We sampled weighted plant-bird interaction networks at two sites in the Manú Biosphere Reserve in the Andes of south-east Peru: Wayqecha (13.2S, 71.6W, 3000 m, upper montane rainforest) and San Pedro (13.1S, 71.6W, 1500 m, lower montane rainforest). At each site, we installed plots of 100 m x 30 m (six plots in Wayqecha, eight plots in San Pedro) and sampled networks four times approximately every three months between December 2009 and September 2010. In each round, we observed each transect for 30 h on five consecutive days and recorded which bird species fed on which plant species (total observation time 720 h in Wayqecha and 960 h in San Pedro). The Wayqecha network consisted of 1344 interaction events (a bird visiting a plant and consuming fruits) between 26 bird and 51 plant species, and the San Pedro network consisted of 4988 interaction events between 61 bird and 53 plant species. For all birds, we collected the following morphological traits: beak length and width, Kipp's distance, and body mass. Bird traits were measured on museum specimens or compiled from literature. For all plants, we collected the following morphological traits: fruit size and diameter, crop mass, and plant height. Plant traits were sampled in the field.
