Very welcome, I enjoyed the post. Ha haa, I've heard the hummingbird is the most aggressive bird, pound for pound, in the entire world. So they probably could power the entire city. And I'm quite sure this is correct, because I have a Masters of Studies from the Schteinn School of the Sophisticated Sciences (S.S.S.S.)
Their motto: Scimus scientiam
Which when translated means "We Know Knowledge"
