As I was stepping out just a few minutes ago to refill the hummingbird feeders, I noticed a huge flock of BB magpies circling and congregating along the Dakota Ridge below Mt Sanitas. Numbers were likely in the 150 range, similar to the flock of 174 I counted last year around this time, but not as conveniently organized for counting. One photo I took captured 103 individuals. Has anyone else seen similar flocks in Colorado recently?
Definitely an impressive sight!
