Abstract:Greenfinches were observed arriving at and departing from a communal roost on more than 50 occasions each. They settled at the roost earlier than expected for the season at low, and later than expected at high light intensities. Departure time was negatively correlated with the number of birds in the roost. Light intensity when late birds departed was positively correlated with the number of Sparrowhawks observed at the roost. The Greenfinches departed earlier than expected at high, and later than expected at low light intensities.
