Re: [cobirds] Brewer's Sparrow, Guanella Pass, Clear Creek County

Susan et al.,

Last I knew, there was no evidence that the Brewer's Sparrows occasionally found above treeline in Colorado belong to the "Timberline" subspecies. All available evidence suggested that these were typical Brewer's Sparrows that sometimes nest at high elevations (possibly for a second nesting attempt). As far as I am aware, the southern limit of breeding "Timberline" Brewer's Sparrows is in the Glacier National Park area of northern Montana.

That said, it's always a good idea to get a recording of interesting birds like this!

This could be a Timberline which is a subspecies of the Brewer's Sparrow.  Did you get a recording?
AND
Does anyone know the current status of research of the potential of separating the Timberline into a separate species?  Any links would be appreciated.
