All statesForest birds

Tufted Titmouse in Oklahoma has surged: up 76% on the route-weighted index since 1969.

+76%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 →
