How much space do great blue herons need?

Great blue herons typically require a nesting territory of about 1 to 4 acres, depending on the availability of food and habitat quality. They prefer to nest in colonies near water sources, such as lakes, rivers, or marshes, where they can access fish and other prey. Adequate space is essential for avoiding competition and ensuring that they have enough resources for feeding and breeding. Additionally, their foraging range can extend up to several miles from their nesting sites.
