Moonlit Migrants: Minnesota Braces for Massive Autumn Bird Flight
BirdCast forecasts about 321 million birds migrating at night across the continental US this Saturday night, with Minnesota in a broad migration band; most take off 30–45 minutes after sunset and peak 2–3 hours later. The counts are model-based estimates from radar data, not a literal tally. Minnesotans can help by turning off unnecessary outdoor lights to reduce bird collisions.
