Yellow-billed Cuckoo In Edwards Plateau

All regionsEdwards PlateauGeneralists

Yellow-billed Cuckoo in Edwards Plateau has fallen sharply: down 55% on the route-weighted index since 1969.

-55%Since 1969TrendPercent 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 →

Forecast

If the recent trend holds, Yellow-billed Cuckoo in Edwards Plateau is projected to fall about 47% by 2029 — from 8.0 in 2024 to a central estimate of 4.2 (95% range 0.00–10.0). A 5-year backtest shows a typical error of ±42.2%, with 100% of held-out values landing inside the 95% band.
