Blue Dacnis

A brilliantly colored tanager-like bird of tropical South America, male blue dacnis display vivid turquoise-blue plumage with a black back and throat, while females are green. Found in humid forest canopy and forest edges from Colombia and Venezuela south to Bolivia and Brazil. They inhabit the treetop foliage foraging for fruit, berries, and small insects, often joining mixed-species feeding flocks. They are important seed dispersers for small-fruited trees in Amazonian and Atlantic Forest ecosystems.

Green Sea Turtle
