What makes it possible for the coexistence of several warbler species which feed on the same insect larvae?
The birds eat in the same area of different fir and spruce trees. The warblers do not experience intraspecies competition. The birds eat in the different portions of the forest canopy. The birds eat in the same portion of different evergreens. Some of the warblers are diurnal and some nocturnal.
The coexistence of several warbler species that feed on the same insect larvae can be attributed to the fact that the birds eat in different portions of the forest canopy. This allows them to exploit different niches within the same habitat, reducing direct competition for food resources. By occupying different vertical layers of the forest, each species can find its own food without competing directly with others, which facilitates their coexistence.
