Frugivory and North American Migrants in a Neotropical Second-Growth Woodland

Bird species visitation to a single fruit source fluctuates over time due to changes in fruit density, presence of behaviorally dominant birds, and availability of alternative fruit sources. As a result, different bird species are major consumers of a fruit source at various periods of the fruiting season. Large dominant birds exploit a small-fruited species mostly at its peak availability. Large dominant birds displaced small birds, so small birds used the fruit less when dominants were abundant. Frugivorous migrants increase in abundance in late spring, due to migration, and they outnumber non-migrants in their representation at fruit sources.
