Online Resource 2: Proportion of two-species flocks, in different tropical forest sites, that contained at least one intraspecifically gregarious species

Table 1. Proportion of two-species bird flocks, in different tropical forest sites, that contained at least one intraspecifically gregarious species. Data was obtained from the Dryad data package (Sridhar et al. 2012a) linked to Sridhar et al. 2012b. Information on intraspecific sociality of species was obtained from different field guides and field observations

Location / Total flocks / Two-species flocks / Two species flocks containing atleast one intraspecifically gregarious species
Malaysia: Fraser's Hill / 76 / 9 / 8
India: Parambikulam / 205 / 7 / 6
India: Gujarat / 61 / 12 / 10
Taiwan: Fushan / 126 / 28 / 27
Thailand: Khao Yai / 75 / 9 / 8
