Hummingbirds in Colorado

I did not grow up around hummingbirds. Every time I see them, I'm fascinated. They amaze me with their acrobatics. Sometimes flying so fast that they only appear as a blur. I love that they can flap their wings so fast and actually hover quite still. Sometimes they will give you a very close fly-by, always completely in control. I wish I lived a bit closer to the mountains so that I could watch these guys every year as they pass through on their migratory route.
