Hello all,
Thanks for the various comments concerning the Brewer’s Sparrows on Guanella
Pass. We did not get recordings of the birds. Neither Michael or I have
recording equipment, and even if we had, it was a bit breezy yesterday and that
might have made it problematic anyway. The birds clearly seemed to be on
territory, and for anyone who has the equipment and the inclination, it could
be a good opportunity to record these high altitude Brewer’s Sparrows.

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.
