[cobirds] Massive murder of crows, Denver 1/15

Not nearly as exciting as a Rufous-backed Robin (or perhaps the Civic Center Brant either), but over the last several weeks a mass gathering of American Crows has been occurring in downtown Denver late each afternoon (on the Auraria Campus on 1/15) and taking flight in a long stream winding through the buildings, destination: the US Bank building (I believe).  If you happen to be downtown for dinner, show, or a concert, it might be worth getting there a bit early for a stroll by the campus, or a glance upward around 5:00 pm to enjoy the spectacle.  On 1/15, I arrived at Auraria around 4:45 and watched until dark at about 5:30, counting 2,925 crows.
