The video below is a phenomenon that I have seen many many times. A large flock of starlings swarming together and flying in formation at dusk before roosting for the night. Thankfully Neels Castillon, and Mathias Touzeris captured it while preparing for a commercial shoot.
This is a nice way to start your work week.
