If you hang out in the BioTrek ethnobotany garden long enough, you'll probably see these guys flocking from one flower to another. They are just too hyper! The day was cool enough to be out in the garden, I picked a spot, camped and waited. I'm glad to say that I didn't wait in vain that day.
These tiny guys are among the smallest of birds (7 to 13cm) only, and they can fly backwards! Flying speed approximately 54 km/h and they're in a lot of poems. One of them is written by Emily Dickinson:
The Hummingbird
A route of evanescence
With a revolving wheel;
A resonance of emerald,
A rush of cochineal;
And every blossom on the bush
Adjusts its tumbled head,--
The mail from Tunis, probably,
An easy morning’s ride.
