The times of dispersal and assembly of a roost of starlings (Sturnus vulgaris) near Crewe showed an earlier departure before sunrise and a later assembly after sunset from late Nov. to Jan., when the days were shorter, than later in the spring. The duration of the communal flying before descent into the roost and the period of assembly was also shorter during midwinter. Definite flight lines were regularly used but the number of birds using each line varied from time to time as the birds changed their feeding ground. Preliminary as-sembly before arriving at the roost often occurred at remote poits Birds going to distant feeding areas dispersed first and returned late during assembly thus permitting a nearly equivalent time at their feeding grounds. Starlings occupied one-part of the wood and other spp. of birds used the remainder without any sign of hostility.
