The Monk Parakeet, also known as the Quaker Parrot, (Myiopsitta monachus) is a species of parrot, in most treatments the only member of the genus Myiopsitta. It originates from the temperate to subtropical areas of Argentina and the surrounding countries in South America.
The nominate subspecies of this parakeet is 29 cm long on average, with a 48 cm wingspan, and weighs 100 g. Females tend to be 10-20% smaller but can only be reliably sexed by DNA blood or feather testing. It has bright green upperparts. The forehead and breast are pale grey with darker scalloping and the rest of the underparts are very-light green to yellow.
The Monk Parakeet is the only parrot that builds a stick nest, in a tree or on a man-made structure, rather than using a hole in a tree.
Their diet is mainly seeds and fruit.In areas where they have been introduced, some fear that they will harm crops and native species.
This gregarious species often breeds colonially, building a single large nest with separate entrances for each pair. In the wild, the colonies can become quite large, with pairs occupying separate “apartments”
