A small, compact parrot of lower and mid-montane forest and clearings. Green body, red vent, and a barred rump. Only males have a brown head. Similar to Modest Tiger-Parrot, but where they co-occur, Madarasz's Tiger-Parrot is usually at lower elevations. Males are very similar but Madarasz’s has larger diffuse, mustard spots on the back of the head. Female Madarasz's has a green head and strong barring on the back of the head. Call, a quiet, modulated high-low-middle whistle “wit-wu-wii”.
