Communal roosting is an animal behavior where a group of individuals, typically of the same species, congregate in an area for a few hours based on an external signal and will return to the same site with the reappearance of the signal.

Rooks are highly gregarious birds and are generally seen in flocks of various sizes. Males and females pair-bond for life and pairs stay together within flocks. In the evening, the birds often congregate at their rookery before moving off to their chosen communal roosting site.

Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses ; wetland species such as herons ; and a few passerines such as weaverbirds , certain blackbirds , and some swallows .
A rookery is a colony breeding rooks, and more broadly a colony of several types of breeding animals, generally gregarious [1] birds. [2] Coming from the nesting habits of rooks, the term is used for corvids and the breeding grounds [3] of colony-forming seabirds, marine mammals (true seals or sea lions), and even some turtles.
