Accurate extent of occurrence (EOO) estimates are essential for reliable conservation assessments. Recent studies suggest that current EOO maps often significantly overestimate range sizes of birds, particularly for narrow-ranging, threatened and ecological specialist species. Such species may therefore be at danger of being falsely overlooked by(More)
