Avian social systems during the breeding season can be classified into three major types:
territorial, cooperative or communal, and colonial. This classification is based on the degree …

The phenomenon of coloniality in birds has prompted several recent reviews on the
adaptive significances of colonial breeding (Lack, 1968; Panov, 1983a; Wittenberger and …

Colonial nesting in seabirds and other water birds is widespread, but it is relatively rare in
other birds (Lack, 1966). A colony is a breeding aggregation of birds characterized by many …

The word “colony” has several different definitions. Its use with respect to seabirds should
not be confused with the meaning when applied to human society, where, from Roman …

Most populations of coloflial birds exhibit extensive variation iu colony size. Field studies
over the last decade have shown that individual birds breeding in colonies of certain sizes …

The sociobiology of mixed species flocks is reviewed and used as a basis for evaluating the
adaptive significance of flocking. Virtually all data currently available deal with mixed flocks …

During the nonreproductive season, birds show a full spectrum of social organizations from
solitary birds aggressively defending feeding territories to flocking birds amicably sharing …

Stacey and Koenig discuss the phenomenon of cooperative breeding among birds, an

Australia has many cooperatively breeding species of birds. These tend to occur in eucalypt
and semi-arid woodlands rather than in rainforests or deserts. They tend to be insectivores …

Abstract Proponents of the Information Center hypothesis suggest that colonially breeding
birds learn the location of good feeding sites by following successful birds from a colony, that …
