The Grey Heron (Ardea cinerea) is native to the Europe, Asia, and parts of Africa. Its geographical distribution extends across these continents, with prominent populations found in countries such as the United Kingdom, France, Germany, China, Japan, India, and the eastern and southern parts of Africa.

Grey Herons typically inhabit wetlands, including rivers, lakes, marshes, and coastal regions. They are highly adaptable and can also be found in urban and agricultural areas with adequate water bodies. The climate in their habitats ranges from temperate to tropical, depending on the region.

Grey Herons are often found at the top of the food chain in these environments, feeding primarily on fish, amphibians, small mammals, and occasionally birds. Their long legs and necks allow them to wade into deeper waters to hunt, and they use their sharp beaks to catch prey. The heron's presence in both freshwater and brackish ecosystems demonstrates its ecological adaptability.
