| These highly specialized birds feed almost exclusively on fruits, supplying fruit even to their nestlings, and hence are called frugivores. |
| Ethanol vapor emanating from palatable fruit may act as an odor cue, guiding bats and other frugivores to the fruit, and aiding them to assess its quality. |
| In tropical rainforests, the majority of woody plant species disperse seeds via vertebrate frugivores. |
| During the late Cretaceous and early Paleocene periods plant-eating mammals were frugivores, presumably because fruit can be more easily processed than foliage. |
| Furthermore, fruits in the forest canopy support a disproportionately high amount of bird biomass, because in general frugivores tend to be very large. |
| Moreover, palm fruits have been proposed to be keystone resources for Neotropical vertebrate frugivores. |
