I know, I know, european starlings are an invasive species...

Last night, right around dusk the trees to the west of my house started to fill up with starlings. They sat in the tops of the trees squawking. I started to go for my rifle, but then about five or six large flocks of starlings flew in and perched on some power lines to the south. And then several other small groups flew in and the birds perched in the trees and on the power lines were drawn into the air like they were magnetized. There must have been 1000 starlings overhead as they swam overhead in a huge mass of flowing, beating wings. My daughter is almost four years old and we sat on the porch together, with her in my lap, and watched the giant swarm move together and around and broke off and came back together. My daughter oohed and awed as the starlings would swarm overhead. It was pretty amazing to watch. The sheer amount of birds was incredible, but the way they were able to move in such concert was breathtaking. 


That being said, if any of them would have landed close enough, they'd caught a .22 pellet in the brainpan.
 
Starlings are getting quite 'rare' here in the UK, I can remember when they were a general nuisance (mostly down to roosting in large numbers = bird cr@p everywhere). Their population is now restricted to a few areas with large reed marshes.

Quite a beautiful bird really and they have been shown to be highly intelligent.

Another 'problem' bird in the US is the Sparrow apparently, exactly the same has happened with their population here - whilst not rare they are seen & heard much less frequently these days (we Brits tend to think of them as "cheeky chappies").
