Here is a nice pic by Gary Witt of our Black-throated Sparrow on today's DFO field trip to Gilpin County.
I looked at fall (Aug-Nov) occurrences in Colorado in eBird and saw just 5 prior fall season records from the Front Range region (Boulder 3, Jefferson 1, Douglas 1) - all down out of the mountains. The bird today at Central City Reservoir is the only fall report in eBird from the mountains in all of northern Colorado.

This is the second time a DFO field trip has come up with a first county record in Gilpin County this year (the other was Black-and-white Warbler 6/3). Maybe we need more visits. :-)
