Psittatus solstitialis, commonly known as the Sun Conure, is a vibrantly colored parrot native to northeastern South America. Known for its bright yellow plumage with orange-red accents, it inhabits savannas and forests. Social and intelligent, it forms large flocks and communicates with loud, distinctive calls. Aratinga nenday, or the Nanday Parakeet, is recognized by its green body and black head. Found in South American wetlands, it thrives in noisy flocks, adept at mimicking sounds and adapting to urban environments.

Psittacus solstitialis, commonly known as the Sun Parakeet or Sun Conure, is native to northeastern South America, primarily found in the regions of Guyana, southern Suriname, southern French Guiana, and northern Brazil. Aratinga nenday, commonly known as the Nanday Parakeet or Black-hooded Parakeet, is native to central South America, including regions of southern Brazil, Bolivia, Paraguay, and northern Argentina.

The Sun Parakeet inhabits tropical and subtropical regions, favoring savannas, dry forests, and open woodlands with a preference for areas near water sources. They thrive in regions with a warm climate and are often found in lowland forests up to an elevation of 1,200 meters. The Nanday Parakeet prefers similar environments, occupying open woodlands, forest edges, savannas, and palm groves. It is also adaptable to urban areas, often seen in parks and gardens.

Both species occupy the ecological niche of seed and fruit eaters, playing a role in seed dispersal within their environments. The Sun Parakeet is known for its social behavior, often forming flocks that enhance their foraging efficiency and protection from predators. The Nanday Parakeet exhibits similar social dynamics and adaptability, which allows it to exploit a variety of feeding opportunities, including agricultural areas, which sometimes leads to conflicts with farmers.
