Subject: [cobirds] Brewer's Sparrow, Guanella Pass, Clear Creek County
This could be a Timberline which is a subspecies of the Brewer’s Sparrow. Did you get a recording?
Does anyone know the current status of research of the potential of separating the Timberline into a separate species? Any links would be appreciated.
