Flowering plant species and their nectar‐feeding vertebrates exemplify some of the most remarkable biotic interactions in the Neotropics. In the Brazilian Atlantic Forest, several species of birds (especially hummingbirds), bats and non‐flying mammals as well as one lizard feed on nectar, often acting as pollinators and contributing to seed output of flowering plants. We present a dataset containing information on flowering plants visited by nectar‐feeding vertebrates sampled at 166 localities in the Brazilian Atlantic Forest. This dataset provides information about 1902 unique interactions among 515 species of flowering plants and 129 species of potential vertebrate pollinators and the patterns of species diversity across latitudes. All plant‐vertebrate interactions compiled were recorded through direct observations of visits, and no inferences of pollinators based on floral syndromes were included. We also provide information on the most common plant traits used to understand the interactions between flowers and nectar‐feeding vertebrates: plant growth form, corolla length, rate of nectar production per hour in bagged flowers, nectar concentration, flower color and shape, time of anthesis, presence or absence of perceptible fragrance by human, and flowering phenology as well as status of plant’s threat status by IUCN classification. For the vertebrates, status of threat by IUCN classification, body mass, bill or rostrum size are provided. Information on the frequency of visits and pollen deposition on the vertebrate’s body are provided when available on the original source. The highest number of unique interactions is recorded for birds (1771) followed by bats (110). For plants, Bromeliaceae contains the highest number of unique interactions (606), followed by Fabaceae (242) and Gesneriaceae (104). It is evident the geographical bias of the studies throughout the southeast of the Brazilian Atlantic Forest and the highest efforts directed to flower‐hummingbird interactions. However, it reflects a worldwide tendency of more plants interacting with birds than other vertebrate species. The lack of similar protocols among studies to collect basic data limit comparisons among areas and generalizations. Nevertheless, this dataset represents a notable effort to organize and highlight the importance of vertebrate pollinators on this hotspot of biodiversity on Earth and represents the data currently available.
