How fast can a hummingbird fly?

I'm watching the hummingbirds zip around my hummingbird feeders and I'm wondering what bird is the fastest?

Ruby-throated hummingbirds can fly up to 27 mph and if they catch a good wind they can move up to 60 mph.

But the fastest living creature is believed to be the Peregrine Falcon Falco peregrinus, reaching speeds of at least 124 mph and possibly as much as 168 mph when swooping from great heights.
