| It has been postulated that the model and the mimic should always occur in the same area i.e., be sympatric. |
| Most studies of interspecific competition consider sympatric congeners because it is assumed that closely related species tend to compete more strongly. |
| These two sympatric species are reproductively isolated and represent highly divergent lineages in the genus. |
| For example, interspecific agonistic interactions select for dull-colored male flycatchers that experience less interference from more aggressive, sympatric congeners. |
| One of the chief roles of calls among songbirds is to find mates, and that takes me back to the topic of sympatric speciation. |
| Field work in Michoacn revealed that two supposed subspecies of Pituophis deppei were sympatric. |
