The hypnotic, kinetic wind sculptures of Anthony Howe

I love stuff like this. I was just wondering if these things would be dangerous for birds. There is some kinetic sculpture near where I live, although it's nothing this elaborate and I'm sure birds can avoid them.
 
Good point Tom , never thought about it ...we have some birds down-under which are curious by nature that would flit around sculptures like that . I see that wind turbines kill a lot of birds .
