Habitat: The Grey Heron nests in all types of trees at a relatively short distance from suitable foraging areas. In polder areas, small polder woods and duck decoys seem to attract large numbers of herons. Park habitats are also very suitable, and many of the largest colonies are found in such areas. Smaller colonies are found in Canadian forests, marshy areas, alder thickets and even in the middle of pine forests. The blue heron is therefore not very choosy when it comes to breeding sites, and it can be said that the proximity of suitable foraging areas is the main requirement for the breeding biotope.
