I came across this truly unimaginable video posted on Facebook today, showing a real birding spectacle what not every day one can witness. Steve Gifford’s caption tells everything.
This is just a 60-second clip of a flock of grackles and blackbirds that took 20 minutes to pass by.
This short video was taken at the Patoka River National Wildlife Refuge near Oakland City, Indiana.
When I watched this video I tried to imagine the what that famous Passenger Pigeon migration could have been. A single giant flock was thought to be 1 mi (1.5 km) wide and 300 mi (500 km) long. The flock was passing over an area in southern Ontario in 1866 what took 14 hours, and held in excess of 3.5 billion birds! I have no idea how many birds flew over the Patoka Rover WR in this video but this was just a fraction of the spectacle.
Video possibly doesn’t appear under Safari but works fine with Chrome!
