Yellow-throated Vireo Population Forecast

If the recent trend holds, Yellow-throated Vireo is projected to fall about 12% by 2030 — from 1.1 in 2025 to a central estimate of 0.94 (95% range 0.73–1.2). A 5-year backtest shows a typical error of ±21.3%, with 40% of held-out values landing inside the 95% band.
