摘要: Most current explanations of avian communal roosting focus on benefits derived at the roost itself and assume that the roost is the individual's base of operation. A very different view of communal roosting emerges when the birds are marked individually. A recent radiotelemetric study of communally roosting European starlings (Sturnus vulgaris) revealed that individuals are far more faithful to their diurnal activity centers (DAC's) than to their roosts (Morrison and Caccamise 1985). Studies of other communally roosting species have …
