Summary

PBS NewsHour’s Horizons examines a new study revealing that over half of global migratory bird populations are declining due to habitat loss, climate change, and human threats. Ornithologist Peter Pyle discusses the ecological importance of birds and highlights historical conservation successes, such as the recovery of species after banning DDT. He urges individuals to keep cats indoors, plant native gardens, and reduce lawn areas to support biodiversity. The episode concludes by noting that birdwatching can enhance cognitive health and neuroplasticity in older adults.
