Dominance hierarchies have long been observed in nature across many different species. These hierarchies often arise via agonistic behaviors, whereby animals compete for resources while minimizing their physical conflict. Understanding these interactions is important for determining factors that contribute to community structure. We examined interspecific dominance hierarchies of frugivorous neotropical birds at feeding stations baited with bananas in the Wilson Botanical Garden of the Las Cruces Biological Station in Costa Rica.
