Nicolle, my take on this question is that within the last 15 years, Black-chinned Hummingbird has extended its normal breeding range on the east side of the Rockies from El Paso County northward to Bellvue in Larimer County, and always near the edge of the foothills. I suspect they have extended even farther north (into Wyoming??).
I haven’t checked any formal databases, just my impression from personal experiences and following the listserve discussions. E-bird would be a good resource for this question.

Are they not considered common? I have had one or two (last weekend I had two) at my feeders every year since 2003 (Chatfield Resevoir area). As always, I appreciate your comments and insight.
