The Research Progress of Avian Communal Nocturnal Roosting Function Based on Spatial and Social Organization
Communal nocturnal roosting involves individuals of the same or different species congregating at a shared roost and its surrounding habitat.Communal nocturnal roosting behaviour is widespread among birds,where individuals occupy dispersed positions within roosts to achieve functions such as an increase in foraging efficiency,a decrease in predation risk and a reduction in thermoregulation demands.However,different individual's position in the roost will influence the exact individual benefit derived from roosting,and the social cognitive abilities concerning avian social relations and social status will affect the individual's position choice.The paper summarizes the relevant hypothesis and theories,research methods and progress of communal nocturnal roosting function based on spatial and social organization in birds,and discusses the existing problems and future research directions.
