You really must go see this video.  It’s fascinating:

It shows a flock of hundreds (thousands?) of European Starlings all trying to pack into one small Eastern Redcedar across the street from my house. The problem is there are far more birds then can fit in the tree and at some points it starts to get pulled down. You have to see this to believe it!

He’s absolutely correct.  The birds come back time and again and try landing on the same tree, only there are far too many birds for the tree to support.  It appears at times that the combined weight of the avian invasion will cause the tree to fall.

It’s absolutely mesmerizing.  Hitchcock would be proud.
