Watch - And LISTEN - To A Flock of Hummingbirds As They Descend On A Bird Feeder

I've never seen this many hummingbirds in one place! You probably know that hummingbirds can beat their wings up to 80 times a second - these little guys are probably somewhere more in the 15 times a second range, though. But just listen to that amazing sound! I'd like to see this in MY backyard!
