The common moorhen (Gallinula chloropus) is a medium sized water bird belonging to the crake and rail family, Rallidae. The moorhen is distributed in Europe, Africa, Asia, Indian subcontinent, Southeast Asia, Philippines and Indonesia. Except for polar regions and tropical rain forests, it is found in most of the wetlands, marshes and water bodies with thick vegetation. There are five recognized subspecies of the common moorhen.

Habitat
These moorhen species inhabit reedbeds, freshwater wetlands, marshes, swamps, flooded pasture, slow-flowing rivers, flooded meadows, flood-plains, irrigated lands and flooded agricultural fields. They appear to avoid saline habitats.Diet and feeding habits
These moorhen species are omnivorous and feed on plant matter like algae, moss, the vegetative parts of reeds, aquatic plants, flowers, seeds, grass, shoots, berries, fruits and cereal crops. They also feed on small fish, invertebrates, aquatic insects, terrestrial insects, worms and mollusks.Breeding
These moorhen species usually breed during rainy season, the exact timing varying with respect to local geographical conditions. The moorhen nest is cup-like structure constructed from twigs and marsh vegetation. It may be a floating structure or placed on marsh vegetation or even on bushes and trees up to eight meters from ground. The clutch may contains up to 8 eggs. Both the parent birds incubate and feed the young ones.Distribution
The moorhen nominate subspecies G. c. chloropus is distributed in Europe, North Africa, Indian subcontinent, East Asia and Southeast Asia. The subspecies G. c. meridionalis is distributed in sub-Saharan Africa. The subspecies G. c. pyrrhorrhoa is distributed in Madagascar, Réunion Island, Mauritius and Comoro Islands. The subspecies G. c. orientalis is distributed in Andaman Islands (India) Peninsular Malaysia, Indonesia (Greater Sundas and Lesser Sundas), Philippines and Palau Island. The subspecies G. c. guami is distributed in Northern Mariana Islands (United States insular areas) and Guam (U.S. island territory).Movement and migration Patterns
These moorhen populations are mostly resident. The northern populations may make partial migratory movements to southern parts to avoid freezing conditions in the winter. These moorhen species move locally within their range for foraging and breeding.Conservation status and concerns
These moorhen species global population is estimated to be around 2,900,000 to 6,200,000 individual birds. The overall population trend is considered to be stable. As it has a very large range, it is considered not Vulnerable. The loss of wetlands and marshes due to human activities is the main threat to the survival of these moorhen species.The IUCN (International Union for Conservation of Nature) has categorized and evaluated these moorhen species and has listed them as of "Least Concern".
