Giant pitta Hydrornis caeruleus

Extremely elusive and rarely-seen ground-dweller; listen instead for its haunting whistle. If seen, overall size and chunkiness alone should be sufficient to distinguish this species from other pittas. Male has bright blue wings and a grayish head with a thin black line curving downwards from behind the eye. Female is browner overall, with a blue rump and warm rufous-brown wings. Rare in lowland and foothill forests, particularly in swampy or riparian areas.
