Great blue herons show territoriality depending on sex, age, and season. Males protect their territory all year round, and females during the nesting period.

The gray and blue color of the plumage makes it invisible against the sky and water.
In flight, birds bend their necks in the shape of the Latin letter S, and their legs are kept elongated along the body. No such bending is observed during takeoff or flights for short distances. The flying heron slowly and deeply swings its wings, announcing its approach with screams. The average flight speed is about 32-48 km/h.
Frying takes place in shallow water at depths of up to 50 cm or in wet ground. On dry soils, it is very rare to find food. During hunting the hunter stands still for a long time until the potential victims stop considering her dangerous and approach the minimum distance.
In streams or slowly flowing rivers, it gradually moves forward against the current, while in standing water it drives the fish with open wings or kicks.
The great blue heron is looking for food Mining grabs with the lightning movement of its beak. Sometimes the bird puts its head in the water and looks for prey at the bottom. It can dive for life in deep waters, but this behavior is not typical for this species.

Great blue throats nest in colonies, much less in pairs. They often neighbor with White Herons (Ardea alba), Eared Cormorants (Phalacrocorax auritus), and Common Quakers (Nyctocorax nyctocorax). Most often colonies are located on islands or marshes inaccessible to predators, surrounded by tall trees at a distance of 2-12 km from inhabited areas and with abundant nest-building material.
Their location varies periodically and depends on the stability of green spaces. They are surrounded by guanos, which are highly phytotoxic and kill plants.

The gentlemen present their chosen ones with twigs and blades, while the ladies greet them with stretched necks and raised beaks while performing numerous curtsies.
Both partners try to fluff up their feathers and make short intermittent sounds, accompanying the exchange of courtesies with a dance in a circle. Then they tingle each other’s feathers and start mating, which lasts 12-15 seconds.
In the northern part of the range, females lay eggs from March to May, and in the southern part from November to April. There are 3-7 light greenish-blue eggs of about 62×63 mm in size and 65-75 g in weight. Eggs are laid with a period of 2-3 days.
In case of death of the clutch, the female may lay it again. Close human presence adversely affects the hatching of chicks. Scared birds usually leave the nest not only with laid eggs but also with hatched chicks.
The female incubates the clutch at night and is replaced by a male during the day.
The incubation lasts 25-29 days. The chicks hatch at intervals of several days. First-borns grow more rapidly and oppress their younger brothers, taking away their food. Both parents feed them, burping food right into their beaks during the first 10 days. Then the babies themselves climb into their parents’ beaks. As they grow older, their parents simply throw fish change into their nest.
