Eurasian Collared-Dove Population Forecast

If the recent trend holds, Eurasian Collared-Dove is projected to rise about 20% by 2030 — from 2.7 in 2025 to a central estimate of 3.3 (95% range 2.5–4.0). A 5-year backtest shows a typical error of ±14.1%, with 100% of held-out values landing inside the 95% band.
