possible causes of loss: natural predation, ocean gales, sand storms, collisions with vehicles, wires or electrical lines, poaching or shooting through ignorance, etc.
On September 19, our last two young Ospreys of the 2015 reintroduction season left for Africa. The project team were watching PP1 and PP4 (named after the code on their colour ring) when the female suddenly spiralled high into the sky before heading south. A few hours later PP4 did the same. The photo above shows the difference in size between PP1, the female (to the left), and PP4, the male, on top of their release aviary. Since September 19 we waited several days to be absolutely sure that they had really left. It is common that young ospreys first make a “false departure”, which might last up to 2 or 3 days, before returning to the reintroduction site for more food before they finally decide to set off. Now that we are sure that PP1 and PP4 have really left we wish them a safe journey, hoping that they will avoid the numerous risks that all Ospreys face from the moment they are born.
The photo above was taken shortly before PP5 (bird to the left) departed on migration on September 11. We built two nests in front of the aviaries so that the young Ospreys could get used to seeing them. We were delighted when they started to perch on the nests.
In the wild Osprey nests are of course much larger and with many more branches than these. However, we built these nests during the peak of the July 2015 heatwave, which limited how much work we could do. We will do better for 2016!
Thanks go to Michel Beaud and Pascal Rapin for their help in building these nests with Wendy Strahm and Denis Landenbergue, as well as to the Etablissements de Bellechasse who built and installed the platforms.
