From an Upland Sandpiper at 2:20 a.m. to Canada Goose at 9:56 p.m. (interestingly, both reported by Nathan Pieplow from the CU Boulder Campus—and I should note that Nathan also recorded species from Leadville and Silverthorne during the “regular” part of the day), eBird currently shows a pretty impressive 276 species reported in Colorado yesterday. Since some additional “flagged” species would not appear in the total, I suspect that birders in Colorado pushed 300 species collectively yesterday.
I hope all of you got out to see some of them.
