The Green-rumped Parrotlet, is a small parrot species native to northeastern South America. It has been introduced to several locations, including Curaçao, Jamaica, Barbados, Trinidad and Tobago. The green-rumped parrotlet thrives in semi-open lowland areas and is sometimes found in urban parks, adapting to human-modified landscapes​​. Measuring approximately 4.7 inches in length and weighing between 0.71 to 0.99 ounces, these parrotlets display a vibrant green plumage, with males distinguished by purplish-blue and bright turquoise feathers on their wings, while females have more yellow-green on their heads. They possess zygodactyl feet, meaning they have two toes facing forward and two backward, a common trait in parrots. This physical adaptation aids in climbing and grasping food​​. The green-rumped parrotlets are gregarious, forming flocks of up to 100 birds outside the breeding season. They nest in hollow stumps, limbs, trunks, or arboreal termite mounds, and sometimes in palm frond bases or man-made structures. Females often attempt a second brood within the breeding season, which occurs for most of the year, depending on the location. Their clutch typically contains 5 or 6 eggs​​. The green-rumped parrotlet has been classified as 'Least Concern' by the IUCNs. They are also involved in the pet trade.
