Podargus papuensis Quoy & Gaimard, 1830

Largest of genus, with long tail; coloration rather variable, and some birds much darker than others. Male´s upperparts generally appear greybrown, but in details have elaborate light and dark pattern; underparts generally light browngrey, with spots and short irregular bars of white, and variable blackish streaking; irides frequently bright red, but often orange, yellow or brown. Iris colour, when red, a useful distinction from congeners. Female much like male and similarly variable, although typically with more brown or rufous tone, especially on upperparts, and less contrasting light and dark markings; rarely, female (but apparently not male) occurs as “rufous morph”, almost entirely plain cinnamon. Juvenile coloration evidently very variable, from generally similar to adult to much paler, with underparts mainly white.
