My Year of Darwin 4/28/2014: Patagonia gigas, biggest of the smallest

"This second kind (Trochilus gigas) is a very large bird for the delicate family to which it belongs: when on the wing its appearance singular. Like others of the genus, it moves from place to place with a rapidity which may be compared to that of Syrphus among flies, and Sphinx among months; but whilst hovering over a flower, it flaps its wings with a very slow and powerful movement, totally different from that vibratory one common to most of the species" Charles Darwin - Voyage of the Beagle 

The Giant Hummingbird (Patagonia gigas) is a Chilean hummingbird and the largest hummingbird.
