We also hypothesized that insectivores increase their foraging from associating with the babblers, and would thus be most attracted to babbler vocalizations.
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.
