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

Just a quick reminder that the majority of birders DO own recording equipment -- a cell phone! There are plenty of free apps that will turn your cell phone into an audio recorder. It doesn't matter a whole lot which app you use, since the quality of the recording is generally determined by the quality of the microphone in your phone. Those microphones are designed for the human voice at 2 inches, not a bird at 200 yards, but a bad audio recording of a bird is better than no recording at all!

I own a couple different sets of recording equipment, but the phone is the one that's on me at all times. It came in super handy a couple weeks ago when I found a White-eyed Vireo singing while I was walking the dogs. And I pull it out every time I hear a Red Crossbill fly over, so I can document the call type. It's a good habit to get into.

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.
