Even if this Ficus community as a whole does not seem to interact with birds, it remains relevant, though, to test whether F. To support future forest recovery projects based on plant-animal interactions, this work aimed to evaluate the ornithochoric species and fruit consumption by birds in both a mosaic of seasonal semideciduous forest and a mixed reforested area in Rio Claro, Sao Paulo, Brazil.

Frugivorous interactions with large sized birds, such as the Cracidae and Ramphastidae families, considered as potential seed dispersers, were not recorded. Mean fruits survival time days between fragments and continuous forest for woody plant species or species with other life forms. The main birds observed consuming fruits are small size and omnivorous. Despite the prevalence of generalist birds that disperse mainly small seeds of plants from the early succession stages, we found the PFSP has a diversified frugivorous bird-plant interaction network compared to other forest fragments of the State, due to the variety of available environments, connection with other surroundings fragments and its medium size and rounded shape, softening the matrix impact.
