Welcome to the 2021 Joe Roller Memorial Green Big Year Blog! The Colorado birding community lost one of its pillars when Joe Roller passed away in November 2020. Joe was a fountain of birding lore and loved people as much as birds. Many considered him a beloved friend. To honor Joe's legacy, I've partnered with Colorado Field Ornithologists (CFO) and created the Joe Roller Memorial Grant to support bird research in Colorado. The grant will be initially funded by pledges raised through my 2021 Green Big Year, a green (carbon-free) birding initiative. I will be walking or riding my bike from my house in Littleton, Colorado to see as many species as possible in 2021. My 2020 green list is currently 244 species, but I am aiming for at least 250 bird species in 2021! I'll update this blog with adventures, birds, and photos throughout the year. We are taking per-species pledges and flat tax-deductible donations towards the Grant online at https://Cobirds.org/CFO/Grants . (Scr
