selective focus photography of brown bird

This robin crashed on one of my window. He was convulsing, but we managed to get him in a box, with some blanket to keep him warm enough to survive. One hour later, he was able to move, then left his box 30 minutes later. He just stand on a chair for 10 or 15 more minutes, allowing me to take very close portrait of this small bird. Very impressive to see the complexity of feathers !
