Hi all, We had 2 Cassin's during this past winter in Lyons. The low estimated of 85 Cassin's Finches have been here over the last two snow storms this week. Most winters we will have just single digits even with heavy snows.
Bonus birds this week include a pair of Evening Grosbeaks and 4 Broad-tailed Hummingbirds. Stay healthy, Sue Riffe Lyons, CO On Thu, Apr 16, 2020 at 2:45 PM Richard Trinkner <[email protected]> wrote: > I'd be very interested in theories to explain this spring's dramatic > Cassin's Finch invasion of the lower elevations of the Front Range.
