The genetic data can be interpreted in light of what is known about indigobird behavior is as follows: While song learning and mimicry results in the cohesion of indigobird species and/or populations utilizing a particular host species (Balakrishnan & Sorenson 2006), young indigobirds learn these songs of the host while in the care of their foster parents.
