Blue Dacnis (Dacnis cayana), also called the Turquoise Honeycreeper, is a small passerine bird, 5 inches long and weighs 0.45 oz.
The adult male is turquoise blue with black around the eyes, on the throat and back. The wings and tail are black, edged with turquoise. The female and immature Blue Dacnis are mainly green with a blue head, paler green underparts, and green-edged brown wings.
This bird is widespread in forests and other woodlands, including gardens and parks, in Central and South America from Nicaragua to Bolivia and northern Argentina.
The Blue Dacnis builds a bulky cup nest in a tree. The female usually lays a clutch of 2 to 3 grey-blotched whitish eggs. The female incubates the eggs, but is fed by the male.
These are social birds who eat mainly insects gleaned from foliage, flowers or bromeliads; as well as fruit.
