All regionsNorthern RockiesGeneralists

Eurasian Collared-Dove in Northern Rockies has surged: up 21× on the route-weighted index since 2007.

21×Since 2007TrendPercent 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 →
