Western Swamphen
Porphyrio porphyrio
Distinctive large waterbird, much larger than a moorhen. Deep purplish-blue overall with a very stout red bill, reddish legs, and a white undertail patch. Juvenile duller overall, mostly grayish. Native to the western Mediterranean, but has turned up in northern Europe as well. Inhabits freshwater and brackish marshes, clambering among tall reeds and rushes; also feeds at edges, even out in adjacent wet fields. Very vocal, giving a wide variety of grunting and squealing calls. Formerly part of the species known as Purple Swamphen.

行为
The species makes loud, quick, bleating and hooting calls which are hardly bird-like in tone. It is particularly noisy during the breeding season. Despite being clumsy in flight, it can fly long distances and is a good swimmer, especially for a bird without webbed feet.<p>Western swamphens are generally seasonal breeders, correlating with peak rainfall in many places, or summer in more temperate climes. The purple swamphen breeds in warm reed beds. The pattern of social behaviour tends to be monogamy.<p>Pairs nest in a large pad of interwoven reed flags, etc., on a mass of floating debris or amongst matted reeds slightly above water level in swamps, clumps of rushes in paddocks or long unkempt grass. Each bird can lay 3–6 speckled eggs, pale yellowish stone to reddish buff, blotched and spotted with reddish brown. The incubation period is 23–27 days, and is performed by both sexes. The precocious chicks are feathered with downy black feathers and able to leave the nest soon after hatching, but will often remain in the nest for a few days. Young chicks are fed by their parents (and group members) for between 10–14 days, after which they begin to feed themselves.<p>The western swamphen prefers wet areas with high rainfall, swamps, lake edges and damp pastures. The birds often live in pairs and larger communities. It clambers through the reeds, eating the tender shoots and vegetable-like matter. They have been known to eat eggs, ducklings, small fish and invertebrates such as snails. They have even been known to attack large eels; however, there is no consensus amongst ornithologists if they actually eat eel. They will often use one foot to bring food to their mouth rather than eat it on the ground. Where they are not persecuted they can become tame and be readily seen in towns and cities.

Bush Thick-knee
Burhinus grallarius
Distinctive large shorebird with long legs, enormous yellow eye, heavily streaked underparts. During the day stands or sits under small trees/shrubs, often in small groups. When disturbed will lie down and flatten neck to the ground. At night becomes active and wanders around calling its wonderful eerie wailing cry. In cities like Darwin, Cairns, Brisbane it is relatively common in parks, open grounds, camping grounds. More common across northern Australia.
Little Wood-Rail
Aramides mangle
The smallest wood-rail with a white throat and a rusty breast and belly. Note the green bill with a red base. Found in mangroves, swamps, and lagoons along the coast, but also migrates to interior dry-land areas to breed. Similar to Slaty-breasted Wood-Rail, which only occurs in woodlands and has a gray (not rusty) breast. Told from Gray-cowled Wood-Rail by its white throat rather than the gray throat seen on Gray-cowled Wood-Rail.
Black-winged Lory
Trichoglossus cyanogenius
A large, long-tailed lory of forest and secondary growth on the Bay Islands. Mainly red plumage, with violet mask, and black shoulder, flanks and upper tail. In flight, mainly red from below. Seen in pairs or small flocks. In range, the only other similar-sized red parrots are Black-capped Lory, which has black and yellow in the wing and a shorter, rounded tail; and Rainbow Lorikeet which has green wings and tail. Call, a shrill, ringing “kriik!” or double “kriik kruk!” with the second note lower.
