What is an example of behavioral isolation

Behavioral isolation is demonstrated in species of finches. Their mating calls are distinct yet unique across species.

Explanation:

Mutations arising from errors within gene replication often accumulate within populations, becoming more stable. They may lead to the formation of separate, genetically distinct populations called species. These new species arise via:

Behavioral isolation is an isolating mechanism that is part of sympatric speciation. Here, there are apparent non-physical barriers to prevent mating, and several related species live within a population and gene-flow.  However, reproductive isolation occurs through assortative mating (mate choice based on shared traits) which may lead to heteropatric speciation.

Commonly observed in birds, it involves distinct and unique courtship and mating signals. Mates only respond to those fitting the required behavioral patterns such as a courtship dance, nest building, foraging and songs.
