Quaker Parrots (Myiopsitta monachus) are named for the scalloped ruff on their upper breasts resembling an old-fashioned Quaker neck cloth. They are also called the Monk parakeet for the pale feathers on top of their heads which looks like a monk's tonsure. Quaker parrots are the engineers of the bird world, and Quaker nests really are something to see - they are huge constructions, sometimes as big as a small car, often on manmade objects like telephone poles or streetlights. Inside, they are more like suites than nests. They have three separate areas: an incubation room, plus a sort of living room and front porch. It originates from the temperate to subtropical areas of Argentina and the surrounding countries in South America. Self-sustaining feral populations occur in many places, mainly in North America and Europe.
