Check out this is a video of a half a million birds swarming over Sacramento California. After watching this I thought about a B movie I watched back in the late 70s called "Swarm". It was about a bunch of Americanized bees that wrecked havoc in Houston. Well the way these birds are flying over the city of Sacrament reminded me of the way the bees swarmed over Houston in the move the swarm. Check out the video of the Birds over Sacrament here
