Dacnis cayana is native to a broad range across South and Central America. It inhabits tropical and subtropical lowland forests, forest edges, plantations, and secondary growth areas, often venturing into gardens and city parks. The species is not globally threatened and is considered common in most of its range. It has adapted well to human-modified environments and can often be seen near human settlements where flowering trees and shrubs are present.

Males of this species are approximately 4.7 to 5 inches long, displaying a striking combination of turquoise-blue plumage with a black throat, back, and wings. Females differ considerably in coloration, with olive-green upperparts and bluish tones on the crown and nape, creating marked sexual dimorphism. These birds are active foragers, feeding on fruit, nectar, and insects, often seen hopping among foliage or flying short distances between trees. They have a fast, direct flight and exhibit a behavior of flicking their wings when perched. Breeding behavior includes the construction of small cup nests placed in low vegetation, where the female typically incubates the clutch of two eggs. Insect consumption is more frequent during the breeding season to meet protein needs.

There is no available evidence of commercial breeding or cultivation of Dacnis cayana for any agricultural or ornamental purposes in any country. It is listed as a species of least concern by global conservation organizations due to its wide distribution and stable population trends. survival in areas experiencing deforestation. Photographed in north-western Ecuador.
