ABSTRACT Plant biogeography and ongoing changes in plant distributions are influenced by long‐distance dispersal (LDD) of seeds, migratory waterfowl (Anatidae: Ducks, geese swans) particularly important for the plants around wetlands through gut passage (endozoochory). However, this is not contemplated classical syndromes; hence, currently we have limited understanding what angiosperm traits predict seed any differences due to avian trait variation among species. We conducted a literature search data on presence seeds alimentary canal or faeces North American as proxy interactions, since an fraction these survives passage. present list flowering species ( N = 536) from 95 families potentially dispersed 38 species, together with their vectors. Owing largely sampling effort, 47% 35% genera recorded were only found single A suite analytical approaches revealed major whose ingested likely between foraging groups (guilds) relation other traits. Diving ducks sea associated sublittoral that submerged floating leaves, hence hydrochory syndrome. Dabbling herbivorous (notably geese) terrestrial herbaceous plants, also unspecialised syndrome common plants. Plants larger greater height more be dabbling ducks, whereas shorter than waterfowl. Network analyses interactions generally consistent results, but provided evidence all geese, duck alike along terrestrial–aquatic gradient, instead occupy distinct niches. The traditional classification into guilds therefore does accurately reflect differing roles ingestion seeds. Aquatic had vector ones.
