Noisy miners are gregarious and territorial; they forage, bathe, roost, breed and defend territory communally, forming colonies that can contain several hundred birds. Each bird has an 'activity space' and birds with overlapping activity spaces form associations called 'coteries', the most stable units within the colony. The birds also form temporary flocks called 'coalitions' for specific activities such as mobbing a predator.
