Elf Owl
381. Micropallas whitneyi. 6 inches.
This odd little bird is the smallest of the family found in America. In plumage it may be described as being very like a small Screech Owl, without the ear tufts, only with the pattern of the markings much finer. They are quite abundant in central Mexico and in southern Arizona, where they build their nests in deserted Woodpecker holes, or perhaps more frequently in the giant cactus. It differs from the preceding in being a bird of the night, rarely flying in daylight. They feed almost exclusively upon insects, and rarely a mole or field mouse. They lay from three to five white eggs, having a slight gloss (1.02 ×.90).
