  1. “Birds Obs/Count”: average number of birds observed per count and standard error displayed; “Species richness”: number of species observed across the two years; “Shannon’s index” diversity index. Proportions of each combined epidemiological functional group (EFG) are displayed in each ecosystem (Ans = anseriforms, Cha = charadriiforms, RoC = Rest of Community, Res = resident, Afr = afro-tropical, Pal = palaearctic). In bold, dominant EFGs for each ecosystem.
