The skies of Castilla y León have left a historical imagesomething that had not been seen for a long time in our country: a native baby eagle flying over the territory. The specimen of this bird of prey was born on Spanish soil a few months ago, early mayand has already taken flight, as has just been said reveal The Confidential. Something like this hadn’t happened in a long time. That a species that was supposed to be extinct in the Iberian Peninsula since the 19th century manages to recover ground is usually positive news, but in the case of the eagle it comes clouded by something else: controversy.
There are those who believe that its reintroduction in Spain is a “historical milestone”.
And who thinks it is a blunder.
First of all, what is the eagle? A bird of prey that stands out for its enormous size. With its wings extended it can reach 2.4m wingspan and usually measures between 80 and 90 cm long. His name appeared in a list published years ago by the Ministry for the Ecological Transition and Demographic Challenge (MITECO) with extinct species susceptible to be reintroduced. After all, there are those who consider that the eagle, which continues to live in Scandinavian countries, it disappeared from the peninsula among the 19th and 20th centuries due to the degradation of their environment.
How did you return to Spain? Thanks to Proyecto Pigargo, a plan released in 2021 with the approval of the Principality of Asturias, the Cantabrian Government and above all the support of MITECO, which invested more than 300,000 euros in the recovery of the species. In August of that same year was announced the arrival of almost a dozen young specimens born in Norway that were introduced in Pimiango, in the municipality of Ribadedeva (Asturias). As time went by, more birds were released until add 25. Of them survived about 17almost all (12) paired.
And have they bred yet? Yes. The news I advanced it on September 18 GREFA, the group that has promoted the reintroduction of the species on the peninsula. In a statement The group explains that the calf was born in May in the north of Castilla y León, in an area that had been identified as “optimal for the species”, although GREFA has not specified the exact location “to avoid any disturbance.”
“The birth of the first European eagle chick in Spain represents a historic moment for nature conservation in our country,” celebrate the association before highlighting the collaboration of the Junta de Castilla y León and the “technical support” of both MITECO and agents of the autonomous community.
Perfect, right? It depends on who you ask. If we listen GREFA is “a historic milestone for biodiversity in Spain and Europe”, the result of a well-studied plan, which accumulates hours of work and has achieved the support of IUCNthe International Union for Conservation of Nature.
The group insists that it is the first breeding after “the extinction” of the species in Spain and highlights “the success” of having achieved a chick in a few years with 25 specimens released. “An exciting and motivating result that allows us to hope for more views next season,” celebrate.
Don’t everyone think that way? No. The launch of the Pigargo Project may have generated expectations at the time, but it certainly did not achieve something equally or even more important: scientific consensus. Already in 2021 there were voices that warned that releasing copies in Spain meant “a bad idea”. In fact, that was the key message of an article published in The Conversation by three experts from the University of Oviedo in which they pointed out the weak points of the program and questioned whether the eagle is really a native and extinct species. The controversy escalated to such a point that the central government and the autonomies that had initially endorsed the project they decided to back out after just two years.
What arguments do they use? GREFA recalls that the releases of eagles that began four years ago in Asturias had the endorsement of the IUCN and the species was included in the list of extinct fauna prepared with the endorsement of the committee of scientists that advises the ministry. Not only that. The group defends that the birth of the first baby in the wild in Castilla y León a few months ago proves the adaptation to the environment of a bird of prey that, argues“contributes to keeping under control” other species that can damage ecosystems, such as carp.
“Thanks to its scavenging habits, the European sea eagle plays an important role as a ‘health police’, helping to control the spread of diseases by effectively removing animal corpses from the environment,” they point out from the entity.
In fact, GREFA trusts that the birth of the first chick marks a turning point in the program and will allow it to recover the institutional support that it has been losing in recent years. “We hope that this historic event encourages strengthening or resuming support for the project, especially in the case of the Principality of Asturias and the Government of Cantabria, whose initial collaboration was fundamental although they later withdrew it,” Ernesto Álvarez slidesits president.
And what do the critics say? They go to the root of the approach and question its most basic premise: that it has really been proven that the eagle is a species native to the peninsula. “To consider a species as extinct, the evidence must be irrefutable. In the case of the eagle that does not happen. The documentation that has been used for its classification as an extinct species is reduced to some reports on archaeological remains, several citations of solitary specimens and dubious signs of breeding,” he points out. the article published in The Conversation.
One of them, Germán Orizaola, Ramón y Cajal researcher in Zoology, warned in 2023 in statements to The Country of the risk that the initiative may pose for other birds. “A species is being released here that has had no place in the ecosystem for thousands of years. It can compete with the golden eagle or the bearded vulture for food and drive them out of the nesting areas. It has been done without a scientific basis.” There are those who even has demanded the immediate withdrawal of the eagles released in Asturias precisely because of “the risk” that the birds represent.
Is it a unique case? Not at all. The European eagle is not the only reintroduced species that has generated a stir. Something similar has happened with the european bison. A year ago, dozens of experts from 25 universities advised against its introduction into the peninsula, and they warned: “It is impossible for it to replace the bison represented in Altamira, known as the steppe bison, because it is a different species, definitely extinct, that lived in a habitat known as the mammoth steppe that also does not exist today.” A similar debate It was also recently reopened with another protagonist: the Przewalski’s horse.
