The Northern Bald Ibis: Conservation Success and Challenges

Historical Background
After the northern bald ibis vanished from Europe more than 300 years ago, many assumed that 16th-century drawings showcasing its gleaming plumage and long, arching beak were merely products of imagination.
These birds, once abundant across three continents, were so revered in the ancient world that they are represented in hieroglyphs, symbolizing the word akh, meaning “spirit.”
Population Decline and Conservation Efforts
By the 1990s, the northern bald ibis was recognized as one of the rarest birds globally, with its wild population dwindled to just 59 pairs, all situated in Morocco due to hunting, habitat loss, and pesticide use.
However, thanks to persistent conservation initiatives in Morocco, the population has rebounded to over 500 individuals, allowing the IUCN Red List of Threatened Species to reclassify its status from critically endangered to endangered in 2018.
Moreover, due to a pioneering reintroduction program, these ibises have resumed their migrations to Europe for the first time since the 1600s, with a managed population of about 270 birds.
Current Habitat and Diet
The northern bald ibis now occupies a small fraction of its former range in Europe, the Middle East, and North Africa. Typically, breeding colonies make their homes in cliffs, rocky outcrops, and even urban ruins. Their diets consist primarily of insects, worms, and larvae, although adaptability is key for foraging in their often-remote habitats.
Conservation in Morocco
Morocco is home to the largest remaining wild population of the northern bald ibis, largely due to extensive conservation efforts. The establishment of the Souss-Massa National Park in 1991 played a crucial role in protecting nesting and feeding areas. In 1994, a research program was initiated to monitor the endangered species, and as per the IUCN, the Moroccan population, which does not migrate seasonally, is currently stable.
Migration Challenges in the Middle East
Historically, the northern bald ibis thrived in Turkey and Syria, known for its vast migration route to and from Ethiopia, traversing through Eritrea, Sudan, Saudi Arabia, and Jordan. Unfortunately, populations sharply decreased in the 20th century, leading to the assumption of regional extinction when no birds returned to Syria in 2015.
Reintroduction Projects in Europe
Efforts are underway to reintroduce the northern bald ibis to various parts of Europe. One notable project in Andalusia, Spain, initiated in 2004, involves adoptive human parents hand-rearing chicks born in captivity before their gradual release into the wild.
Unique Migration Initiatives
Another innovative effort to establish a migratory population in Austria and Germany is being led by biologist Johannes Fritz. In 2003, aiming to teach captive-bred birds the migration route, Fritz employed ultralight aircraft to guide the flock from Germany to Italy, drawing inspiration from the film “Fly Away Home.”
Ongoing Threats and Future Outlook
Today, while a majority of European ibises are showing independence from human guidance, the species faces multiple threats. Their dependence on insects makes them vulnerable to pesticide use, which disrupts their food supply. Furthermore, poaching accounted for approximately 17% of the migrating population in 2023, while climate change is necessitating variations in migration timing, presenting additional challenges along their migratory routes.
