Thanks for the response, everybody. Despite enthusiasm--here on COBirds, as well as over at Facebook and in my inbox--for Say phoebe, mountain bluebird, and lesser goldfinch, it is not any of those species. The mystery songster is in a bird family nobody has come close to yet. Anybody else want to chime in now? :-)
Ted Floyd Lafayette, Boulder County P.s. Up at Rabbit Mountain, northern Boulder County, this sunny solstice morn, June 20, Hannah Floyd and I saw a pair of *brown thrashers* bringing food to an apparent nest near the parking area. Didn't investigate the matter too closely, but I imagine that "apparent" nest is a real one. On Thursday, June 18, 2020 at 7:22:39 PM UTC-6, Ted Floyd wrote: > > Hey, folks.
