The blue dacnis or turquoise honeycreeper is a small passerine bird. This member of the tanager family is found from Nicaragua to Panama, on Trinidad, and in South America south to Bolivia and northern Argentina. It is widespread and often common, especially in parts of its South American range.

The Blue Dacnis is an active little bird of the rainforest canopy, foraging for insects and fruits most often in the highest treetops. It can also be found along woodland edges and clearings with trees, and a variety of other habitats throughout its range. Blue Dacnis are social birds, and pairs tend to associate with mixed feeding flocks – up to 12 individuals may be present in a flock! Blue Dacnis are not overly vocal; their call is a high-pitched, thin “tsit” and their song isn’t much more than that.
