Many species mob predators to drive them away. Mobbing carries personal risk, but the risk of injury or death declines and likelihood repelling predator increases in larger groups. The capacity evaluate number mobbers before joining a mobbing group may be highly beneficial for individuals when deciding join. Although recent studies have found that birds can use individual vocal discrimination assess conspecifics involved initiating events, it is little known whether are able heterospecific mobbers. In this study, we investigated heterospecifics responding calls Great Tits Parus major was influenced by callers (a mix Tit simulated playbacks live attracted playbacks, range one seven callers). total positively callers, with more than smaller However, these results driven calls, call overlap increased noise generated additional mobbers, not per se. These findings therefore allow us inclined join consists cannot tell callers.
