Flocking Starlings

The last couple of mornings while walking along the Niagara Parkway I've been amazed by the enormous swarms of starlings forming intricate visual displays. The sound they make is also incredible. Unfortunately I didn't have my camera but I found this video that shows some starlings indulging in really remarkable behaviour.

Seeing the huge numbers of the birds it's hard to believe that North American starlings are all descended from 60 birds freed in Central Park by wealthy pharmacologist Eugene Schieffelin in the 1890s.
