Movie S1: Nectar lapping in Glossophaga soricina (Detail). In each lapping cycle hairlike papillae trap a nectar coating around the tongue that is transported into the mouth (nectar presented 20 mm below the feeder opening; time expansion 75 x)

Movie S2: Feeding Lonchophylla robusta (Overview), illustrating the constant contact between the tongue and nectar throughout the entire visit (nectar level 20 mm; time expansion 50 x).

Movie S3: Tongue of Lonchophylla robusta (Detail, lateral view). Nectar is transported through the canal through pumping movements of the canal structures (nectar level 20 mm; time expansion 75 x).

Movie S4: Tongue of Lonchophylla robusta, near maximum extension (Detail, lateral view). Feeding is even possible when only the tip of the tongue is in contact with the nectar, as illustrated by nectar appearing in the canal starting at 00:13 s (nectar level ca. 38 mm; time expansion 75 x).
