Terminology of animal groups also varies among different taxonomic groups. Groups of sheep are termed herds, whilst groups of birds are referred to as colonies, or flocks. Most studies on group living focus strictly on groups comprising a single species. However, many mixed-species groups commonly occur in nature.
Group of black-capped chickadees feeding at a bird feeder. Bird species living in a flock may capture prey, likely injured, from an unsuccessful bird within its flock. [2] This behavior is known as the beater effect and is one of the benefits of birds foraging in a flock with other birds. [2]

Four apostlebirds (Struthidea cinerea) of a cooperative breeding group.Helpers at the nest is a term used in behavioural ecology and evolutionary biology to describe a social structure in which juveniles and sexually mature adolescents of either one or both sexes remain in association with their parents and help them raise subsequent broods or litters, instead of dispersing and beginning to ...
Flamingos or flamingoes [a] (/ f l ə ˈ m ɪ ŋ ɡ oʊ z /) are a type of wading bird in the family Phoenicopteridae, which is the only extant family in the order Phoenicopteriformes.

Swarm behaviour, or swarming, is a collective behaviour exhibited by entities, particularly animals, of similar size which aggregate together, perhaps milling about the same spot or perhaps moving en masse or migrating in some direction. It is a highly interdisciplinary topic. [1]
This section briefly reviews three main findings about the evolution of monogamy in animals. The amount of social monogamy in animals varies across taxa, with over 90% of birds engaging in social monogamy while only 3–9% of mammals are known to do the same. [6] [29] [30] This list is not complete.
Birds have one of the most complex respiratory systems of all animal groups. [78] Upon inhalation, 75% of the fresh air bypasses the lungs and flows directly into a posterior air sac which extends from the lungs and connects with air spaces in the bones and fills them with air. The other 25% of the air goes directly into the lungs.
