| Gallinula tenebrosa Gould, 1846 |
The Dusky Moorhen (Gallinula tenebrosa) is a bird in the rail family which occurs in Australia, New Guinea and Indonesia.
The New Guinea birds are smaller, at 25-32cm in length, than the Australian race (35-40 cm, 55-65 cm wingspan). In Indonesia, this species is losing ground to the closely related Common Moorhen on those islands where both birds occur.
The adult Dusky Moorhen is mainly dark grey-black, with a browner tinge to the upper parts. It has a red frontal shield and yellow-tipped red bill like its Eurasian relative, but lacks the white flank line shown by Common Moorhen, and has orange-yellow rather than yellow legs.
Sexes are similar, but young birds have mid-brown plumage. This is a noisy species with a loud kruk call.
Dusky Moorhen is found in wetland habitats, with a preference for freshwater marshes. It will forage on rubbish tips, and is generally omnivorous, taking a wide variety of plant and animal food.
This species builds a bulky nest at the water's edge, and lays 5-18 whitish eggs. It is territorial when breeding, but otherwise gregarious.
