Tracking the Ortolan with AI - AI joins the fight to save Bavaria's last ortolan buntings from extinction

The ortolan bunting, a small songbird once widespread across Europe, now faces extinction in Bavaria. Conservationists are turning to artificial intelligence for the first time to track its dwindling numbers. The last remaining population clings to survival in a narrow stretch between Würzburg and Schweinfurt in Lower Franconia.

Over the past five years, surveys by the Bavarian Ornithologists' Association recorded just 150 to 200 ortolan buntings in the region. Data shows a sharp decline of 20 to 30 percent, driven by habitat loss and intensive farming. This isolated group is the only one left in Bavaria, with the nearest neighbours 400 kilometres away—singing in a different dialect.

This year, a bioacoustic monitoring project will analyse the birds' songs, which act like acoustic fingerprints for each individual. By studying call variations, researchers hope to uncover survival rates during migration, how far they settle from their birthplace, and even details about pair bonding and nesting habits.

Conservation efforts extend beyond technology. The LBV (Bavarian Society for the Protection of Birds) is working with local farmers to adopt bird-friendly land management. They are also planting trees to create song posts, as male ortolans prefer high perches to sing from. Females and juveniles, meanwhile, stay hidden in the undergrowth.

The ortolan's call is distinctive, with a Franconian twist in Bavaria. But without intervention, this regional dialect—and the birds themselves—could soon disappear for good.

The project combines AI analysis with practical conservation to slow the ortolan bunting's decline. If successful, it could provide a model for saving other threatened species. For now, the focus remains on the fragile population between Würzburg and Schweinfurt—where every song counts.
