The grey heron is a solitary predator when hunting, but it becomes gregarious during the breeding season, forming colonies known as heronries. Patient and methodical, it remains still for long periods to ambush its prey. Its flight is slow, characterized by broad and regular wing beats.
Reproduction

The female lays between 3 and 5 pale blue-green eggs, which are incubated for about 25 days. Both parents participate in raising the young, which leave the nest after 7 to 8 weeks.
