Resource partitioning

Resource partitioning = species divide shared resources by specializing in different ways
Ex: one species is active at night, another in the daytime
Ex: one species eats small seeds, another eats large seeds

Resource partitioning can lead to character displacement = competing species evolve physical characteristics that reflect their reliance on the portion of the resource they use
Ex: birds that eat larger seeds evolve larger bills
Ex: birds that eat smaller seeds evolve smaller bills

Competition is reduced when two species become more different
