The western swamphen is a large rail native to tropical and subtropical wetlands across Europe, Africa, Asia, Australasia, and numerous islands. It occupies freshwater and brackish marshes, swamps, lagoons, lakes, river margins, estuaries, and wet agricultural areas. Adults are roughly chicken-sized, averaging 51 cm long. Their glossy indigo or purple plumage contrasts with a red bill and frontal shield, long orange-red legs, and conspicuous white undertail feathers. Females average about 850 g and males approximately 1,050 g. (Animal Diversity Web)
Swamphens browse marsh-grass and reed shoots and dig up plant bulbs, but also take arthropods, snails, fish, lizards, eggs, nestlings, and juvenile waterbirds. Their social breeding arrangements range from monogamous pairs to communal groups containing several adults and helpers. Males build multiple reed-and-sedge nests, including later brooding platforms near feeding areas. Each female lays three to six eggs, while a nest shared by several females may contain as many as twelve. Breeding adults cooperate in incubation and care of the chicks. (Animal Diversity Web)
