The species, which was once found in abundance across North Africa, Southern and central Europe and the Middle East, is now critically endangered as a result of hunting, habitat loss, pesticide poisoning and an increase in construction works around their preferred nesting sites.
The northern bald ibis has undergone a long-term decline and more than 98% of the wild population has been lost, putting the birds on the very brink of extinction. Experts estimate that only 115 breeding pairs remain in the wild – in small populations in Morocco and Turkey. The species was last seen in Syria in 2014 and it is feared that population is now extinct.
Collections director at the zoo, Mike Jordan, explains:
“The breeding of seven northern bald ibis chicks is a remarkable addition to the endangered species breeding programme and a welcome boost to their global numbers. Our team have been weighing the chicks daily and carefully monitoring how often the parents are bringing them food – as each one is absolutely vital to the future of the species.
“Sadly, the species has been extinct in Europe for more than 300 years and since joining the reintroduction programme in 2007, we’ve made great efforts to breed these birds so that they can eventually go on to be released back into the wild. We hope that by reintroducing birds back into a safe, secure and monitored site in southern Spain that they will hopefully go on to successfully breed and give the species once more a foothold in Europe.
“Breeding such critically endangered birds successfully over the years is a huge achievement and this remarkable project really shows the important role zoos can play in conserving species that face a wide range of threats, and are on the edge of extinction.”
The International Union for the Conservation of Nature (IUCN) has listed the Northern bald ibis as critically endangered on its red list of threatened species since 1994. We joined the reintroduction programme in 2007 and have been working closely with Jerez Zoo, the Andalusian government and other conservation institutions across Europe to re-establish the species in Europe and help prevent the birds from disappearing from the wild altogether.
