Song also differs between these subspecies, with Red-backed birds in
northern Arizona singing more complex songs on average (slower trills,
often 2-3 trills per song, often with 1-2 non-trill notes at start or end)
than our Gray-headed Juncos in Colorado. In general there is a gradual
transition

Peter et al,
The bird at Red Rocks was photographed by Steve Mlodinow, not me
I very much appreciate Steve Mlodinow, Doug Faulkner, and Christian Nunes
responding to my request for info on Red-backed Junco.

The other day, buried amid a mixed-subject post, I asked (so far unanswered) if
anyone on this listserv knows whether the so-called Red-backed Dark-eyed
Junco has occurred in Colorado and/or whether it has any history whatsoever of
occurring outside its normal range of Arizona to West Texas.
David,
The Colorado Bird Records Committee does not have any record for that
subspecies and I am unaware of any extralimital reports for other states
north of its range. My understanding is that Red-backed Junco does very
little (if any) seasonal movement in a way that would be considered
Doug Cobirds,
Since we're on the topic of Red-backed vs. Gray-headed Juncos, the field
mark I've been relying on is bill color: single color for Gray-headed,
bi-colored in the case of Red-backed. My question is whether this character
is diagnostic or not? The Junco David photographed at Red Rocks
