Ruby-crowned Kinglet

Tiny gray bird, about the size of a kinglet. I was able to snap this picture, and then my batteries died on my camera. Tried to quickly change batteries, but It was too late, and it flew away. I feel like a could see a bit of red, but the picture I did get, has a stick covering the one spot I need to see. I want to call it a Ruby-crowned Kinglet, but not sure. Could also be a little larger than i'm remembering
