Abstract: Isolated trees in pastures are now often, due to increasing devastation of forested areas, important feeding places for migratory or generalist birds. These trees serve both as food sources and as deposition sites for seeds from fruits consumed in neighboring areas. The objective of this study was to identify the avian consumers of the fruits of Cytharexyllum myrianthum trees in open pastures and describe their feeding behavior and how it influences seed dispersion. Forty two hours of observations included 198 feeding bouts of nine bird species. Turdus leucomelas (Muscicapidae) was the main consumer (28% of fruit consumption), swallowing the entire fruit. Next, was Tyrannus melancholicus (Tyrannidae, 23%), which may be the most efficient seed disperser of C. myrianthum because it regurgitates the seeds on sites far from the parent tree.
