All statesGeneralists

European Starling in Indiana has held roughly steady: up 0% on the route-weighted index since 1968.

+0%Since 1968TrendPercent 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 →
