Mixed species foraging flocks of avian insectivores are a consistent and worldwide phenomenon in forest habitats. Future studies should be designed to determine if similar results are found in other neotropical island communities that have high insectivore densities. In the insectivore anamniote clades, strong selective pressures were concentrated on the visual system to detect object size and movement. In terms of gross biomass, omnivores (7%) rival aerial insectivores but the remaining guilds account for only 8% in total. The guild composed of highly cluttered/gleaning frugivores was the richest in species (18), followed by highly cluttered/gleaning insectivores (12 species). The proportion of the ten prey larvae consumed per plot and the number of predation events in each plot by each insectivore species were recorded. Fruit-eating species and fruit-eating insectivores accounted for 65% of captures. The distribution of species through diet classes was similar for forest and gap species (63% of insectivores + nectarivores in each). We conducted analysis separately for insectivores and for omnivores/frugivores. We have used this approach to characterize the cones of insectivores. Given the current taxonomic status of the insectivores, it is unlikely that their retinae represent a "primitive", prototypic arrangement. In our data set, for instance, nonhuman simians have on the average about five times the brain size of insectivores when body size is controlled. After exclusion, the following four guilds were retained: frugivores (four species), omnivores (three species), gleaning insectivores (three species) and aerial insectivores (five species). The guilds highly cluttered space/aerial insectivores, highly cluttered space/gleaning insectivores, and highly cluttered/gleaning nectarivores, had no canopy species.
