Eurasian Collared-Dove Population Trend in Oregon

All statesGeneralists

Eurasian Collared-Dove in Oregon has surged: up 87× on the route-weighted index since 2008.

87×Since 2008TrendPercent 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 →
78Routes In StateSurvey routesHow many standard-protocol BBS routes contributed counts. More routes means a steadier, better-sampled index; very thin coverage is suppressed.Full methodology →
18YearsYears surveyedNumber of years with at least one standard-protocol run in this geography. A longer record makes the trend more reliable.Full methodology →
