【 摘 要 】

Fourteen bird species were observed visiting one specimen of Alchornea glandulosa Poepp., 1845, at the Horto Florestal Navarro de Andrade, Rio Claro, São Paulo State, Brazil. Among them, three species seem to be the most efficient seed dispersers of A. glandulosa at the study site: Myiodinastes maculatus (Müller, 1776), Empidonomus varius (Vieillot, 1818) e Tyrannus melancholicus Vieillot, 1819. Besides to swallow fruit whole, these birds contributed with 68.5% of the total feeding visits. A. glandulosa fruit are not the mainly part of the diet of any one of the observed bird species, since they do not fit in the frugivorous specialized category. However, as almost all the observed individuals swallow fruit whole, it is suppose that they promote an efficient dispersion of their seeds.
