A fascinatingly beautiful bird and its cousin can be found in Central and South America. Were talking about the Blue and Black-faced Dacnis. They are members of the tanager family. The Black-faced Dacnis lineata and the Blue Dacnis cayana are small passerine birds (12 cm long and weighing about 13 grams). More than half of all bird species, passerines are known as perching birds, and sometimes also as songbirds.
A word first about the Tanager family of birds. There are about 240 species of Tanagers living primarily in Central and South America. A few are migratory and get as far north as North America. They are all fairly brightly colored, although a few species are black and white. Many of the species live in the same areas but their different eating habits eliminate competition. For example, some of them eat insects off leaves; others catch them flying through the air. In temperate climates, the breeding season is March through June. In South America, it is September and October.
The genus, Dacnis, includes several species with common names identifying them primarily by color:
White-bellied Dacnis, Dacnis albiventris
Black-faced Dacnis, Dacnis...
