The effect of the dominance hierarchy and the season was studied on different aspects of mixed-species bird aggregation at feeders, such as the group size, feeding propensity, and strategic interaction among birds. To achieve these goals two types of feeders namely: gauze ball feeders and bottle feeders were used. The study was conducted in winter accounting for the non-breeding season and spring for the breeding season in three sites around České Budějovice, Czech Republic.
