All regionsEdwards PlateauGeneralists

European Starling in Edwards Plateau has surged: up 858% on the route-weighted index since 1975.

+858%Since 1975TrendPercent change in the route-weighted abundance index between a smoothed baseline window and the most recent one. It tracks direction, not absolute population.Full methodology →

European Starling In Edwards Plateau Population Forecast

If the recent trend holds, European Starling in Edwards Plateau is projected to fall about 13% by 2030 — from 3.6 in 2025 to a central estimate of 3.1 (95% range 0.33–6.0). A 5-year backtest shows a typical error of ±63.3%, with 100% of held-out values landing inside the 95% band.
