A murmuration of starlings

Video found at the Presurfer; venereal term for a large group of starlings found here.

I've seen this type of mass flocking before, but this particular video is quite impressive. It lasts a minute-and-a-half and is well worth clicking.

If you see somethink like this near your home, or there is a starling roost on trees near you, you need to read about histoplasmosis.
