Coloration varies significantly throughout wide distribution, with males ranging from black-and-crimson (most of mainland Asia) to black-and-yellow (southern Philippines) and black-and-orange (Java and Bali). Females are predominantly gray-and-yellow, but southern Philippine and western Indonesian birds are black-and-yellow. In all subspecies, note colored “blotches” on the wings (other minivets have cleaner wing patterns) and female’s yellow forehead. Gives high whistled “wheeep” notes, often when flying over the treetops.
