Small tanager-like bird found in the subtropical zone of the Andes from Venezuela to Bolivia. Sharp pointed bill. Male is dark blackish overall with cobalt highlights shoulder and rump, and a blue (south) or white (north) crown. Female very different: olive above with gray head and chest and yellow belly. Her blue crown can be difficult to see. Even in poor light, easily picked out of a mixed-species flock by its frequent tail pumping.
