All statesGeneralists

Eurasian Collared-Dove in Washington has surged: up 35× on the route-weighted index since 2009.

35×Since 2009TrendPercent 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 →
