I love humming birds! You caught a great shot of a very pretty one. I have humming birds living in my bottle brush bush in the back. I alwyas see them, but never capture them with the camera. Here is the only shot I have of a humming bird. The top is the whole shot, the bottom is the same shot, but cropped to show the little bugger. Every time I go out to take pics of them, they buzz (or hum) around me but never stay in sight for long. My camer has a big delayed focus so it's almost impossible. You did a GREAT job! And I agree....your window is WAY too clean! ;)
