The aim of this study is to identify the species of birds that feed on the fruits of Miconia floribunda (Bonpl) DC. and describe their foraging behavior, which influence on seed dispersal processes of the species in an area of the National Park of Yariguíes Serranía (Santander, Colombia). The area is home to forests in good condition to serve as transition between the Magdalena River valley and the highlands of eastern Colombian Andes. Seed dispersal is a fundamental process that models the structure of the vegetation cover, promotes the establishment and perpetuation of the same, to abundant bird life and is a constant source of food. The observations showed a sampling intensity of 19 hours per researcher, accumulating a total of 57 hours of observation. 176 events were recorded frugivory, recording 13 species of birds belong-ing to four families, predominantly Thraupidae family with 10 species belonging to five genera, which constituted 89% of the frequency of visits for this study. There were two types of manipulation of the fruit: engulfed and mash. For two species of Diglossa manipulation technique was macerated fruit so it may be less efficient seed dispersal because they dropped some of the fruit in the vicinity of the parent plant, which de-creases the chances of recruitment.
