Красногрудая трёхперстка Turnix pyrrhothorax

Small, dark, secretive buttonquail with pale eye, found in dense grassland habitats, where most commonly observed exploding from cover and flying rapidly away. In flight, note the fairly uniformly dark upperparts, with less contrast between flight feathers and coverts than in most other buttonquail. Adult female has rich rusty-orange chest; male paler, with white chin. Call is a repeated "oom-oom-oom-oom," with end of each note ascending in pitch.
