The great egret (Ardea alba), also known as the common egret, large egret, great white egret, or great white heron, is a large, widely distributed egret. The four subspecies are found in Asia, Africa, the Americas, and southern Europe. Recently, it has also been spreading to more northern areas of Europe. Distributed across most of the tropical and warmer temperate regions of the world, it builds tree nests in colonies close to water.
The great egret is generally a very successful species with a large and expanding range, occurring worldwide in temperate and tropical habitats. It is ubiquitous across the Sun Belt of the United States and in the Neotropics.
In the Nordic countries, it was historically a rare visitor. The first breeding was observed in Sweden in 2012 and in Denmark in 2014. In 2018, a pair of great egrets nested in Finland for the first time, raising four young in a grey heron colony in Porvoo.
