Original: 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.
Simplified: The parakeet is average 29 cm long, with a 48 cm wingspan, and weighs 100 g. Females tend to be 10-20% smaller, but it is hard to tell the sex apart, unless they test the feather or see the DNAs in the blood.
