A Soaring Success: UK Red Kites Reintroduced to Spanish Skies

British conservationists have successfully played a crucial role in reintroducing red kites to Spain, helping revive a population that was on the brink of extinction.

In a remarkable conservation effort, over 120 British red kite chicks have been relocated to south-west Spain, aimed at boosting a dwindling population that now stands at fewer than 50 breeding pairs. This initiative follows the successful revival of the red kite in the UK, which saw the species rebound from near extinction. Conservationists are optimistic about the future of these birds in Spain, but challenges such as predation and illegal poisoning remain pressing threats.

A British red kite emerges from an aviary in the remote hills of western Spain and takes flight. At six months old, this is its first taste of freedom. Without a sound, it soars high in the sky above scrubland and within seconds disappears from view into a wooded valley in the distance.

This release marks a significant turn in a conservation story that has come full circle. Nearly four decades ago, red kites were deemed extinct in England and Scotland, with only a few pairs remaining in Wales.

In the late 1980s and early 1990s, conservationists introduced red kite chicks from Spain and Sweden to the Chiltern Hills in England, leading to a successful recovery. The species now boasts over 6,000 mating pairs in the UK, accounting for approximately 15% of the global population.

Dr. Ian Evans, a pioneer in the project, expressed early concerns about the releases but was encouraged by the first breeding pairs discovered in 1991, which demonstrated that the initiative could indeed succeed.

Now, British-born red kite chicks have been sent to south-west Spain as part of a four-year project aimed at reviving the local population, which has dwindled to fewer than 50 mating pairs, mostly due to predators like the eagle owl and human-induced issues like illegal poisoning.

The project has successfully relocated over 120 chicks, with about 30 transported each year from the UK to the Extremadura region of Spain. Conservationists hope to boost the local population and increase the chances of long-term survival.

Each chick is carefully weighed, measured, and fitted with a GPS backpack in a wildlife hospital in Madrid before being acclimatized in aviaries near the Portuguese border for two weeks. The release process is thrilling yet nerve-wracking, as the survival rate for newly released raptors remains precarious.

Despite the dedicated efforts, survival among the red kites remains challenging, with natural predators posing a significant threat. So far, only about a quarter of the relocated chicks have survived, prompting conservationists to adapt their strategies to improve outcomes.

The project has also shed light on the pressing issue of illegal poisoning, which has severely impacted populations of birds of prey across Europe. By addressing these threats, conservationists hope to see a resurgence of red kites flourishing in both the UK and Spain.
