AI recreated a lost birdsong from 1960s notes — wild sparrows started copying it

Per The Guardian, scientists used a computer to recreate a rufous-collared sparrow song lost from a Buenos Aires park since the 1960s, based on handwritten annotations. Within three months, a wild sparrow began copying parts of it.
The work points to a new conservation direction: when populations decline, fledglings lose chances to learn proper songs, hurting mate attraction and territory defense. With 4,000 of the world's 10,000 bird species being songbirds, AI-assisted recovery of lost dialects could improve endangered species' survival odds.
