A lot of European Starling come to my garden for food, I took several shots to one of them, and when I was checking them in my computer I found this one, I never noticed the feathers like this, it looks like in a less of a second it did a kind of movement that made its feathers looks this way. I was looking for the name of this bird on the internet and I found an interesting information on how they came to America : http://www.aspensongwildbirdfood.com/bird-profiles/european-starling
