A Murder of Crows! Fun Video Captures the Daily Movement of our Downtown Flock
Although it was shot three years ago, this video titled Murder of Crows - January 6, 2014 - MPLS, MN by Matt Koskinen of Koskinen Video Productions could have been this January. I witness these swarms nightly on the way home from work (fascinating, but a little spooky!).
I wasn't aware that a flock of crows is known as a "murder". Maybe spending some time hanging out with ornithologists is in order. :)
