📆 Saturday, September 20th, at Marquee 1, we’ll be joined by Prof. @peralstrom.bsky.social, ornithologist and former core member of the AviList team. 📔 He will present the new unified global bird taxonomy known as AviList, which aims to be the definitive tool for ornithological classification.

In India’s Assam, women have joined forces to save the resident greater adjutant stork which was long considered a “dirty, smelly bird” that villagers would attack. The population rise linked to these efforts has caused them to be reclassified by the IUCN from endangered to near threatened.
