Volume 3, Plate XXV / Ornithology (Birds)
Topaz-Throated Humming-Bird
Trochilus pella
A curious variety of the topaz-throated species in an imperfect state of albino, in which pure white feathers contrast beautifully with the gorgeous plumage of the other parts, the latter losing nothing of their brilliancy. It proves contrary to a notion that white or pale varieties do not occur in birds of shining metallic lustre, much as such variation appears in the common Starling, Pheasant, and Peacock.
