Hi, Dave & all.
It was just an oversight, of course, but maybe Dave didn't consult eBird for November 2013 warbler data?? Perish the thought. Anyhow, here's a nice description by Sean Walters of an orestera Orange-crowned Warbler, Larimer County, 4 November 2013:
So we can add Orange-crowned to the list.
A correction: Palm, not Pine, at Greenlee Preserve, Boulder County; and Pine, not Palm, from CU East Campus, Boulder County.
