Abstract

Small flocks (20–40 individuals) of feral rock doves (Columba livia) studied in downtown Montréal follow a bimodal daily schedule of feeding site attendance. The bimodal schedule is achieved through a summation of different usage schedules in the various areas of the sites. The latter schedules are not necessarily bimodal and reveal clear differences between individuals that otherwise share some common feeding areas. The existence of these individual differences has implications for two of the mechanisms by which flock feeding may benefit birds, information centres, and the skill pool.
