The bearded vulture, a large bird with a wingspan of nearly 2.8 meters, is often seen during high-altitude hikes in mountainous regions. Unlike most scavengers that feed on meat, this bird has a unique diet that consists mainly of bones—about 80% of what it eats. To make the bones easier to digest, the vulture drops them from great heights onto rocks to break them into smaller pieces. It then uses its extremely acidic stomach juice, which has a pH between 0.7 and 1, to dissolve the bones in less than a day. This adaptation allows it to access a food source that is largely ignored by other scavengers. This behavior, known as osteophagy, is a specialized survival strategy that helps the bearded vulture avoid competition for meat. The bird waits until other scavengers, like eagles or hyenas, have finished feeding on a carcass and then consumes the remaining bones. This unique feeding habit is made possible by the bird’s ability to drop bones on rocky surfaces to break them into smaller, manageable pieces. The vulture’s stomach acid is among the most powerful in the animal kingdom, allowing it to digest bones efficiently and extract nutrients that would otherwise be inaccessible. The bearded vulture had disappeared from the French Alps at the start of the 20th century. In 1993, a reintroduction program began in the Mercantour region, releasing 45 birds over the next two decades. Today, there are 98 territorial pairs of bearded vultures in the Alps, with five of those pairs located in the Mercantour National Park. To monitor the population, young birds are fitted with GPS and GSM tags, allowing researchers to track their movements and behavior. Since 2022, the National Park has been involved in this tagging program, and over thirty years, 25 chicks have been born in the area. Despite these conservation successes, the bearded vulture remains classified as Endangered by the International Union for Conservation of Nature (IUCN) at the European and Mediterranean level. The species represents both a triumph in conservation and a reminder of the delicate balance of ecosystems. While efforts have helped rebuild its population, continued protection and monitoring are essential to ensure its survival in the wild.
