|A homogeneous environment is also important, as patchy resources in space and/or time can allow coexistence of competitors.|
Overlapping species with similar ecological requirements can also coexist by "niche-partitioning". Diet specialization is one way. We see this in some species of Darwin's Finches, who, when food is abundant, are seed generalists. During drought, however, as the food supply dwindles, the different species avoid competition by specializing-- those with larger beaks seek the harder seeds, leaving the softer ones to the smaller birds.
