Tropical rain forests have a vertical layering with multiple strata: the emergent layer, the canopy layer, the understory layer, and the forest floor. This allows for a greater number of bird species due to the availability of more habitats and resources. Savannas and deserts, for example, have fewer vertical strata and therefore fewer bird species. The temperate broadleaf forest and temperate grassland also have fewer strata compared to the tropical rain forest.
