Editing Common moorhen (section)

==Distribution and habitat==
This is a common breeding and resident bird in marsh environments, rivers, well-vegetated lakes and even in city parks. Populations in areas where the waters freeze, such as eastern Europe, [[bird migration|migrate]] to more temperate climates. In China, common moorhen populations are largely resident south of the Yangtze River, whilst northern populations migrate in the winter; these populations show high genetic diversity.<ref>{{cite journal |author1= Ruan, L. |author2= Xu, W. | author3= Han, Y. | author4= Zhu, C. | author5= Guan, B. | author6= Xu, C. | author7= Goa, B. |author8= Zhao, D. | year=2018| title= Gene flow from multiple sources maintains high genetic diversity and stable population history of Common Moorhen ''Gallinula chloropus'' in China | journal=Ibis| volume=160| pages= 855–869| doi=10.1111/ibi.12579| issue=4}}</ref>
