Known locally in Panama as 'sangre de toro' ('bull’s blood') for the male’s deep crimson hue. It adapts well to edges and gardens and has been introduced to French Polynesia, where it is now established. Males and females look quite different, with females much duller and brownish. These tanagers are frequent visitors to fruiting trees and feeders.
