The decline in migratory bird populations poses risks to ecosystems and biodiversity. Birds that travel long distances, such as palearctic migrants, are particularly vulnerable, with some species experiencing over a 30% decline in the past three decades. Habitat loss, such as the 90% reduction in Lake Chad's surface area, deprives birds of critical resting and feeding grounds. Infrastructure collisions and ecological mismatches further exacerbate the issue, threatening species like the European roller and Egyptian vulture. These declines could disrupt ecological systems across continents, impacting both local and global biodiversity.
