Rondeau Provincial Park, sept 24, 2021.

Birds at the stream series.
Cardellina pusilla
Wilson’s Warblers tend to be brighter yellow in the West and paler yellow in the East. Pacific Coast populations have the brightest yellow, almost orange, foreheads and faces. Rocky Mountain and Alaskan birds also tend to be slightly larger than the Eastern and Pacific Coast populations.
