House Wren

Came across this little Wren (a House Wren, I think), on one of the nesting boxes at the Calgary Zoo. I always think it's a neat thing when I see something wild that has made the Zoo its home. I've never seen a Wren before, close enough to photograph, so I was happy. I think I am so lucky that it takes only one small (insignificant to most people) thing to make my day : )
